PC Parallel Port Interface Kit
each rated 12VDC/10A or 240VAC/5A
Includes PCB and all components
Convert an old PC into a dedicated controller. Communicate with the real world via the parallel printer port on your PC. Simply connect printer cable from computer to Centronics connector on relay board. There are 8 relays each capable of switching 12VDC/10A or 240VAC/5A. Each relay has an LED to indicate when it is operated. We provide two sets of complete, stand-alone software to control the relays: one works under DOS so you can write your own batch files to control individual relays, the other under Windows.
You need to install a Windows version no later than Win2K or Win ME on the target computer.
