2 Channel 12V Relay Module with Optocoupler (Dual Relay Module)

The 2 Channel 12V Relay Module with Optocoupler is a dual relay switching board designed to control high-voltage or high-current loads using low-voltage digital control signals. Featuring onboard optocoupler isolation, it provides electrical separation between the control and load circuits for enhanced safety and noise immunity. The module enables independent control of two relays, making it ideal for automation, industrial control, home automation, and embedded system applications.
