A relay module lets 3.3V or 5V logic switch real household-voltage loads, a lamp, a fan, a heater, without ever letting your controller's delicate GPIO pins touch dangerous voltage directly.\u003c\/p\u003e\u003cp\u003eOpto-isolation is the detail that matters here: an optical barrier physically separates your control circuit from the switched load circuit, so a fault on the high-voltage side cannot feed back and fry your controller.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e5V logic trigger, opto-isolated for real electrical safety\u003c\/li\u003e\n\u003cli\u003eSwitches high-current or high-voltage loads from a simple digital signal\u003c\/li\u003e\n\u003cli\u003eWorks with high or low trigger logic, compatible with virtually any controller\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe switching component behind our Digital Thermostat Demo, where it is the difference between a build that just displays a temperature and one that actually does something about it.\u003c\/p\u003e","brand":"Nexus Micro Labs","offers":[{"title":"5V","offer_id":52881154048312,"sku":"TML-PWR-5V-RELAY-MODULE-01","price":95.0,"currency_code":"THB","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1012\/8716\/6264\/files\/relay-spec-callout-final.png?v=1788483047","url":"https:\/\/nexusmicrolabs.com\/en\/products\/5v-relay-module-opto-isolated-1-channel","provider":"Nexus Micro Labs","version":"1.0","type":"link"}
