It can be wired single- or dual-channel; in dual-channel wiring with feedback loop (Y1\/Y2\/Y3) it reaches the highest control category 4 per EN 954-1. The three positively driven safety contacts (NO) safely switch off the working circuit; the additional NC serves as a signaling contact for the higher-level control.\u003c\/p\u003e\u003cp class=\"dw-text\"\u003eThe 24 V AC\/DC control voltage and the compact 22.5 mm DIN rail housing make the unit universally usable.
