Relay outputsThe outputs are electrically decoupled and of redundant design.
Connection
- Two buttons each with one normally closed contact and one normally open contact that are monitored for simultaneity according to EN 574. In this way a high level of protection against tampering is provided.
- Short circuit monitoring to detect short circuits between the connection cables and to shut down the outputs or prevent relay starting if necessary
- Earth fault/ground fault monitoring to detect short circuits between the connection cables and earth or ground and to shut down the outputs or prevent relay starting if necessary.
Connection optionsBy using suitable wiring the following function can be selected:
- Monitoring of downstream relays or contactors
