It offers four normally open contacts: two instantaneous NO outputs and two NO outputs with a time delay, all driven from a 24 V DC coil (Us = 24 V DC) via a screw-terminal connection. The unit supports a time-delay range of 0.5 to 30 seconds and is intended for panel installation where safeguarding devices such as interlocks or emergency-stop circuits must reliably interrupt the actuation path to stop machinery when safety conditions are breached.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268157722858,"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-3sk1121-1cb42-industrial-safety-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
