Wiring Safety Output
Integration in a one-channel release circuit without contactor monitoring
Two safety relay outputs are connected in series. The release circuit can be connected to
further components which are then wired to a common EMERGENCY STOP device.
Integration in a two-channel release circuit without contactor monitoring
Both safety relay outputs are integrated separately into the release circuits. These can be
connected to further components which are wired to a common EMERGENCY
STOP
device.
Integration with contactor monitoring
The motor contactors for dangerous movement are connected to both safety relay outputs.
For this purpose, forced contactors have to be used. In the connection diagram, no fuses
are included. However, for correct function those are absolutely required. The maximum
contact load of the safety relay outputs is 4 A with 24V DC.
