Ismertetés
Relay outputs
The outputs are electrically decoupled and of redundant design.
Connection options
By using suitable wiring, the following functions can be selected:
- Relay start with automatic start, a start button or a monitored start button
- Monitoring of downstream relays or contactors.
- Simultaneity monitoring to monitor safety components over time
- Relay start using a monitored start button
- Short circuit monitoring to detect short circuits between the connecting cables and to shut down the outputs or prevent relay starting if necessary
- Earth fault/ground fault monitoring to detect short circuits between the connecting cables and earth or ground and to shut down the outputs or prevent relay starting if necessary.
Time-delayed shutdown
The release time for the time-delay contacts can be set as required using a potentiometer on the safety relay.
