Railway applications

The DIN EN 50155 standard applies for use in railway applications. In accordance with this standard, special requirements are in place for relays, particularly for:

• Operating voltage
  The operating voltage must be between 70% and 125% of the nominal voltage in order to be deemed suitable for railway applications. As standard, the range is 80% to 110% of the nominal voltage.
• Ambient temperature
  Relays in railway environments are often subjected to extreme temperatures from -40°C to +70°C. The reason is that some control cabinets are mounted in non-thermally-insulated steel housings beneath the passenger car.

PLC…RW coupling relays fulfil these particular requirements. Their spring connection also offers a high degree of resistance to shock and vibration.
 
Your advantages

• High degree of resistance to shock and vibration according to DIN EN 50155, thanks to spring-cage or push-in connection technology
• Optimum relay operation, thanks to wide-range electronics
• Time-saving potential distribution, thanks to jumpers
