Parallel Port Relay Board - Kit or Assembled

Do you have an old PC lying around the house which absolutely no one wants? Then you can convert it into a dedicated controller. Communicate with the real world via the parallel printer port on your PC. Simply connect printer cable from your  computer to the 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 9x/2000/ME/XP.  The kit is a boon to the Science Fair project, laboratory experimenter and so on.


  • Requires 12VDC Power Supply.
    (Need a Power Supply?)
  • Relay has Normally Open and Normally Closed Contacts rated for voltages 12VDC @ 10A, 125VAC @ 10A, or 250VAC @ 5Amps. (more info on how relays work)
