Description
This is relay card with eight SPDT relays which is controlled via PC USB port. We have created flexible software for this USB relay board, that allows you to make simple automation project or control from command line. We provide various examples in .NET, Java, VB6, BCB6, Lab-view, Python and others. Android app is also available.
This is relay board with 8 SPDT relays which is controlled via USB protocol. The main purpose of this relay board is to help you building projects regarding robotics and home automation. You may control different electrical devices like lights, DC motors, pneumatic cylinders, lasers and so on. Hints for creating user application in different platforms (Visual C++, Borland C++ Builder, Visual Basic and so on) are provided. Each such board require one USB port. The more USB ports you have the more Relay boards you may connect. We have Windows examples for VB6, BCB6, Java (net-beans), VB.NET 2010 Express, C++.NET 2010 Express – please contact with us for more details.
