The PMDX-109 is an 8-channel relay board for pins 2-9 of the PC's parallel port (or Smooth Stepper).

  • Optically isolated outputs for the 8 data bits on pins 2 through 9 of a parallel port
  • Can be used stand alone with a parallel port or with the SmoothStepper
  • Port connections can be made via a 26 pin ribbon cable, or using on board DB-25 female
  • Pass through connectors allow it to be connected between a host port and the PMDX-125 or PMDX-126 to supplement PMDX-125/126's second port
  • Requires a single  DC power source for operation. The PMDX-109 keeps this power source isolated from inputs and outputs.
  • Power is supplied via a two pin terminal strip and 5 volt or 24 volt versions are available.
  • Power to this board may be removed by emergency stop without killing power to the other boards in the system, thus making safety circuits simpler.
  • Outputs use individual two pin terminal strips and are fully isolated from the parallel port and from each other
  • Outputs are electromechanical relays rated for 10 amperes at 120 VAC or  240 VAC, or 5 amperes at up to 30 VDC.
  • Outputs can provide isolated "switch closures" to control PLCs, other larger relays, or solenoids.
  • Outputs protected against spikes when turning off inductive loads such as relays
  • Outputs default to off condition if connection to parallel port is removed or if power is lost
  • Supports optional "Charge Pump" safety feature on pin 17
  • On-board LED's for power and for each input signal status
