Overview
The ABB PC D230 A, product number 3BHE022291R0101, is a Communication Control Measurement (CCM) module designed for ABB UNITROL 6000 X-power excitation systems. It forms part of the PEC80 control equipment and supports communication, signal acquisition and control measurement functions within the excitation system. Furthermore, its exact product identification is important when selecting a replacement or checking an installed assembly.
Function and Signal Configuration
The PC D230 A handles communication and measurement functions within the excitation control system. Its documented configuration includes:
- Four Ethernet switch ports and one RS232 port.
- Three optical couplings in an optical interface module.
- Six optically isolated digital inputs rated at 24 V.
- Three digital outputs, including two relay outputs and one galvanically isolated output.
- Four analog measurement inputs for voltage and current signals.
- Two galvanically isolated analog outputs.
- Four status LEDs for system monitoring.
Furthermore, the module provides measurement communication between the generator and the electrical network. These signals support the associated excitation system’s monitoring and control functions.

System Application and Replacement
The PC D230 A works as a communication and measurement component in the ABB UNITROL excitation platform. Meanwhile, the AC 800PEC controller performs the main generator voltage regulation, field current control, monitoring and protection functions. These are separate modules with different responsibilities.
Therefore, maintenance teams should identify the installed module by its complete product ID before ordering a replacement. In addition, hardware and software compatibility with the existing UNITROL system should be checked before installing an alternative assembly.
