Advantages Over Fuses and Relays

• Greatly simplifies system wiring and reduces system component count, saving you money overall when labour/ time is accounted for. 

• 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.

• CAN bus communication allows your PDM to send/receive data from other CAN bus devices in the vehicle, such as the vehicle ECU. This paves way for advanced control/ safety strategies such as automatic engine cut offs, fuel pump cut offs, radiator fan control and more. 

• Easy integration with popular CAN bus keypads, improving system reliability and functionality.

Inputs

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

• Each input can measure voltages between 0-28V, independent of the battery voltage.

• Measurement Resolution: 10-Bit, or 0.01V

Outputs

• Type: 

  • 19 high side outputs 80A peak, 20A continuous. 
  • 4 hybrid high/low side outputs 80A peak, 20A continuous.
  • 2 reverse current protected outputs, for use with wiper motors. 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.

• PWM: Each output can be Pulse Width Modulated based on a user defined variable. This can limit the speed of radiator fans, fuel pumps, and dim lights.

• Soft Start: PWM soft start can be enabled on outputs to limit inrush current.

• 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.
