PDM16M

The MoTeC Output Power Distribution Module is designed to provide electronically switched power to the vehicle's various electrical systems 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 switching requirements while increasing reliability.

Features

  • Each output is protected against overcurrent, short circuit and thermal overload
  • Outputs programmable in 1 A steps and controllable through a combination of switching inputs, CAN messages and logic functions
  • Performs up to 200 logical operations and functions that can be used to selectively shut down systems
  • Provides complete diagnostic information via CAN

    Wiring

    CAN Wiring
    The PDM is connected to the CAN bus. Make sure the wiring complies with CAN requirements and that the CAN bus has at least a 100R termination resistor. More information can be found in the user manual located in the downloads below

    To communicate with the PC, a CAN connector must be connected to the CAN bus. To connect the PDM directly to the CAN connector, connect according to the following table.

    Wiring example
    Wire gauge

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