Product Description
Hardwire Electronics PDM35 V2 Module
The PDM35 V2 is the newest PDM (Power Distribution Module) from Hardwire Electronics, a natural update to the outgoing PDM15/25 V1. With new features such as High/Low side outputs, 9 Axis IMU, improved CAN bus and more. The PDM35 uses 10 of the input pins on the PDM25 V2 as dual use IO.
A PDM is a device used to replace conventional relays and fuses in a vehicle electrical system. The Hardwire Electronics PDM35 takes inputs from physical switches, analogue voltages, or the CAN bus, and provides power to different electronic devices such as radiator fans, fuel pumps and head lights. 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.

|
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. |
