It features four contacts—two normally open and two normally closed—driven by a 24 V DC coil, with screw terminals for straightforward wiring. This configuration makes it suitable as an interface\/expansion module within Siemens safety ecosystems, enabling reliable isolation between logic and final control elements and allowing safe interconnection of control circuits with safety relays. The device carries SIL 2 and PL c safety classifications, reflecting its use in safety-critical applications, and is marketed under the SIRIUS 3RQ1 family as a coupling relay for safety purposes, often employed to safely couple a controller to safety relays or sensors in automated systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268101853418,"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-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-3rq1000-1hb00-coupling-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
