PDM32
VISIÓN GENERAL
MoTeC’s 32 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.
CARATERISTICAS
- 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
ESPECIFICACIONES
Inputs
- 23 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)
- 24 x 8 A outputs: 8 A continuous, 60 A transient (typical)
Communications
- 1 x CAN
Operating Voltage
- 30 V max
Ingress Protection (IP) Rating
- Rubber seal on lid and connectors, conformal coating on PCB
- The device is rated to IP67
IP rating is dependant upon the user ensuring that the connector entries are waterproof, which, as a minimum, requires all unused wire cavities on the connector to be plugged.

CABLEADO
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 |
|---|---|---|---|
| CAN Lo | 4 | Green | |
| CAN Hi | 5 | White | |
| 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 minimise 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.
DIMENSIONES Y MONTAJES
