  • Update Rate: Up to 2000Hz.
  • USB connection to a Windows PC. No external programmer is required.
  • 50x RGB LED Indicators.
  • Free and easy to use configuration software.
  • 9-Axis IMU


  • 16 x 0-27V analogue/digital. inputs w/ frequency measurement.
  • Analogue inputs, which can also serve as digital inputs.
  • Measurement Range: Each input can measure between 0V-25V
  • Measurement Resolution: 16-Bit, or 0.001V
  • Fully protected for input voltages from -24V to 40V.
  • Integrated Software Selectable 10K Pull up/down resistors allow for positive and ground switching.
  • Inputs can be configured as Momentary or Latched, allowing for different types of switches to be used.
  • Hysteresis voltage can be added for extra resilience to voltage noise.
  • Frequency Measurement up to 300Hz with automatic triggering.
  • Software defined filters.


  • 4x High/Low side, reverse current blocking outputs capable of supplying 30A continuous and 100A Peak
  • 6x High/Low side, reverse current blocking outputs capable of supplying 20A continuous and 80A Peak
  • 18x High/Low side outputs capable of supplying 20A continuous and 80A Peak.
  • 200A combined output maximum current
  • Protection: Each output is overcurrent, overtemperature, load dump and reverse polarity protected.
  • Output Current Control Steps: 100mA (0.1A).
  • Output Current Measurement resolution: 3mA
  • Peak fuse and High fuse thresholds can be set to allow for inrush current.
  • Trip Mode can be set to Instant (output trips immediately if the current exceeds the threshold) or Normal (acts like a normal physical fuse and allows short current spikes).
  • Outputs can be configured to stay on for a specified time after the input is removed, useful for radiator fans or water pumps.
  • Outputs can be retried multiple times after an over-current event is detected.
  • 1000Hz PWM on each output, with variable duty cycle mapping.
  • Soft start on each output for smoother turn on of devices.
  • Advanced logic functions can be made to control the output as desired.

Live Data Analysis

  • View all PDM data in real-time.
  • Data can be viewed in numerical form, or in a graphical format.
  • Detect errors and anomalies quickly and efficiently.
  • Ensure that the system is working as intended before deploying the PDM in the vehicle.


  • Each Output can be switched with a user defined logic. function, allowing for incredibly flexibility with control.
  • Logical Operators: AND, OR, NOR, XOR, NAND, NOR, >, >=, <, <=, Equal, Not Equal.
  • Global Cut Off Function can be set to turn off every output at once in an emergency.
  • Global Reset Function can be set to re-enable any tripped outputs in real-time.
  • Generic Functions can be set to allow for more complicated nesting of functions.

Data Logging

  • 128Mb of onboard flash storage for logging PDM data
  • 0.1Hz to 50Hz data logging rate.
  • Data can be downloaded and graphed via the Hardwire Electronics PDM configuration software.
  • Data can be exported as a .csv file for use in external data analysis software.
  • Log data based on a logical condition to capture specific events.

Maths Channels

  • Real Time Maths Channels can be used to convert data on-the-fly.
  • Basic Operations: Addition, Subtraction, Division, Modulus.
  • Bit-wise Operations: AND, OR, XOR, Left Shift, Right Shift.
  • Advanced Operations: Choose, Min, Max.
