This relay is energized by a 12-volt direct current control signal and is designed to switch loads up to 4 amps on its contacts, making it suitable for interfacing low-voltage control logic with higher-current equipment in industrial automation and control panels. The HC12-3 provides galvanic isolation between the control and load circuits, helping protect control electronics and supporting reliable operation in typical industrial environments. Use it to convert a 12 V control signal into a separate, switchable contact path for loads that stay within the 4 A rating. When selecting this relay, verify that the coil voltage matches your control supply and that the connected load current does not exceed 4 A, with appropriate wiring practices and any required protection to maintain safe operation over its service life.\u003c\/p\u003e\u003c\/div\u003e","brand":"POWER","offers":[{"title":"New","offer_id":46285665239274,"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-025.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/industrial-hc12-3-dc-coil-relay-12vdc-4a-contact-rating","provider":"GTG Hardware","version":"1.0","type":"link"}
