Important specification note: Public references for UFC718AE01 are unusually inconsistent. One source identifies it specifically as a main circuit interface board and lists 24 VDC input, 0–10 VDC output, and Modbus RTU, while other listings describe it as a frequency/count module or a broader control board.
I would not use the published 0–10 V, Modbus, temperature, or dimensional figures as final engineering specifications without checking the ABB documentation for the installed system. The UFC718AE01 / HIEE300936R0101 identity is much better supported than the detailed secondary specifications.
Application Scenarios & Pain Points
Power-electronics interface boards are rarely replaced during routine maintenance. They tend to become suspects after a converter develops gate-control, feedback, synchronization, or main-circuit communication problems. That makes troubleshooting discipline important.
- ABB power-conversion equipment: The UFC718AE01 is identified as a main circuit interface board used to connect control electronics with power-conversion hardware.
- AC 800PEC-related systems: Some technical references associate this board with ABB AC 800PEC power-electronics control architecture.
- UNITROL 6000 applications: The same reference family associates UFC718AE01 with UNITROL 6000 excitation equipment.
- Legacy drive maintenance: A tested spare can be valuable when the original converter is still operationally necessary but the board is no longer readily supported.
Field note: Before replacing the board, inspect the mating connectors and adjacent power electronics. If there is carbon tracking, heat discoloration, or damaged semiconductor hardware nearby, installing another interface board without finding the original fault can turn one failed board into two.

The Engineer’s Guide: Field Pitfalls to Avoid
WARNING 1 — Do not trust a generic description of .
The available market references disagree significantly. One calls it a main circuit interface board, another describes frequency/count functionality, while others provide broad control-module descriptions.
How to avoid it: Match the physical board label, HIEE300936R0101, PCB revision, rack/slot position, and the ABB equipment model in which the board is installed.
WARNING 2 — Do not replace the board before checking the power stage.
A damaged IGCT, gate-driver circuit, snubber, current transformer interface, or DC-link fault can damage a replacement interface board.
How to avoid it: Inspect adjacent power components for burn marks, cracked components, abnormal resistance, loose bus connections, and evidence of overtemperature before energizing the replacement.
WARNING 3 — Verify connector orientation and backplane seating.
This type of board carries control and interface signals that can be sensitive to connector alignment and ESD.
How to avoid it: Isolate all relevant power sources, use an ESD-controlled work area, inspect connector pins under good lighting, and seat the board evenly. Never force a board into a backplane—especially when the connector is partially misaligned.
Frequently Asked Questions (FAQ)
What is ABB HIEE300936R0101?
It is an ABB main circuit interface board identified by model and ordering number HIEE300936R0101. Available technical references associate it with ABB power-electronics equipment and describe its role as an interface between control electronics and the main circuit.
Is a PLC or DCS I/O module?
No—not in the conventional sense. It should primarily be treated as power-electronics interface hardware.
Some secondary databases classify it as a generic control module, frequency/count module, or communication device. Those descriptions should not override the more specific identification of as a main circuit interface board.
Which ABB systems use ?
Available references associate the board with ABB AC 800PEC power-electronics control systems and UNITROL 6000 excitation equipment.
Because the public documentation is inconsistent, the installed equipment model should be verified before procurement. The same part number should not be assumed suitable across every ABB power-electronics application.
What is the power supply for ?
Several available listings specify 24 VDC, but detailed electrical information is not consistently documented across sources.
For a replacement, use the installed system documentation and board markings as the authority. Do not energize an unknown board based solely on a third-party listing.
Can be replaced by another UFC-series board?
Not without an engineering compatibility check.
Compare:
- Complete model number
- HIEE ordering number
- PCB/hardware revision
- Installed ABB system
- Rack or mounting position
- Connector arrangement
- Power supply
- Feedback/interface signals
- Firmware or configuration dependencies
The UFC family contains multiple specialized boards. Similar numbering does not mean functional equivalence.
How should a refurbished be tested?
For a critical converter spare, I would request:
- Verification of / .
- Photograph of the actual PCB and nameplate.
- Hardware revision identification.
- Visual inspection for burned components and PCB contamination.
- Connector and backplane inspection.
- Controlled power-up.
- Interface-signal verification.
- Communication/interface testing where applicable.
- Extended operating test.
- Documented test results.
A simple continuity test is not sufficient. If this board sits between the control system and a high-power converter, the test should demonstrate actual interface behavior under controlled conditions.
What should I ask a supplier before purchasing ?
Request the exact part-number photograph, PCB revision, equipment/application from which the board was removed, condition, test report, and warranty terms.
For a shutdown-critical spare, I would also ask whether the board has been electrically tested rather than merely inspected. With legacy ABB power-electronics hardware, that distinction can save a considerable amount of troubleshooting time after installation.
