USB Relay Control Module

The LCUS-1 module connects to a USB port and provides a software-controlled relay switch for external circuits. It is intended for hobbyists, engineers or automation projects that need simple on-off control of low-voltage devices from a computer. No additional drivers are mentioned in the supplied data.

Practical Limits of USB-Powered Relay Operation

The board draws its operating power from the USB bus, so the available coil current is limited by the host port's rated output. Switching higher-voltage or higher-current loads requires an external power source and appropriate isolation. The single relay channel supports only one independent circuit at a time.
