The built-in optocoupler creates a complete electrical barrier between your control circuit and the load side, so voltage spikes from motors, solenoids, or AC appliances never reach your precious MCU. With a max load rating of AC 250V\/10A and DC 30V\/10A, you can confidently switch everything from LED strips and fans to pumps and home automation relays.\u003c\/p\u003e\u003cp\u003eDesigned for makers, students, and professional prototypers alike, this module slots straight into your breadboard or project enclosure without any additional components. Whether you are building a smart home switch, an automated irrigation controller, or an industrial prototype, the plug-and-play screw terminals and standard 3-pin header make wiring fast and foolproof. The status LED gives you instant visual feedback on relay state — no guesswork during debugging.\u003c\/p\u003e\u003cp\u003eSold by \u003cstrong\u003eamiciKart\u003c\/strong\u003e, a trusted electronics components vendor based in Noida.
