notice

Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.

notice - Wiring example

Relay outputs:

1-channel control of the expander module is suitable for contact reinforcement or multiplication of the connected safety relay

module.

Terminals X1 and X2 of the expander module must be connected to the feedback circuit or reset circuit of the safety relay module.

The wiring diagram shows the control of the expander module by a SRB... safety relay module with the guard doors closed and in de-energised

condition.
