The module supports both high-level and low-level trigger modes, allowing flexible activation logic depending on the host controller or sensor polarity. An integrated optocoupler provides electrical isolation between the control input and the relay drive stage, helping to reduce interference and protect sensitive controller circuitry.\u003c\/p\u003e\u003cp\u003eThe relay output provides a common, normally open, and normally closed contact configuration suitable for switching external loads within the relay's rated limits. The board includes signal input, power supply and relay output terminals laid out for straightforward wiring and quick integration into prototyping or production systems. Status indication is provided by a visible LED on the board that illuminates when the relay is active, simplifying setup and troubleshooting.\u003c\/p\u003e\u003cp\u003eThis relay module is suitable for applications requiring a single isolated switching channel controlled by a 5V logic-level signal, and for users who need selectable trigger polarity and basic input-output isolation on a small footprint module.\u003c\/p\u003e","brand":"Electronic Service Center","offers":[{"title":"Default Title","offer_id":45564170993847,"sku":"214","price":10.0,"currency_code":"LYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/4010\/0279\/files\/IMG-9120.png?v=1766666830","url":"https:\/\/esclibya.com\/en-ly\/products\/5v-1-channel-high-low-level-trigger-relay-module-with-optocoupler","provider":"Electronic Service Center","version":"1.0","type":"link"}
