This iU-2RD 2 channel USB relay board is very useful for computer operated automation
and other controlling projects. USB provides very easy connectivity with the board.
The board is a CDC device so it will appear as a COM port to the PC. So now it can
be used even with a simple serial terminal utility like Hyper Terminal or PUTTY or any
other serial terminal software. You can also use higher level languages like VB, C#,
VC++ to have your own program for controlling the 2 channel USB relay board iU-2RD.
You can not only monitor various analog or digital signals from various kind of
Temperature, Pressure, Magnetic , Light & Gas sensors. It can also used to monitor
mechanical switches for manual inputs to your system.
Based on sensor inputs to the card, you can control the outputs also. Say for example
– to make a temperature controller, get the input from temperature sensor and based
on inputs you can decide if a fan has to be operated or not. You can connect
temperature sensor to ADC inputs and a fan to the one of the relay. That is all. You
have complete Temperature controller !
Like the above example, you can use this 2 channel USB relay board iU-2RD for many other projects.
