Description
Product Overview
The ABB PCD231B101 3BHE025541R0101 is a Converter Control Interface (CCI) module identified in ABB product documentation as PC D231 B: PEC80-CCI. It belongs to the power-electronics control hardware used in ABB UNITROL 6000 X-power static excitation systems. Its role is to provide an interface between the PEC80 control platform and converter-control equipment. This is a specialized excitation-system component, not a general-purpose PLC processor or standard analog I/O module.
In a static excitation system, the control platform regulates generator excitation while converter hardware controls the electrical power delivered to the generator field. The CCI module forms part of the interface between these control and power-conversion functions. Depending on the specific system design, associated hardware and signal paths may include optical connections and thyristor converter control. The exact channel count, connector assignments, and firing-interface details should be confirmed from the applicable ABB system drawings and module documentation rather than inferred from reseller descriptions.
For maintenance and procurement teams, the critical issue is matching the installed hardware and excitation-system configuration. Confirm the full part number, 3BHE025541R0101, and the PCD231B101 designation, then compare board revision, connectors, mounting arrangement, and associated PEC80 hardware. ABB product data lists dimensions of 373 × 73.5 × 142 mm and a net weight of 1.43 kg. Other electrical specifications—including supply voltage, power consumption, and environmental limits—should be verified against the applicable manufacturer documentation before being used for acceptance testing.
Product Introduction
The PCD231B101 is intended for use in compatible ABB PEC80 converter-control arrangements associated with static generator excitation. It is relevant to maintenance programs, outage spares, and repair work where the original CCI hardware must be restored without changing the established excitation-system design. Correct operation depends on the surrounding controller, converter hardware, firmware, configuration, and interface connections.
When sourcing a replacement, request photographs of the complete nameplate, connectors, and module assembly. Confirm whether the unit is new, unused surplus, repaired, or refurbished, and obtain the available inspection and test records. Before installation, preserve the original wiring and configuration information and follow the plant’s approved isolation and commissioning procedures. A module that passes a basic power-on check has not necessarily been verified for its intended converter-control application.

Frequently Asked Questions
Q1: What is the ABB PCD231B101 used for?
It is a Converter Control Interface module used in compatible ABB UNITROL 6000 X-power static excitation systems. ABB identifies its catalog designation as PC D231 B: -CCI.
Q2: What is the full ABB part number?
The associated order number is 3BHE025541R0101. Check both the designation and the complete order number when ordering a replacement.
Q3: Is the a standard PLC communication module?
No. Its documented identity is a converter-control interface for hardware. It should not be treated as a general-purpose PLC communication or I/O module.
Q4: Can it be replaced with a PCD232?
Do not assume interchangeability. The PCD232, part number 3BHE022293R0101, is cataloged as a combined input/output module, whereas the is identified as a -CCI. Their roles differ.
Q5: What supply voltage does the require?
The cited ABB catalog record does not confirm the required supply voltage. Check the module documentation and excitation-cabinet drawings rather than relying on generic supplier specifications.
Q6: What should I verify before purchasing?
Confirm the order number, module designation, revision, connectors, mounting arrangement, and compatibility with the installed and converter hardware. For used or refurbished stock, request condition disclosure and documented test results.
Q7: What testing is appropriate before commissioning?
Testing should follow the applicable ABB procedure and the site’s excitation-system commissioning plan. Depending on the approved procedure, this may include hardware inspection, interface checks, diagnostics, and verification of converter-control operation by qualified personnel.
Procurement Recommendation
For the ABB 3BHE025541R0101, prioritize exact part-number matching and confirmation of the -CCI application. Do not approve a substitute based only on similar dimensions or a generic “controller module” description. Request clear identification photographs, revision details, and test documentation, and verify the required electrical and interface specifications against the applicable ABB manual before installation.
