8 Channel 12V Relay Module with Optocoupler (8 Relay Module)

The 8 Channel 12V Relay Module with Optocoupler is a high-capacity relay switching board designed to control multiple high-voltage or high-current loads using low-voltage digital control signals. Each relay channel features onboard optocoupler isolation, providing electrical separation between the control circuit and the load for enhanced safety and noise immunity. The module is ideal for industrial automation, control panels, home automation, and multi-device switching applications.
