Railways applications. Direct current signalling relays Ingestion-build-251241 Requires demonstration of continual energy1 Scope This European Standard gives requirements for direct current relays intended for safety related applications in railway signalling installations. This European Standard is applicable to monostable relays. However it can also be used as a guide for other relays such as with bistable relays.
