Process Infrastructure – Ethernet HART Multiplexer

From |

Process infrastructure is one of the most critical parts of a refinery plant or offshore platform. The topology of modern process infrastructure includes FOUNDATION Fieldbus, Profibus PA, WirelessHart and HART Multiplexer etc.

HART (Highway Addressable Remote Transducer) is the most broadly supported protocol in the world for process industry as there are 40 Million HART devices being installed worldwide. But according to records, only 10% of these HART devices are connect to HART compatible control systems. End user should expand the use of HART devices in order to perform specialized operations like:

  • Asset Management
  • Predictive Maintenance
  • Data Logging
  • Partial-stroke Testing

Benefits of HART

Problems of Conventional Serial HART Multiplexers:

  • Slow scanning time due to large quantities of I/Os in the network
  • Limitation of RS485’s transmission speed
  • Work based on “Master and Slave” principle

Above are some of the challenges faced when using a conventional RS485 Hart Multiplexer and they will become worse if there are more than 1000 devices. Ethernet Multiplexer can solve this problem as featured below.

CCTV and Access Control in Indonesia

From |

Security Systems for the alternative energy source

Global oil prices have fallen sharply. From 2010 to mid-2014, world oil prices had been fairly stable at around $110 a barrel, but have now risen to around $50 per barrel. This influences future projects in the world. In Indonesia, the government postponed exploration projects (upstream). The government instead concentrated on developing projects downstream, such as TBBM (Terminal Bahan Bakar Minyak). At the same time, the Government develops project Refinery Unit, but focused on developing Security Systems.

The scope of work for a Security System is: CCTV, Access Control, Barrier Gate, Public Address/General Alarm (PA/GA) System and Radio. CCTV and Access Controls are more widely used in Indonesia today. For this project, we capitalise on the opportunities to provide components for CCTV and Access Control. CCTV and Access Control need a control panel. This control panel consists of Junction Box, Power Supply, Terminal Block, Cable, FO Converter and Surge Protection Device. Many brands exist in Indonesia, like Honeywell, Axis, Samsung and Pelco, to name a few. But for this project, the end user (pertamina) specifically needs a System Integrator, which is responsible for the design, installation, FAT, SAT and Commissioning.

We conducted a presentation for System Integrators in Indonesia where we explained the Junction Box, Terminal Block, FO Converter and Surge Protection Device. At January 2017 we received PO from System Integrator for Junction Box, Terminal Block and Surge Protection Device for project Refinery Unit at Pertamina Cilacap. The Integrator needed GRP Junction Box EXE standard. Phoenix Contact has SS and GRP. System Integrator needs SPD for power, Cat 5 and Cat 6. We can provide complete SPD. After that, we got PO for Surge Protection Device for project Refinery Unit at Pertamina Balogan. So for the next project we will try to offer a solution package. We will be offering complete Control Panel for System Integrator. The solution yields a lot of benefits for the customer as the system Integrator has time to focus on the other responsibilities. If the Control Panel has problems in the future, the engineering personnel would not be confuses as there is only one brand at the control panel. Imagine if one panel consists of different brands and the integrator has a lot of projects. The engineer has to check the old documents. Competitors don’t actively search for project related to Security Systems, they usually wait to get the PO from the System Integrator.

System Cabling Solution for Process Industry

From |

One of the challenges which panel builders in the process industry face would be space saving on control cabinets. Many Process retrofitting jobs require panel builders to ensure the quantity of cabinets remain even though additional I/O’s are added. System cabling is one of the best solutions to save space in control cabinets.  One of our panel builders solved their problems by replacing terminal blocks with our VARIOFACE Interface Module for the project.

Problems:

  • Additional 150 I/O’s on current system
  • Additional Controller Module
  • Cabinet Quantities need to be remained

After going through the product technical information, panel builder engineers decided to replace most of the signals with our VIP Interface Module due to space constraints. There are a total of 115 units of VIP-3/SC/D37SUB/F installed in this project. Photos of the panel are shown below.

Control Cabinet

Fig 1: Control Cabinet

VIP Interface Board

Fig 2: VIP Interface Board

Features of Interface Module:

  • Compact design of control cabinet space
  • I/O marking for field wiring clearly identified
  • Flexible marking of modules
  • Metal mounting foot allows for easy installation and removal on din-rail
  • Allows flexible module mounting positions

In addition to the space saving advantage, the site engineer shared that it is also time saving and fault free during the wiring termination. When the panels are delivered, the end user saves valuable time when installing and troubleshooting

CT Testing with FAME

From |

Test disconnect terminal block might not be an alien term to you, especially if you are in the power industry and dealing with switchgears. This is the most common component you will see in a control relay panel, which allows you to do testing and short circuiting of current transformers. At Phoenix Contact, we incorporate different connection technology into our test disconnect terminal block series, namely the screw connection, spring cage connection and push-in connection. Of course, the changes to our test disconnect product series do not end there.

Figure 1: (From left to right) Screw connection, spring-cage connection and push-in connection

While test disconnect terminal blocks offer flexibility to the user, as well as the benefit of saving space because of its modular design, it still has a slight disadvantage when it comes to testing. During function testing of current transformers and voltage transducers, performing combine switching operations across several points is often a requirement, and thus there will be limitations when it comes to such situations when modular terminal blocks are used. With all the constraints and limitations that comes with using a modular test disconnect terminal block, it opens up greater possibilities for the product development team to explore creative designs to solve the problem while maintaining the benefits of the modular terminal block. With that, ladies and gentlemen, I introduce to you FAMEFast And Modular Energy System, a solution specifically designed to cater to the need for performing complex switching operations, all at once.

Figure 2: FAME Plug and terminal strip

Figure 2: FAME Plug and terminal strip

If you find any of the above foreign to you, no worries! I have got you covered with quality posts by our product specialist. In this post, you will learn the fundamentals behind the make-before-break principle of a CT testing, as well as the reason for using test disconnect terminal blocks in such applications. Next, we look at FAME in detail from its basic operation to the difference between FAME 1, 2 and 3. These few posts will lay down the foundation for your understanding of the field of test disconnect systems.

While FAME is created for CT testing, and several versions of FAME have been developed for the different requirements of relay testing in different countries, we came to realize that there is room for other applications that FAME is able to offer. One specific example that best illustrates this is our recent product approval in Tenaga Nasional Berhad (TNB), Malaysia’s national grid operator. It all started with a product presentation of FAME 1 to the product approval committee members of the Protection Department of Transmission Division, with the purpose of having Phoenix Contact to be specified in as the test plug. However, things started to side track from our original plan when FAME 1 was proposed to be adopted as a secondary safety check in their Control Relay Panel. This is part of the initiative of TNB in the implementation of live maintenance. In this new add-on design, our FAME 1 will be sitting in between the first isolation (terminal block) and the trip coil.

Figure 3: Diagram of group isolation link in protection panel

This secondary isolation, also known as the group isolation link is used to isolate trip contact in a group.

  • It consists of two components, the power plug and the terminal strip.
  • During normal operation, the power plug is inserted into the terminal strip, forming a closed contact between the terminal block and the trip coil
  • When live maintenance is carried out, the power plug will be disconnected from the terminal strip, leaving an open contact.

Figure 4: (From left to right) Power Plug and Terminal Strip

This application in Malaysia is a good example and reference of how FAME can be adapted to serve different applications from its original design purpose. If you have a bright idea of how you can use FAME while reading this post, we welcome you to contact us. Who knows, your idea could be the next new application of our FAME!

FL 2000 Managed Switch for Railway Applications

From |

Highspeed commuter trainFor many years, Phoenix Contact has been a reliable partner of the Railway Industry, supplying products such as Power Supply Unit, Terminal Blocks, Heavy Duty Connectors for railway applications. In the recent years, Phoenix Contact has invested a significant amount of effort to create innovative products such as controllers and ethernet switches for automation applications.

Ethernet-based communication medium/protocols are becoming the norm in modern automation environments. Traditional serial-based communication medium/protocols are unable to support the requirements for transmission speed and data size; especially for time-critical applications.

FL 2000 Managed Switch

Phoenix Contact's FL 2000 Managed SwitchThe new FL 2000 Managed Switch was officially launched in April 2017 during the Hannover Fair. This new series of Ethernet Switch was specifically developed to bridge the gap between simple unmanaged switches and complex managed switches which are already available within Phoenix Contact product portfolio.

In railway applications, data integrity is especially critical to ensure the smooth and safe operations of the system. Transmission distances from various subway station control systems to the main control center are often in the range of kilometers, which conventional copper-based medium cannot handle. The only way to transmit the data over long distance is via Fiber Optic technology.

Our sales team spotted an opportunity to propose our FL 2000 Switch in one of the railway system upgrading project in this region. We managed to overcome several challenges despite facing strong competitions from various industrial giants. The main unique selling points of our FL 2000 Switch that met with approval of the end user and system integrators were:

  • Feature important automation features with attractive price/performance ratio
  • Easy/Flexible Configuration/Setup
  • Comprehensive approvals to meet stringent industry-specific approval requirements
  • Various connection port options: Copper and Fiber Optics; Gigabit network possible

In addition, we are also able provide a bundle offer including our UPS and Power Supply Unit.

If you would like to find out more about our FL2000 switches, check out our website or you can leave us your contact and we will get in touch with you as soon as we can.

Phoenix Contact – Your Partner in Safety and Reliability for Railway Industry

From |

RailwayPhoenix Contact has been serving the railway industry for decades, especially for rolling stock and signalling. Safety and reliability has always been our number one concern when developing products for railway applications.

Safety on Board

The basic requirement for safety and reliability is standard compliance. Phoenix Contact has been certified by the International Railway Industry Standard (IRIS) since April 2008 and this standard is based on the quality management standard DIN EN ISO 9001, which has been extended with international railway-specific requirements. The ongoing tests during the development and production cycle of the products are essential to guarantee the product quality.

On top of that, all rail-specific products from Phoenix Contact fulfill the standards of DIN EN 50155, an international standard covering rolling stock; DIN EN 50121 electromagnetic compatibility; and EN 45545, fire protection on rail vehicle. Besides, shock and vibration test, material test and other fire protection is also critical for the railway application.

Safety should not be limited to the big ticket items and should even be extended to the passive component level. For example, the cable markings like shrink sleeve should be halogen-free and fulfill DIN 5510-2 with an oxygen index of 34.9%. besides being halogen-free, the cable ducts should enable individual bars to be broken without using any tools or resulting in any burr through defined breaking points according to EN 45545-2 (R22/R23:HL3). Behaviour in fire is another key concern and the plastic used for Phoenix Contact’s terminal blocks is halogen-free polyamide PA 6.6; which meets the highest safety requirement of UL 94 V0.

Surge Protection

Surge voltages and lightning strikes are common issues in signalling, hence the surge protective device (SPD) become significantly important to maintain reliable signal transmission. Phoenix Contact’s SPD has been tested according to IEC 61643-21 and the plug can be disconnected for test and maintenance by using the portable test laboratory. According to IEC 62305-3, the SPD must be tested regularly and the test values should be documented and traceable. Additional features like multi-stage monitoring (green – operating, red – fail and yellow – reach performance limit) for predictive maintenance and remote signalling for early detection of overloaded SPD can help to further enhance reliability.

Power Supply

The power supply unit (PSU) is used to convert main AC to low-voltage regulated DC power and it should at least be compliant with EMC Directive 2014/30/EU, IEC 60950-1, DIN EN 61558-2-16 and UL 508. To ensure smooth operation and maximum uptime, the redundancy setup of the power supply cannot be overlooked.

A redundant system can made up of two power supplies and a diode or Phoenix Contact’s O-RING to prevent back flow of current. An ORING being a more advanced and modern redundancy module compared to the diode, comes with auto-current balancing (ACB) technology which ensures the power supplies work equally hard. This enables the power supplies to have a longer and more consistent lifespan.

The redundancy status as well as the status of the ORING can be monitored, whereas this cannot be done with a DIODE. The PSU becomes more reliable and dependable when it is capable of sending analogue signals to control system on measurement values such as real time current, voltage and power for early detection of operational fault as well as critical information to the user.

Importance of choosing the right PCB enclosure

From |

What is considered important when it comes to choosing the right PCB enclosure. Let us guide you through the process.

Price? Style? Service & support? Reputation of the supplier?

In the matter of fact, all of above are essential. The engineers should select the enclosure at first and then choice the mechanical & electronic components to suit the enclosure.
We need to consider

Material
The 3 common plastic enclosures are ABS, Polycarbonate, Polyester which are high functionality, light weight, flexible in design.

The Ingress Protection
The ingress protection classification DIN EN 60529 determines and rates protection against solid particle (e.g. dust) as well as liquid incursion.

The letters IP (ingress protection) is followed by a two-digit number; the first digit indicates the level of Solid particle protection and the second digit indicate Liquid ingress protection. IP Code

Environmental Considerations
How the enclosure will last over many years of operation depends on how well you evaluate the environmental impact of elements such as UV rays, temperature, airborne debris, etc.
Different materials offer varying degrees of impact resistance.

Dimensions
The internal and external dimensions of a PCB enclosure is extremely important. Sadly, in many cases, the PCB is chosen first and this makes it difficult for the engineer to source the best fit enclosure solution.

Modification of Standard Enclosures
The enclosure supplier may need to support modifications with value-added services that include drilling, milling, printing, color, etc. Some suppliers can even provide advance services like fitting membrane keypads, displays on the enclosure, etc as a complete solution.

Ease of Assembly
A complex PCB design may make it difficult to assemble electronic and mechanical components in the enclosure, which make is an important point to consider when selecting an enclosure.

Range of PCB Enclosure

Check out Phoenix Contact’s range of enclosures here

We, at Phoenix Contact, understand your problems and offer a wide range of options for shape, color, and function when it comes to choosing the right enclosure. Whether on a wall or on a DIN rail, from light gray to sky blue, narrow or wide, many many to choose from. With the two new enclosures, Universal case system (UCS)  and Environment case system (ECS) added into the selection, it is much easier to choose your enclosure.

Solar Power Energy – Standalone System (PLTS)

From |

A solar power plant, also known as Pembangkit Listrik Tenaga Surya (PLTS) in Indonesian, is a power generation system that uses solar cells (photovoltaic, PV) to convert sunlight into electrical energy.

Indonesia has vast landmass, a lot of which are remote areas. Thus, it is not possible for all to be connected to the grid (PLN = Perusahaan Listrik Negara = State Electricity Enterprise). However, with abundant sunshine all year round, Indonesia has the ideal setting with a high potential for solar power.

Currently, there are hundreds of small islands in Indonesia that have been installed with a Centralized PLTS. For islands or remote areas that receive general government assistance, the standalone PLTS have an output capacity of 5, 10, 15 and 30 kWp.

Solar Power Energy – Standalone PLTS

Example of a 2KW standalone solar power system

Image by Free Sun Power (http://freesunpower.com)

Called a standalone System or Off-Grid System because the system relies solely on solar energy as the main energy source. It utilizes a solar module circuit to generate electrical energy in accordance with the needs that have been planned.

Solar energy can be converted into electrical energy through the use of solar cells (photovoltaic). Solar cells are components that can convert solar light energy into electrical energy using the principle of the Photovoltaic effect.

The working principle of the photovoltaic effect is the emergence of an electric voltage due to the connection or contact of two electrodes connected to a solid or liquid system when obtaining light energy.

Image by University of Calgary – Energy Education (http://energyeducation.ca/wiki/images/1/11/Photovoltaiceffect.png)

Benefits of using Solar Energy :

  1. Solar energy is abundant and free
  2. Environmentally friendly
  3. Long life time period of use around 25 – 30 years
  4. Cheap maintenance costs
  5. Not Noise (Silent)

Disadvantage of using Solar Energy :

  1. Dependency on the weather
  2. Requires large area for installation of solar modules
  3. Big investment for initial installation solar energy

Efficiency of the PLTS (commonly around 80% – 93%) is determined by the degree of irradiation of the sun (the greater the irradiation value, the greater the power it can generate), the environmental (mountain or sea) temperature, dust and type of solar module, controller, inverter, losses of long cables.

So what makes up a PLTS Standalone System/Off-grid system:

  1. Solar Module
    Solar ModuleThe main function of a solar module is to convert solar energy into electrical energy. A Solar module consists of a number of silicon cells which when illuminated by the sun, will produce photons that can generate electrical current. A set of Solar Panels in one system is called an Array. Generally the most widely used solar modules are crystalline type either Monocrystalline or Polycrystalline. While thin film solar modules are still rarely used (in Indonesia). A solar cell can produce a voltage of approximately 0.5 volts. So a 12 volt solar cell consist of about 36 cells.PLTS Off-grid will consist of several solar modules according to their capacity. For example, a 10 kWp PLTS will consist of 50 units of 200 Wp solar modules or 100 units of 100 Wp solar modules. These solar module is arranged in series and parallel with certain configuration.
  1. Combiner Box
    Combiner BoxIn a solar power plant, solar panels can be arrayed in parallel to produce a larger current. Combiner boxes are  used to connect the positive foot of solar panels to one another. Similarly, for negative legs. The positive foot end of the solar panel is connected to the positive charge controller leg and so is the negative leg. The resulting solar panel voltage will be used by the charge controller to charge the battery.
  2. Fuse
    The fuse is a component to protect PLTS / PV network system. In the event of a short circuit or over-current on the circuit or other load, it cuts the flow of electricity.
  3. Charge Controller
    A tool to regulate the current and voltage both to the incoming current and voltage of the PV panel as well as outflow / used load currents. The voltage and current entering the battery should be as intended. When either is larger or smaller than the specified range, then the battery or other equipment will be damaged. In addition, the charge controller also serves as a guard to ensure the resulting output power remains optimal, in order to achieve Maximum Power Point Tracking (MPPT).
  4. Inverter
    Inverter is a converter that will change the DC voltage (48VDC, 24VDC or 12VDC) on the battery into AC voltage (220VAC or 120VAC) at the output will be channeled to the load. Off-grid inverter can adjust the amount of output power based on the amount of load. so it can be used to turn on household electricity such as lamps, fans, television, etc.
  5. Battery
    In a standalone system , the battery serves to store the solar energy generated during the day so that the energy can be used both in the day and night.The voltage on the battery bank PLTS is generally 48VDC, 24VDC or 12VDC. The battery type that is widely used for such applications is usually a Lead-Acid type, either OPzS (wet battery) or OPzV (dry battery). Batteries used in the PLTS system are a deep cycle type  which means the battery can be discharged up to 80% capacity (80% DOD).In addition to Lead Acid, the other battery type that can be used on a PLTS system is the  Lithium battery. As with any battery on our mobile phone, lithium batteries are known as batteries with high energy density which means the same volume of energy that can be stored by lithium batteries larger than other batteries.
  6. AC Breaker
    The AC Breaker is required to limit the power of the inverter so that the power being injected does not exceed the existing load, resulting in a fire.
  7. KWH Meter
    To measure the amount of electrical energy that has been produced by solar panel can be used kwh meter.
