In rail transport, relays with positively driven contacts monitor numerous applications that are essential for smooth and safe operation. For example, safety relays are used in the following railway technology applications:
In addition, Hengstler safety relays ensure that trains are automatically stopped when passing a red main signal. If a train passes through a red signal, a magnetic coil on the signal automatically sends this information to a corresponding magnetic coil on the locomotive. This magnetic coil then immediately activates the brakes of the train and thus brings it to a stop.
Hengstler safety relays can also be found in fully automated, driverless trains, e.g. at airports. There, they control all safety-relevant functions and thus enable a comfortable, safe operation.
