A PDM (Power Distribution Module) is a device used to replace conventional relays and fuses in a vehicle electrical system. The HW Electronics PDM accepts inputs from physical switches, analogue voltages, or the CAN bus. With a rating of up to 200Amps of current spread across the 28 programmable outputs, it can easily provide power to different electronical devices such as the starter, radiator fans, fuel pumps, water pumps, head lights, turn signals, YOU NAME IT.

 

The current being drawn from each connected device is continuously monitored. If the measured current is too high due to a fault, the PDM switches off the respective output to prevent further damage to the wiring loom or the connected device. The PDM can then retry the output to see if the fault has cleared.

 

If you select from the dropdown you would like to include programming for vehicle, we will contact you to set up a meeting to discuss your specific needs. After the meeting, we will program the PDM to match your needs and provide a wiring aid to simplify your installation! 

 

Specialty features we have programmed include (but not limited to): neutral safety with engine RPM starter lockout, driving solenoids, automatically controlling fans and pumps based on temperatures, CAN BUS interfacing, Multifuction buttons for turn signals, 4-ways and brake lights, exc. (This unit is EXTREMELY flexible, in most cases affording you the peace of mind for changes later on WITHOUT the need of rewiring!)

PriceFrom $1,900.00
  • Advantages Over Fuses and Relays

    • Greatly simplifies system wiring and reduces system component count.

    • Reduces the weight of the electrical system.

    • Provides increased reliability over traditional systems using mechanical relays. 

    • Solid state technology removes the problem of relay contact corrosion and relay bouncing in vibration heavy applications.

    • Smart features such as indicator and wiper motor modes remove the need for extra control units.

    • Current draw can be monitored and logged to pre-emptively detect faults.

    Inputs

    • Type: 16 Analogue inputs, which can also serve as digital inputs

    • Measurement Range: Each input can measure between 0V-6V

    • Measurement Resolution: 10-Bit, or 0.01V

    • Protection: Fully protected for input voltages from -24V to 40V 

    • Added Features: Current sourcing for ground switch detection. Configure as active high or low. Configurable Hysteresis voltage. Latching or momentary operation.

    Outputs

     

    • Type: 25 High side outputs 80A peak, 20A continuous.

    • Combined: 180A combined output maximum current

    • Output Current Control Steps: 100mA (0.1A)

    • Protection: Each output is overcurrent, overtemperature, load dump and reverse polarity protected.

    • 5V: One 5V, 500mA output for supplying external sensors/Hardwire Electronics CAN Keypad

    • Added Features: Outputs can be configured to stay on for a specified time after the input is removed, useful for thermo-fans. Outputs can be retried multiple times after an over-current event is detected.
