Haldex Controller

 

The Haldex Controller can be used for all 4 Motion vehicles, original or Standalone.
All connections are Plug and Play except for the standalone functions.
The controller works completely standalone so it does not need the App to function.
When the controller is powered up it starts running the program that was last used.
All settings made in the App are saved to the internal memory of the controller.
The App is used to display the status and change mode and settings.

The Controller can use the input signals from the CAN-BUS or Analog signals
Brake           CAN-BUS and Analog 12 volt signal
Speed          CAN-BUS and Analog VSS signal
Throttle        CAN-BUS and Analog 5 volt signal
Boost           CAN-BUS and Analog 5 volt signal
Handbrake   Analog Ground signal
RPM             from CAN-BUS only

The Controller has a RPM output for converting CAN-BUS RPM to Analog.
