Description
This is Four Channel relay board controlled by computer USB port. The USB relay board is with 4 SPDT relays rated up to 10A each. You may control devices 220V / 120V (up to 4) directly with one such relay unit. It is fully powered by the computer USB port. Suitable for home automation applications, hobby projects, industrial automation. The free software allows to control relays manually, create timers (weekly and calendar) and multi-vibrators, use date and time for alarms or control from command line. We provide software examples in Lab-view, .NET, Java, Borland C++, Python.

Additional information
This is relay board with 4 SPDT Relays controlled from USB port of your computer. The main purpose of this USB relay module is to help you building projects regarding robotics and home automation (demotic). You may control different electrical devices like home lights, DC motors, pneumatic cylinders, lasers and so on. Each such board requires one USB port. The more USB ports you have the more such relay units you may connect and control.
Each such USB relay board is shown as separate virtual com port (VCP) on your PC. The relay module outputs are controlled by FT245RL. It has 8 bit data output register (this device use only 4 of them). When data is sent to the register the outputs are set. If you are software developer – be sure “Synchronous Bit-Bang Mode” is selected! FTDI provides Bit-Bang Mode documentation. See this. The USB relay card can not be controlled directly via COM port – you need to download our DRM Software to control the device. The USB relay unit can not work without PC. Only one such device can be supplied from single USB port. If you want to supply many such devices you need USB HUB with extra power supply.
