Specification
Relay outputsThe outputs are electrically decoupled and of redundant design.
Connection optionsBy using suitable wiring the following functions can be selected:
Electrical connection ratings
Other
Reliability values according to EN ISO 13849-1
- 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 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.
