Power Distribution Modules

MoTeC's 2009 release of the Power Distribution Module (PDM) 15 and 30 output models has been exactly what the racing industry has needed for quite some time. The PDM is a microprocessor controlled power distribution center for your race car. It takes the place of all of your relays, timers, and fuses all in one small package weighing less than 1 pound. There are multiple 20 amp outputs and multiple 8 amp outputs which can be ganged together to give up to 115 amps of service. The outputs are controlled by user configurable conditions within the control software for the unit. Conditions can be based on the hardwired logic inputs to the unit or from other channels transmitted to the unit from another MoTeC CAN enabled device or both.

MoTeC Power Distribution Modules (PDM) are designed to replace conventional relays, fuses and circuit breakers by providing electronically switched power to the various electrical systems in the vehicle. This simplifies wiring and switch requirements, while increasing reliability.

Each PDM output is over-current protected and can be controlled via a combination of switch inputs, CAN messages and logic functions. In addition to performing simple functions such as flashing indicator lamps, the logic functions can be used to selectively turn off systems during low battery voltage or engine starting.

The PDMs also provide full diagnostic information, including output currents and error status that can be monitored on a PC or transmitted via CAN to a display or logging device.

The basic wiring arrangement for MoTeC PDMs is as follows:
