Hardwire Electronics PDM 25

The PDM 25 is our top of the line PDM, offering all the features of the PDM 15 but adding 10 additional outputs for a total of 25 full configurable and programmable outputs. The PDM 25 has the same 2 canbus networks for easy integration with other canbus enabled devices and can support a total of 180A of current in the electrical system. Use the canbus networks to trigger outputs in the PDM based on data streaming from the ECU or other canbus devices, then send canbus data from the PDM to your digital dash or datalogger to allow understand the current status of your car's electrical system. The PDM 25 includes the Deutch connectors and pins to get set up and running. Contact us to have your PDM preconfigured before shipping.

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.
