2d

Safety relay

The "Safe Torque Off" (STO) safety function can be requested by various devices. Switch
S1 can be, for example, an emergency-stop switch, a switch of a protective gate, a light
grid or a safety relay. The safety request is realised via two channels and via the switch
S1. As a result, the output stage will be switched off via two channels.
