It supports time-delayed ON functions up to 100 seconds across three timing ranges and is part of ABB's TEF4 family, including TEF4-OFF and TEF4-S-ON variants. The coil version commonly available for this timer is 240 V AC (catalog 1SBN020112R1000), with a direct plug-in connection to the coil terminals, enabling compact, integrated timing without external wiring. Typically used to control sequencing or start-up delays in automation applications where a precise on-delay is required for actuators, valves, or relays, this TEF4-ON accessory ensures predictable activation timing and helps coordinate machine start-up or stop processes in a variety of control circuits. It is documented in ABB literature and catalogues, including ABB's official literature and distributor listings, as a plug-in timing accessory for TEF4 relays. \u003c\/p\u003e\u003c\/div\u003e","brand":"ABB","offers":[{"title":"New","offer_id":51656710062382,"sku":null,"price":29.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_b05e10e8-9866-4cfe-868b-4ef6eb8a5570.jpg?v=1769462844","url":"https:\/\/plgautomation.com\/products\/abb-tef4-on-4-channel-industrial-safety-relay-module","provider":"PLG Automation ","version":"1.0","type":"link"}
