5V 8-Channel Relay Module with Optocoupler

The 5V 8-Channel Relay Module is a reliable relay interface board designed to control up to eight high-voltage AC or DC devices using low-voltage control signals from microcontrollers, PLCs, and automation systems. It provides electrical isolation between the control circuitry and the connected loads, ensuring safe and dependable operation in a wide range of automation and embedded applications.

Each relay channel can switch loads up to 250V AC at 10A or 30V DC at 10A, making the module suitable for controlling lights, motors, pumps, solenoids, and other electrical equipment. It features selectable high-level or low-level triggering, LED status indicators for power and relay operation, screw terminal connections for secure wiring, and mounting holes for easy installation.
