When the input is energized, the timer begins counting and, after the programmed delay, the output changes state to drive the connected load. It is specified for AC operation at 200–240 V and 50\/60 Hz, making it compatible with standard mains supplies in many regions. Typical applications include motor-start sequencing, lighting delays, and process-control steps where a precise, repeatable delay after an input event is required. The device is part of Siemens' line of timer relays and supports typical control-system wiring practices, enabling straightforward integration with compatible Siemens hardware and control panels. Once installed, the 7PU4040-3AN20 delivers consistent on-delay performance across cycles, helping to coordinate sequential actions, prevent premature activation, and stabilize timed-control sequences in industrial environments.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268703015146,"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-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-7pu4040-3an20-on-delay-timer","provider":"GTG Hardware","version":"1.0","type":"link"}
