IO-CAB is a cabin function controller used for windshield wipers, lamps, and solenoids. It utilizes slave modules for signal collection in a CAN network. It controls small to medium-power electric motors and serves as a generic module for high-current utilities. It is associated with the OMNIA steering wheel controls for the activation of typical functions such as windshield wipers, lamps, and more. All inputs and outputs are equipped with diagnostics and are monitored via the CAN-bus. It can be programmed in C language and IEC 61131 using the VT3 development tool.
