USB Relay 4 Channel Programmable Computer Control. Windows and Linux drivers.
Please note you need 12V Powersupply to operate this relay and not just the USB power.
This is USB controlled relay Board with 2 channels. It’s used the HID technology, so no need to install any driver in windows system and is easy to use.
There is also a application and the C++ develop library that you can use to integrate this module to your project.
This module can be used for the following:
1. Supply the application code
2. Supply C++ lib and dll for building your own project(include usb_relay_device.dll, usb_relay_device.lib, usb_relay_device.h)
My driver installation took about 10 minutes
Here is an example how to control the relay in command line.
CommandApp_USBRelay.exe [device id] [close / open] [relay nr]
Here is a screenshot of the Windows application.
