The PMDX-105 is a 4-channel signal isolator/translator board

  • Can be used for adapting breakout board inputs or outputs to otherwise incompatible signals 
  • Translator inputs work with voltage sourcing signals and sensors
  • Allows PMDX (and other) breakout boards to operate with PNP style sensors
  • Inputs tolerate up to 24 volts DC and can operate from 5 volt logic signals
  • Provides optical isolation of signals
  • Response time of 2 milliseconds or less (not suitable for step and direction signals)
  • Outputs provide isolated MOSFET "switch closures" to "ground"
  • Output current of up to 150 mA 
  • Outputs can provide pull-up resistors to reference voltage source of 24 VDC or less
  • Output voltage range is 0 to 50 volts DC if pull-up voltage is not used
  • Clamp style screw terminal strips for inputs and outputs allow use with any breakout board
  • No power source other than signals is required for operation
  • Can work with the PMDX-122, PMDX-126, PMDX-412, PMDX-416 or PMDX-424.
