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.

Let there be light: Phoenix Contact Components for Reliable Power Grids

On 7 July 2017, Phoenix Contact Singapore Team organised a’ Dining in the Dark’ event as part of Corporate Social Responsibility.  In the short 2 hours without our sight, we experienced a range of emotions such as fear and helplessness. This event also allowed us to understand the challenges that persons with visual impairment faced daily. It is truly a meaningful event that we are thankful to be able to experience with the friends we made from work.

Phoenix Contact's 'Dining in the Dark' CSR Event

Phoenix Contact’s ‘Dining in the Dark’ CSR Event

In today’s world, it might not be an exaggeration to say that we will feel the fear and helplessness if we do not have access to electricity. For a start, life-sustaining equipment in hospitals will not be in operation. Many of life’s conveniences such as lights, entertainment, air-conditioning etc. will be stripped from us. For this, electrical grids are always considered critical infrastructure all around the world and efforts are made to ensure the grid is always operating. Phoenix Contact contributes to this reliability with our products. Below are some examples:

    1. Terminal blocks (Clipline Complete)Clipline terminal blocks
      Our terminal blocks are widely used in power industry. For quick installation in Marshalling/Pilot panel, our customers prefer the use of

      • Push-in connectionThis connection method is fast, do not require special tools, safe, ensure consistent and good connection for every insertion and ideal for areas with high vibration. Most importantly, unlike screw connection, over time, push-in connection does not loosen.
      • QTC connectionThere is no need to strip the wire using QTC connection, making it the fastest way for wire installations. Moreover, Phoenix Contact QTC terminal blocks do not require special tools!
    2. Protection terminal blocksURTK-6 Test Disconnect Terminal Block

      Especially for CT testing, where you have to make the testing circuit before breaking the transformer circuit, it is important to ensure that the “make-before-break” is done properly! Failure to do so results not just in power outage, but often death.

      Our solution is our range of test disconnect terminal blocks, clearly labelled to ensure operators know exactly what is being done. There are also ample spaces for accessories for you to do the necessary bridging and testing.

      Offering inspiring innovations, Phoenix Contact has come out with a test disconnect system. Instead of manually doing the switching, why not let our system take care of it for you with Fast And Modular Energy system (FAME).

The Flashtrab-SEC-T1+T2 protective device combination consists of line-follow-current-free type 1 lightning arresters on the basis of a spark gap and varistor-based type 2 surge protective devices. This combination, in just one device, is the only one on the market worldwide.

4762

Thanks to Safe Energy Control technology (SEC), the products are durable and powerful. The load of the entire installation is reduced to a minimum in the event of lightning. The lightning arrester combination provides specific protection for installation environments with frequent switching operations. High lightning currents are safely controlled from the spark gap free of line follow current and temporary surge voltages are reliably limited by the varistors. The resulting low voltage protection level and fuse-free use in 230/400 V power supply systems are further advantages of this product range.

The compact arrester reduces the effort required for installation and maintenance. All products are pluggable and can be tested with the test device for the Checkmaster 2 surge protective devices.

Durable and powerful type-1 lightning current arrester

The Flashtrab SEC-PLUS type-1 lightning current arresters from Phoenix Contact, which are particularly durable and powerful thanks to Safe Energy Control Technology, have just been complemented by two product variants:

The Flashtrab SEC-PLUS 440 product variant is particularly suited to special industrial applications with 440/690-V networks or 400-V power supply systems. The products impress with their strong shock and vibration resistance. This compact variant can be used up to 400 A without an additional backup fuse.

4752

The Flashtrab SEC-PLUS 350 variant is used in the pre-metering area of the main feed, or in industrial applications. High voltage fluctuations and lightning current loads are no problem for the type-1 arrester. The good protection level and backup fuse-free use up to 315 A deliver additional advantages.

Both variants are pluggable and can be tested with the CheckMaster 2 test instrument for surge protection devices. Like any other SEC family type-1 arrester, the Flashtrab SEC-PLUS devices are also type-2 arrester tested and certified.

The new VAL-MB product family from Phoenix Contact provides powerful and compact protective devices for photovoltaic applications with generator voltages of up to 1500 V DC. The protective devices are specially adapted to DC application requirements and certified by KEMA.

Longer inlet funnels and higher screw shafts provide additional protection against arcing. The product range includes protective devices for generator voltages of 600 V DC, 1000 V DC and 1500 V DC, as type-1/2 lightning current arresters, as well as pure type 2 surge protection devices. Variants are available with or without remote signaling contact. All protective devices have a short-circuit protection of 2000 A and can also be used in high-altitude plants up to 6000 meters in altitude.

Intelligent Surge Protection for Process Technology

Phoenix Contact’s Plugtrab PT-IQ surge protection devices for MCR and process technology warn plant operators before protection of the plant is lost. To achieve this, each voltage-limiting component in the protective plugs is continuously monitored. If the performance limit has been reached as a result of frequent surge voltages, this is indicated by a yellow signal on the protective device and via remote signaling. At this time, the arresters are still functional and the plant is protected. However, replacing the component is recommended to prevent unnecessary servicing.

4736

Plugtrab PT-IQ Ex protective devices are available for intrinsically safe areas. These devices can be installed in Ex Zone 2. The intrinsically safe protective circuits can be routed up to Ex Zone 0.

Thanks to multi-level monitoring and signaling, the plant operator always knows the status of protective devices and therefore has an overview of surge voltage protection in the plant. This intelligent surge voltage protection is available with traditional screw connection technology as well as innovative push-in connection technology. A controller supplies up to 28 protection modules with voltage and allows for connection of a central remote monitoring system.

The products are based on the Safe Energy Control Technology (SEC) from Phoenix Contact, which enables even high discharge currents to be kept safely under control. With the new push-pull mechanism, the protective device plugs are easy to remove and latch after being inserted in the base element in a vibration-resistant manner. The integrated backup fuse allows the lightning arrester to be installed easily and flexibly.

In comparison to installations with separate backup fuses, the new devices save up to 60% space, reduce wiring costs and effort, and allow customers to freely choose the installation location. The type 1 lightning arrester is suitable for use in 230/400 V power supply systems without a back-up fuse.
