Pluggable module for extended control and diagnostic functions

The CDM-A16 module is a plug-in controller for power distribution systems in vehicles and extends them with programmable control and diagnostic functions.

The module provides up to 16 channels for fuse status monitoring and peak-and-hold relay activation. The peak-and-hold function reduces heat generation in the relay coil, thus extending the possible operating time.

The vertical design of the module reduces the required space and thus enables the integration of additional relays and fuses into the power distribution system.



  • Fuse status monitoring and relay control with peak-and hold function
  • CAN communication with multiple buses, enabling gateway functionality (J1939, RAW CAN bus protocols)
  • Logic processing of vehicle functions, programmed with WEcontrol Designer, an IEC61131-3 programming environment (FBD, ST, SFC, etc.)
  • Sensor management (current, temperature, etc.) with 5 V supply and sensor acquisition via 8 analog inputs
  • Direct load control through 4 digital outputs (2 A / PWM)
