The 12V 4-channel relay module with optocoupler is a reliable and efficient switching solution designed to control high-voltage AC and DC appliances using a low-voltage 12V signal. Each of the four relays can handle loads up to 10A at 250V AC or 10A at 30V DC, making it suitable for a wide range of applications such as home automation systems, industrial equipment control, and IoT-based projects.
The integrated optocoupler isolation provides enhanced protection by preventing voltage spikes and electrical noise from affecting sensitive control circuits. Additionally, the module features LED indicators for each channel to display relay activity and comes with screw terminal connectors for secure, hassle-free wiring, making it an excellent choice for both beginners and professionals.
