ABB’s product records identify 3BHE033067R0101 as GC C960 C101 and describe it as a PC board, while ABB-related catalog records identify the same part number specifically as a phase interface board and note that the PCB is varnished.
I would not assign a standalone 24 VDC supply, RS-485/RS-422 ports, PWM output rating, or specific environmental rating to this board from the available evidence. Several reseller pages describe it as an “inverter main control board” or “digital output controller,” but those descriptions conflict with the more specific phase-interface-board classification found in ABB-oriented catalog data.
Product Introduction
The ABB GC C101 3BHE033067R0101 is a varnished phase interface PCB associated with ABB power-conversion equipment. Available catalog records place it within the GC hardware family and identify the board specifically as a phase interface board. It is also listed in component records associated with ABB ACS2000 and PCS6000 equipment, so its role should be understood in the context of the complete converter architecture rather than as a generic PLC I/O card.
The distinction between a phase interface board and a main control processor is important during maintenance. Some aftermarket descriptions call GC C101 an inverter motherboard or main control board, but that terminology is not consistent across available records. For procurement and engineering work, the exact ABB type designation and product ID should take precedence over generic reseller descriptions.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
The primary risk with is ordering based only on the phrase “GC ” without confirming the exact board variant. ABB records separately identify , , and . The C103 version is also identified as a varnished phase interface board, which shows that the suffix is not cosmetic.
Typical Applications
- Phase-interface circuitry within ABB medium-voltage power-conversion equipment.
- Maintenance of existing ABB ACS2000 converter installations where this board is part of the installed hardware set.
- PCS6000-related converter maintenance and control-cabinet refurbishment.
- Replacement of an installed GC C101 board after component-level failure, provided the converter configuration is confirmed.
Technical Pitfalls to Avoid
- Do not classify it as a conventional digital output module. One reseller does so, but other records identify the part as a phase interface board. The electrical function must be verified from the installed converter drawings.
- Do not assume and C102 are interchangeable. ABB-oriented catalog records list them as separate phase-interface-board variants: corresponds to 3BHE033067R0101, while C102 corresponds to 3BHE033067R0102.
- Check the complete converter configuration. A PCB with the correct basic identifier can still be unsuitable if the converter generation, cabinet position, firmware environment, or connected phase-interface hardware differs.
- Verify the physical board marking. Compare the ABB product ID, GC designation, revision marking, connector layout, and PCB artwork against the failed board before installation.
- Do not transfer specifications from another GC board. The family contains different functional boards, and public reseller descriptions sometimes mix their functions. Use the exact ABB part number and cabinet documentation when confirming electrical interfaces.
- Inspect the surrounding power-converter hardware. If the original board failed after a power-stage fault, check the associated gate-drive units, phase electronics, feedback circuits, cooling system, and power semiconductor assemblies before commissioning the replacement.

Procurement and Replacement Note
For a replacement , specify ABB GC / 3BHE033067R0101 exactly. Before approving the replacement, compare the original board’s PCB marking, revision, varnished/coated finish, connector arrangement, cabinet position, converter model, and associated phase/gate-drive hardware.
The available evidence supports identifying this unit as a GC phase interface board, but does not reliably establish a standalone electrical specification sheet for the exact board. I would therefore avoid publishing guessed voltage, current, communication, or temperature values as fixed specifications. For a live converter replacement, the installed ABB electrical drawings and board artwork should control the final compatibility decision.
