Elecbee 1-Channel 5V USB Relay Module HID Driverless Programmable Switch 10A AC/DC Computer Control for Smart Automation

The Elecbee 1-Channel 5V USB Relay Module is a programmable HID driverless relay control board designed for computer-controlled switching, industrial automation, smart home systems, and centralized power management applications. Featuring USB HID communication technology, this relay module supports plug-and-play operation without requiring additional drivers under compatible Windows operating systems.

The module supports DC 5V input and provides reliable switching control for AC 250V 10A or DC 30V 10A electrical loads. Integrated with a high-performance USB control chipset and ULN2803 relay driver IC, the board delivers stable relay operation for automation systems, test equipment, timing control, and embedded computer management projects.

This programmable relay board is suitable for smart home automation, industrial equipment power control, intelligent greenhouse systems, hotel electrical management, Internet cafe timing systems, street light management, IoT control systems, and laboratory automation projects.

The onboard square USB interface provides stable connectivity, while dual power input options through the terminal block and DC power socket offer flexible integration into different system architectures. The relay state can remain stored even after USB disconnection or computer shutdown when external power is connected.
