Using \u003cstrong\u003esolid state relays\u003c\/strong\u003e instead of mechanical contacts, it provides compact electronic switching for projects that need reliable multi-channel control. This \u003cstrong\u003e4-channel SSR module\u003c\/strong\u003e is ideal when you want to expand a microcontroller into a simple four-output controller for automation tasks, timed switching, or computer-controlled electronics builds.\u003c\/p\u003e","brand":"ShillehTek","offers":[{"title":"Default Title","offer_id":52709886820639,"sku":"NA169","price":10.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/4340\/8415\/files\/4-channel-5v-ssr-module-angle-01.jpg?v=1786597412","url":"https:\/\/shillehtek.com\/products\/4-channel-5v-ssr-module-arduino-esp32-raspberry","provider":"ShillehTek","version":"1.0","type":"link"}
