Is space and cost a concern for you when designing-in relays for automation?

Phoenix Contact’s PLC Relay eliminates the need for extra terminal blocks, helping you reduce both space and cost. Let us see how.

PLC Relay Actuator Series

PLC Relay-Actuator Setup

Relay-Actuator Setup

In applications where only one normally-open(N/O) contact function is required, you can use Phoenix Contact’s PLC to Actuator output relays to interface with actuators, such as motors, contactors or solenoid valves.

You can connect all actuator connections, including the load return line, directly to the relay. Hence, eliminating the need for additional output terminal blocks to transfer power.

The benefit is daisy-chaining or looping the wiring for the power will not be necessary. This is illustrated in the wiring layout below.

Signal Conditioning – Why we need to isolate, convert, filter and amplify control signal

From |

When dealing with Measurement and Control signals, Signal Conditioners are crucial for the healthy operation of the whole system. Let’s find out why:

  1. Electrical Isolation – The most important task of a signal conditioner is the electrical isolation of signals. A reliable Signal Conditioner offers consistent isolation of input, output, and supply. As such, ground current loops can be prevented in the event of potential differences, which would otherwise lead to a distortion of the measured process values.

  1. Convert – An advantage of signal conversion is the conversion of sensor signals into a signal that can be read by the controller, such as PT100 in 4…20 mA. In addition, failure-prone signals such as 0 – 10 V, for example, can be converted into non-prone current signals.

  1. Amplify – Signals always need to be amplified in the event that cables are long or if high loads are to be driven. It is here where the signal conditioners must provide a high output power at a low input power.

  2. Filter – In industrial environments, interference often occurs as a result of high-frequency signals. The input filters of the signal conditioners therefore reliably filter out such interference signals.

Ethernet HART Multiplexer – Transmit Process Data Via Ethernet

From |

Process plant with engineersDid you know that in the Process Industry, there are more than 40 million devices that are running on the HART Protocol and more than 75% of them are HART-enabled. However, up to 90% of these HART-enabled device are being under-utilized, used only to read the 4…20mA signal.

In the current trend of IIOT, there is a growing need for diagnostic data to be analyzed in order to reduce operating cost and increase system availability. The time from obtaining the diagnostic data to analyzing and determining the next course of action has to be almost instant.

In the past, if access to the HART data was needed, users typically installed an RS485 HART multiplexer connected to a PC. Whenever data from a particular field device is needed to be read, it can take a long time depending on the number of field devices connected to the RS485 HART multiplexer. This is because RS485 HART multiplexer works on a “master and slaves” principle.

Ethernet HART Multiplexer

Instead of using the RS485 HART multiplexer, Phoenix Contact introduced the Ethernet-based HART multiplexer. Our Ethernet HART multiplexer allows the user to easily parameterize and monitor field devices on the Ethernet network. The modular Ethernet HART multiplexer accesses other HART-enabled field devices using Ethernet-based fieldbuses such as PROFINET, Modbus/TCP, and HART IP.

Each device is an individual HART master which can be connected to higher-level, fast Ethernet network infrastructures. Up to 40 HART devices can be connected to existing configuration tools such as PACTware, Simatic PDM, Honeywell FDM, HART OPC server or HART server. End users therefore save time and costs since configuration and calibration, e.g. partial stroke test, process monitoring or current loop tests, are controlled via Ethernet and everything can be performed during active operation.

Pick and place machine

‘Pick and Place’ Machine with THR components.

Do not judge a connector’s cost-effectiveness just by its price. Its ability to improve the overall efficiency of the manufacturing process counts as well. This is where THR technology shines.

The most common method of manufacturing  a PCBA (Printed circuit board assembly) typically requires 2 process flows. Reflow soldering is used to mount the Integrated chip (IC) and passive components in the first process flow. This is then followed by a second flow utilizing wave soldering to mount the terminal blocks and connectors.

The process can be optimized but that usually comes at a cost, e.g. installing a new machine. Hence, that eventually translates into a higher manufacturing cost in the short term. Is there a way to achieve higher efficiency in PCBA manufacturing without the accompanying costs?

Higher efficiency at Lower Or No Cost?

Yes. It can be done.

This is achieved by introducing connectors that are suited for the existing process line yet reduce the process flows to just one.

This is made possible by the integration of Through Hole Reflow (THR) components in Surface-mount technology (SMT) installations, which dominate today’s assembly manufacturing process.

Through Hole Reflow (THR) – Assembly In Just One Process

The benefit of THR is to use the existing Surface-mount device (SMD) machines and remove the 2nd process, the wave soldering, thus reducing the manufacturing a complete PCBA into a single process.

While it is the ideal situation to switch to an all-THR component solution, some components will still require wave soldering. Even so, there can still be a significant cost savings to make the switch.

Through Hole reflow Connector (THR)

Through Hole Reflow Connector (THR)

While there will not be a need to make changes to the existing equipment, some modifications will be required. For example it may require a change in the PCB design, an adjustment in the reflow profile, etc.

These changes, however, will reduce the amount of man-hours required for wave soldering. Based on a typical PCBA consisting of 80% of ICs and 20% of terminal blocks & connectors, the switch could achieve up to 20% of cost savings as THR components fully supports ‘pick and place’ machines.

3 Good Reasons For An Intelligent PV Panel Shutdown

From |

solarcheck_rsdPhotovoltaic (PV) systems are becoming an important source of power in recent years. With the rise of installation of such PV systems, the risks of working with high voltages should not be ignored. In 95% of the installation, the PV panels are connected in series with strings and are capable of generating DC voltages of up to 1000 V. This can result in life-threatening DC voltages as it cannot be disconnected easily on the DC side. Continue reading

Fast, Safe and Error-free System Cabling for Control Systems

From |

How do we connect the Controller to the various Digital or Analogue signals? Answers: Either with cables or with a wireless transmission medium.

In a control plant, we can easily have a few hundreds to tens of thousands of cables for control signals depending on the size of the plant.

Bad planning / discipline of the cabling routing could look something just like a plate of messy ‘fried noodles’.

Same, same but different.

A proper planned cable routing would look nicely as follow:

But still, a considerable amount of effort is required during installation, maintenance and fault finding – should something go wrong with the application eg. Fault tracing, wrong labeling, wrong termination…

Realizing the connection between field level and control level by means of system cables from Phoenix Contact would mean fast, safe and error-free system cabling for your control systems and no more messy ‘fried noodles’ to manage:

Maximize Your Year End Performance Review

From |

Happy Staff at meetingAs the year of 2016 is ending very soon, it is also the time to review the year’s performance, there is a growing trend that many companies are abandoning the traditional performance reviews. However recent researchers found that formal performance reviews still hold an important aspect for both supervisor and subordinates to make sure that they are on the same page about each other expectation. Instead of ditching the performance appraisal process, more importantly, how do we make the process more purposeful? The guidelines as follows:

A self-evaluation

Employee must be honest with themselves about how they have performed in the role. Take for example, an employee must be able to take note of the accomplishments when they exceeded expectations or have gone below and beyond the job description, and also to look at areas where they need to improve in term of performance.

Review of job description

Job description can be changed over the time, especially if there are changes in the organization structure. It is a great time to discuss the addition of responsibilities that may help employees to grow and achieve more fulfillment in their work.

Focus on outcomes

Supervisors must be able to evaluate objectively by focusing on the subordinate’s performance result, in this case, KPI scores can be a good base to measure an employee’s achievement; it is more like a black and white result, whether he/she met the given objective or scores.

Do not get defensive

The reason of having a review in the first place is to give and receive the feedback that will help to improve job quality and productivity. Avoid going on the defensive mode or blaming others for the performance failures. In fact, do not discuss about other teammates at all and focus solely on individual performance.

Plan ahead

Performance review is a good opportunity to discuss the goals for next year and beyond. Before the review, employees should be encourage to write down their goals, or if he/she has any skills gaps where supervisor may be able to provide additional training, resources, or guidance to help him/her achieving the goals.

Keep in mind that your performance review, whether overwhelmingly positive or somewhat disappointing, is always a great opportunity to learn, grow, and move forward in your career.

Till next year, Happy New Year!
