It features three safety contacts and a signal contact (41\/42) with normally-closed parallel contacts, enabling both safety switching and a diagnostic signaling function. The module operates from a 24 V AC\/DC supply and uses plug-in screw terminals with coding; conductors of 0.2–2.5 mm² are supported (including fine wire with ferrule 0.25–2.5 mm²). Cable lengths support long runs—up to 1,500 m with 1.5 mm² and 2,500 m with 2.5 mm²—and it is designed for installation in control cabinets to monitor safety devices such as E-stops, guard doors, safety solenoids, and AOPDs.\u003c\/p\u003e\u003c\/div\u003e","brand":"Schmersal","offers":[{"title":"New","offer_id":46283991613674,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-021.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/schmersal-srb-e-301mc-safety-relay-with-monitoring-contacts","provider":"GTG Hardware","version":"1.0","type":"link"}
