Prerequisites
•
Safety switch with cable, 7-wire
•
Safety switch with cable with male connector, M12, 8-pin
Construction
The safety switches are led individually to the control cabinet. The OSSDs of the safety
switches are connected in series there and evaluated by the evaluation unit. The Aux
outputs are individually connected to the programmable logic controller (PLC).
