IO Link

From |

Have you ever encountered the following situations?

  • Machine stops suddenly due to contaminated sensor/actuator
  • Stopping the machine in order to change to another color detection (or other parameters) on the sensor
  • Stopping the machine when replacing a faulty sensor in order to set the parameter of the new sensor

What if you can…

  • Re-parameterize the sensor without shutting the machine down
  • Replace a new sensor with the previous parameters automatically downloaded without shutting the machine down

The above is made possible due to the IO Link technology. IO Link is a standardized IO-technology (based on IEC 61131-9) focusing the communication between field devices and sensors & actuators. This enables the exchange of both process data and service data between the connection and sensor/actuator. With the IO Link technology, devices can now identify and configure themselves automatically. This will enable an easy replacement of defective components and reduces downtime significantly.

An IO-Link system consists of the following basic components:

  • IO-Link master
  • IO-Link devices
  • Standard 3-wire sensor cable/actuator cable

Phoenix Contact offers a comprehensive IP20 and IP67 portfolio of IO-Link masters, IO-Link devices, cabling, and software.

If you need further consultation on your next IO-Link application, please do not hesitate to drop us a message.

10 Things You Need to Know about Fibre Optic LC Connectors

From |

Fibre optic cables carry information using light and it is only slightly thicker than human hair. It transmits data faster and further than a copper cable, but you probably already know this. Instead of going into details about fibre optic cables, we are going to show you 10 things you probably do not know about the fibre optic LC connector.

  1. LC stands for Lucent Connector, sometimes also known as “little connector”
  2. It is one of the smallest fibre optic connectors in the market. It is half the size of a Square Connector (SC) which is the most commonly used fibre optic connector in the market.
  1. Although both LC and SC are classified as push-pull connectors, LC uses latch locking while SC uses locking tabs.
  2. The introduction of LC wasn’t a bed of roses. Due to the high licensing fee, it was not well-received when it was first launched.

  1. However, due to the factor of its small form, LC had slowly gained its popularity in applications that requires high density connections.
  2. LC is usually used in high density patch panel. High density patch panel provides the flexibility for future expansion.
  3. LC is the preferred connector for single mode fibre optic cables. Single mode is able to transmit a higher bandwidth over a longer distance. However, it’s more expensive as compared to multimode fibre optic cables.
  4. Phoenix Contact new modular patch panels enable users to connect up to 72 LC duplex connectors to optimise the use of space within control cabinets.
  5. Phoenix Contact compact splice box FDX 20 allows users to connect up to 12 LC duplex connectors. It is also one of the smallest splice boxes in the market.

  1. Besides LC connectors, Phoenix Contact offers a full array of fibre optic products and accessories including patch cords, reusable connectors and tools.

Stripping Wires Fast and Easy

From |

Stripping cables is one of the processes in wire harnessing, besides cutting and crimping processes.

There are many ways to strip a cable, from using the conventional cutter to using the manual/automatic wire stripping.

There are some basic points we need to know in doing the stripping process.

  1. Cable size
  2. Stripping length

Choosing the correct tool and setting the correct stripping length will produce the perfect stripping result for crimping process.

Manual Stripping Tool

With manual stripping tool, there are some concerns such as fatigue, consistency of stripping length and time.

Automatic Stripping Tool

All the concerns with manual stripping tool can be solved with the Automatic Stripping Tool.

Phoenix Contact knows this and has developed automatic Stripping Tool called WF 1000.

With this automatic device, we can strip cables without any fatigue, get the precise length and it takes only 0.3s per process.

This machine will boost your productivity with high quality output.

Features:

  1. This compact stripping machine automatically insulates conductors with a cross section of 0.08 to 6 mm2.
  2. Multi-strand cables with a diameter of up to 6 mm are also stripped.
  3. Partial stripping is supported.
  4. Special insulations such as PTFE and silicone can be stripped, in addition to standard insulations
  5. The clamping force automatically adjusts itself to the required extraction force. This reduces/prevents pressure points on sensitive insulation.
  6. The stripping dimensions are set individually via rotary buttons. They are shown on the clear display.

You can check out the video of the WF 1000 below!

Grounding System Types According to IEEE Standard

From |

Grounding (Earthing) is a system of electrical circuits that are connected to the ground that functions when a leakage current can discharge electricity to the earth.

According to Institute of Electrical and Electronics Engineers (IEEE) Standard 142 ™ 2007, the purpose of the grounding system is to:

  1. Limit the amount of voltage to the earth to be within the allowed limits
  2. Provide a path for current flow that can provide detection of the occurrence of an undesired relationship between the system conductor and the earth. This detection will result in the operation of automatic equipment that decides the supply of voltage from the conductor.

Characteristics of an Effective Grounding System

Based on the IEEE standards, the grounding system is divided into:

  1. TN-S (Terre Neutral – Separate)
  2. TN-C-S (Terre Neutral – Combined – Separate)
  3. TT (Double Terre)
  4. TN-C (Neutral Terre – Combined)
  5. IT (Isolated Terre)

Terre originates from the French language and means earth.

The first letter is the connection between ground and the power supply, while the second letter shows the connection between ground and electronic equipment supplied with electricity. The meaning of each letter is as follows:

  • T (Terra) = Direct connection to ground.
  • I (Isolation) = There is no connection to ground (even if there is a high impedance)
  • N (Neutral) = Connection directly to neutral power supply cable (where this cable is also grounded in the power supply)
  1. TN-S (Terre Neutral – Separate)

In a TN-S system, the neutral part of the electrical energy source is connected to the earth at one point, so that the neutral part of a consumer installation is directly connected to the neutral source of electricity. This type is suitable for installations that are close to electrical energy sources, such as for large consumers who have one or more HV / LV transformers for their own needs and if the installation / equipment is adjacent to the energy source (transformers).

  1. TN-C-S (Terre Neutral – Combined – Separate)

A TN-C-S system, has a neutral channel from the main distribution equipment (power source) connected to the earth and earthing at a certain distance along neutral channels leading to consumers, usually referred to as Protective Multiple Earthing (PME). With this system, a neutral conductor can function to restore the earth fault current that might arise on the consumer’s side (instation) back to the power source. In this system, the installation of equipment in the consumer only connects the ground to the terminal (channel) provided by the power source.

  1. TT (Double Terre)

In the TT system, the neutral part of the electricity source is not directly connected with neutral earthing on the consumer side (equipment installation). In TT systems, consumers must provide their own connection to the earth, namely by installing an earth electrode that is suitable for the installation.

  1. TN-C (Neutral Terre – Combined)

In the TN-C system, the neutral channel of the main distribution equipment (power source) is connected directly to the consumer’s neutral channel and the frame of the installed equipment.

With this system, a neutral conductor is used as a protective conductor and a combination of neutral and earthing side frames of the equipment is known as a conductor of PEN (Protective Earthing and Neutral).

This system is not permitted for conductors less than 10 mm2 or for portable equipment. This is because if a fault occurs, then at the same time the PEN conductor carries the phase unbalance current and the third level harmonic current and its multiples.

To reduce the impact on equipment and living things around the equipment, then in the application of the TN-C system, the PEN conductor must be connected to a number of electrode rods for earthing on the installation.

  1. IT (Isolated Terre)

From the first letter (I) it is clear that, in this type of IT system, neutral is isolated (not connected) to the earth. The PE point is not connected to the neutral channel but directly connected to the earthing.

In its application, the neutral point of the IT system is not really isolated from the earth, but is still linked to the Zs impdedance which has a very high value of around 1000 ohms to 3000 ohms. This serves the purpose of limiting the level of voltage overload when there is interference in the system.

TT IT TN-S TN-C TN-C-S
Earth fault loop impedance High Highest Low Low Low
RCD preferred Yes N/A Optional No Optional
Need earth electrode at site Yes Yes No No Optional
PE conductor cost Low Low Highest Least High
Risk of broken neutral No No High Highest High
Safety Safe Less Safe Safest Least Safe Safe
Electromagnetic interference Least Least Low High Low
Safety risks High loop impedance (step voltage) Double fault, overvoltage Broken neutral Broken neutral Broken neutral
Advantages Safe and reliable Continuity of operation, cost Safest Cost Safety and cost

Mini Analog Pro Signal Duplicator

From |

Do you have applications where you need to feed 4-20mA current from a transmitter to both DCS input and a digital display indicator? If yes, then most likely you will need a signal duplicator (current splitter). The module splits the current from 1 input 4-20mA to 2 output current.

While it is true that current is flowing with the same value if we put load in series, but one must observe the total load resistance in 1 loop. This includes if we draw long cables from transmitter to DCS and digital display. There is a maximum resistance value that a transmitter can be connected with. This is why we still need a signal duplicator module.

Phoenix Contact Mini Analog Pro Signal Duplicator has an output load resistance of maximum 500 Ohms per channel which is sufficient for most applications. Moreover, it has a Repeater Power Supply function, which means this module can be used for a 2 wire or 4 wire transmitter. It is also HART transparent if you are using SMART Device.

Another interesting feature is the module has NFC ready, this means huge benefits for users to set the module behavior. In the past, we need to rely on datasheets and then do manual setting via dip switch. This is no longer needed, just pick up your Phone and put it near to the module, then all the setting can be done via Apps.

Energy Day

From |

Over the past decade, we have done quite a number of seminars, but the Philippines’ Energy Day seminar concluded last Nov 22, was truly a successful one. Highlighting on the success was the jam-packed seminar room hitting more than 100% of the expected attendees, smooth registration, and attentive, lively and participating audience. I can’t say anything more but an unfading thanks to the speakers Gary and James, PxC PH team, Marcom team, IMAXX team, and of course to all the companies, guests and attendees who have lent their ears on these upcoming trend topics in the Philippines, which are Surge Protection and IEC 61850.

Clearly shows a very satisfied crowd and thumbs up on our two great speakers. This had made up my mind to repeat this success and to conduct Energy Day Part 2.
