AS3074KT - 8-Channel PC Controlled Relay Board

Ability Level 3: IntermediateProduct Formats Available: Pre-Assembled Module (AS) or
Self-Assembly Electronic Kit ( Soldering Required)

This PC printer (parallel) port relay board provides independently programmable real-time control for each of the eight onboard mains rated 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 http://logix4u.net/parallel-port.

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 thoseΩ)
  • Each channel has a relay output
  • LED relay status indicator for each relay
  • For a BOXED version of the project see Order Code 3165
