The 4-Channel 12V Relay Module with Optocoupler is a reliable switching board designed to control high-voltage AC and DC devices using a 12V control signal. Each relay supports up to 10A at 250V AC or 30V DC, making it suitable for applications such as home automation, industrial equipment control, motor drivers, and smart device projects.
With optocoupler isolation, the module ensures stable operation and protects sensitive control circuitry from voltage spikes and interference. Each channel includes an LED indicator for relay status monitoring, and screw terminal connectors make wiring secure and convenient.
