{"product_id":"siemens-3rt1926-2cg21-time-relay-module","title":"Siemens 3RT1926-2CG21 Time Relay Module","description":"\u003cdiv\u003e\u003cp\u003eSiemens SIRIUS 3RT1926-2CG21 is a compact, two-wire solid-state timing relay that mounts directly onto Siemens contactors in the S0 to S3 size range, adding a precise ON-delay to a control circuit. It accepts an AC or DC supply from 24 to 66 V and provides a configurable delay of 0.5 seconds to 10 seconds before energising the contactor coil, using a semiconductor output to drive the coil rather than a mechanical contact. Wiring is accomplished via two pins that connect to the contactor’s coil terminals A1 and A2 on top of the relay block, enabling a tidy, single-block assembly. The CG21 variant is the ON-delay version and includes a varistor for surge protection to help tolerate transient voltage spikes in industrial environments. As part of Siemens’ SIRIUS timing family, this module is designed for installation in control panels and sequencing applications where a compact, reliable timing element is required without a separate relay, supporting simple integration with existing 3RT contactors and standard control wiring.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268109684970,"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-3rt1926-2cg21-time-relay-module","provider":"GTG Hardware","version":"1.0","type":"link"}
