Product description

The Moeller ESR4-NO-31 is an E-stop safety relay for E-stop and safety gate monitoring in machine and plant controls. 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.

The 24 V AC/DC control voltage and the compact 22.5 mm DIN rail housing make the unit universally usable. Screw terminals, wire size 28–14 AWG. Status LEDs for POWER and channels K1/K2 allow quick diagnostics.

Tested: we have tested this item and it is fully functional. Clean used part with at most light cosmetic traces. Delivered exactly as shown.
