Powertrain & Chassis Control Unit

CIU-100

CIU-100 is a cost-effective auxiliary processing unit for general purpose control applications. The CIU-100 provides a powerful 128MHz processing platform with 1kHz sampling of analogue input channels and actuation of high/low side drive stage pairs. A PowerPC processor provides the processing resource for application code which may be autocoded from Matlab/Simulink using our GDE and reprogrammed using the System Monitor application tool.

The unit includes three CAN interfaces for communication with System Monitor, the host ECU and other CAN linked system devices.

The CIU-100 can be used as a stand-alone control unit with a direct CAN connection to System Monitor for programming and configuration or could make an ideal companion to one of our ECUs.
