Up for auction is a new Motec PDM30 Power Distribution Module (PDM). I purchased it a few years ago for a project that never came to be. It is unused and has never been powered up. MSRP is $3270.00. My starting price is much lower. Comes with what you see in the photos. It's a current product with full documentation, software downloads, etc. on Motec's site. This is their description:

MoTeC's 30 output Power Distribution Module is designed to provide electronically switched power to the various electrical systems in the vehicle such as motors, lights, solenoids, and electronic devices such as ECUs and data acquisition systems.

The module replaces conventional relays, fuses and circuit breakers to simplify wiring and switch requirements, while increasing reliability.

  • Each output is over-current, short circuit and thermal overload protected
  • Outputs programmable in 1 A steps and controllable via a combination of switch inputs, CAN messages and logic functions
  • Performs up to 200 logic operations and functions that can be used to selectively turn off systems
  • Provides full diagnostic information via CAN
Inputs
  • 16 x switch inputs: range 0 to 51 V, resolution 0.2 V
Outputs
  • 8 x 20 A outputs: 20 A continuous, 115 A transient (typical)
  • 22 x 8 A outputs: 8 A continuous, 60 A transient (typical)
Communications
  • 1 x CAN
Operating Voltage
  • 30 V max
Ingress Protection (IP) Rating
  • Conformal coating on PCB
Physical
  • 1 x 34 and 1 x 26 pin waterproof connectors, 1 x M6 stud
  • Case size 107.5 x 127.5 x 38.7 mm
  • Weight 270 grams

Latest software can be found in downloads below

PDM Manager software is used for:

  • Configuring all inputs, outputs, CAN messages and conditions
  • Monitoring all channel values
  • Output testing
  • Firmware updating
CAN Wiring
The PDM is wired onto the CAN bus. Please ensure wiring is according to CAN requirements and the CAN bus has at least one 100R terminating resistor. More information can be found in the user manual located in the downloads below

To communicate to the PC, a CAN connector must be wired into the CAN bus. To connect the PDM directly to the CAN connector, wire according to the following table.

PDM Pin PDM Name CAN Connector Pin CAN Connector Wire
B25 CAN Lo 4 Green
B26 CAN Hi 5 White
A28 0 V 1 Black
Example Wiring
Wire Gauges

Suitable wire gauges are 24# to 20# for the 8 A outputs and 20# to 16# for the 20 A outputs. The wire gauge must be chosen to suit the current consumed by the connected device and to ensure that the voltage drop is acceptable. In a long run it may be necessary to use a heavier gauge wire to minimize voltage drop. The wire gauge must also be compatible with the connector pin; using a smaller than recommended wire gauge may result in a poor crimp.

Measurements in mm.

The product provides through holes for mounting. See drawing for details.

Recommended mounting torque value is 5 Nm. The torque value must not exceed 5.5 Nm.
