Compatible sensor types

The safety relay is suitable for:

•

Safety sensors and safety switches with OSSD output, e.g.: Electro-sensitive pro‐
tective equipment (ESPE) with a single-channel or dual-channel monitored active
switching output with cross-circuit detection (OSSD)

3.2.4

Restart interlock

A restart interlock can be implemented with a reset pushbutton.

3.2.5

External device monitoring

Permanent external device monitoring can be implemented using external wiring.
