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.

Network on Board

Nowadays, commuters demand for “Internet on board” has made the information and infotainment systems essential in trains. The M12 network connectors with a mechanically robust design, in compliance with IEC 61076-2-101, together with high quality cables meeting the requirement of EN 45545-2 will ensure reliable communications. The heavy-duty connector, compliant with IEC 61373, with modular contact inserts form a flexible and safe transmission of signal and power circuit on rolling stock carriage connection and simultaneously ensures comprehensive protection in the event of electromagnetic interference fields.

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.

Hybrid Motor Starters – CONTACTRON

From |

Phoenix Contact’s Contactron is a range of hybrid motor starters that is engineered and design to replace the traditional way of starting, stopping and managing the motor. And with that, it comes with numerous advantages and benefits to the system integrator, contractor and end user.

The most obvious advantage is the space savings it brings if one chooses to use Contactron instead of the using the usual contactors and thermal overload relay. The space savings can range from 50% to 89% depending on the motor configuration.

With space savings, one can design their panel or cabinet to be smaller. This is useful for sites where space is limited such as on top of a shipping port cranes. An even more remarkable savings can be achieved by using the Contactron to shrink the size of an Ex d explosion proof box by replacing the contactors and thermal overload relay.

Contactron comparison with traditional motor starter

Contactron setup compared to traditional motor starter setup

Secondly, the Contactron can very much reduce the downtime of a plant or factory as it can perform on average 10 times the typical service life of the traditional contactors. This is because, rather than depending on the ‘prone to failure’ nature of mechanical parts of the contactors, the Contactron uses a combination of solid state and electromechanical relay. Therefore, for motors that are subjected to frequent start stops, the Contactron is an obvious winner.

Besides that, the Contactron can be connected and communicated to a higher level control and monitoring system. This allows crucial information on statuses of the Contactron to be sent to the control system using common protocols such as Modbus, Profibus and Internet IP. This is crucial for visibility and productivity of the plant or factory operators. The traditional contactors with no intelligence have no possibility of being connected to a control system.

Besides, the above, there are many more advantages of using Phoenix Contact’s Contactron over traditional motor starters.

Pluggable Compact (PLC) Relay

Pluggable Compact PLC Relay

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.

    MINI Analog Pro isolating signals

  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.

    MINI Analog Pro converting signals

Network-capable hybrid motor starters

From |

The new versions of the Contactron hybrid motor starter from Phoenix Contact enable quick and easy integration into the common fieldbus systems Profibus, Profinet, CANopen®, DeviceNet, Modbus, and EtherNet/IP™.

4732

Process data, such as motor current, is transmitted to the control system via the bus system with the aid of the corresponding gateway. This allows service intervals to be optimized, which plays a role in increasing system availability.

Thanks to the efficient wiring concept of the hybrid motor starter, the new devices also enable easy integration of the fieldbus with a short startup time. Mounting is easy with the DIN rail connector as the devices make contact as they snap on. The control signals are forwarded via the fieldbus system, therefore there is no need for digital outputs for motor control on the controller side. The extensive parallel cabling of the control and signal level is no longer required. All in all, the system offers a compact and economically attractive solution for motor control.
