This PC printer (parallel) port relay board provides independently programmable real-time control for each of the eight onboard relays.

Relay outputs can be used to automatically turn On/Off lights, motors & other devices around the home, office, laboratory or factory. The software interface is compatible with Windows 7 (32-bit)/Vista/XP/ME/2000/NT/9x and allows you to program and save an infinite number of On/Off sequences. Alternatively, you can write your own software with a DLL from logix4u (see EPE Magazine Tutorial for more details).

NB If this board is powered up and connected to the computer, all of the relays will momentarily turn on when the PC first boots up. If this is a problem, please look at our 8-Channel Serial Port Isolated IO Relay Controller instead.

  • Can be used with any PC parallel port on a 286 upward (remember those?)
  • Each channel has a relay output
  • LED relay status indicator for each relay
  • For a BOXED version of the project see Order Code 3165
