A total of 34 output channels with a maximum steady state current capacity of 200A

Robust and Ultra Compact

Clear and Powerful Fully Graphical Logic Programming Software - Easy to read and follow with full logic simulation ability, complete operational logic schematics can be physically printed giving quick and easy reference material for engineers working on building or maintaining the vehicle wiring.

Inputs - 16 ON/OFF input channels; also capable of support 0-5v, Thermistor, Bi-polar and Frequency type signals when used in 'Slave Link' mode.

Slave Link - enables Life Racing ECU units to directly claim access to the PDU34A's input and output channels in order to receive data from or else control those channels with ultra low latency

Flexible outputs - 10x flexible output drivers configurable to operate as high power High side power switching, as Half-bridge or paired into 5x Full-bridges, these 10 outputs can also be configured to operate as low-side PWM drivers.

The PDU34A's combined flexibility allows racing vehicle system designers the freedom to use these robust PDU output channels to perform high speed control tasks managed by any Life Racing ECU. Some examples of are, direct closed loop power control of electric engine coolant pumps, fuel and oil pump power, VVT position actuators (both motors and solenoids), direct control of DBW systems.

The PDU34A is capable of configurable soft starting of electrical loads as well as closed loop current limitation, this can be used to reduce large short duration inrush current which can be generated when switching on large electrical loads such as high power radiator cooling fans.

Network Interfaces - 1x CAN 2.0b, 1x LIN (Custom Projects Only), 1x RS232C serial interface (Custom Projects Only). and a two port Ethernet switch

Advanced Power Management - the PDU34A can be user configured with options for simple on/off operation with the units main supply voltage. But is also capable of automatic wake/sleep operation which can be set to be triggered either by switching dedicated "wake" pin, or can be configured to wake on activation of inputs channels 12 to 16.

The wake and sleep operation of the unit can also be controlled by CAN bus 1 operation, wake on bus activity or upon receipt of a specific CAN message, all with fully user configurable address's and operational parameters as well as timeout settings for auto sleep.
