Description
The ABB UFC911B108 3BHE037864R0108 is identified in current spare-parts references as a UF C911 B108 control/current-measurement board. One technical listing specifically identifies it as a CVMI2 current measurement board for ABB ACS580MV medium-voltage drives, while other listings describe the same part number more generally as a main control board.
For an industrial replacement listing, the safest description is therefore CVMI2 / UF C911 B108 control and current-measurement board, rather than calling it a generic PLC module. The exact application should be confirmed from the installed drive configuration and board nameplate.

⚡ Functional Description
The board is used within ABB medium-voltage drive equipment for current measurement and associated control functions. Current feedback is essential for monitoring motor operation and supporting the drive’s control and protection functions.
The part number 3BHE037864R0108 is consistently associated with UF C911 B108, although online sellers use different descriptions such as control board, processor module, power module, and current-measurement board.
For sales documentation, I recommend using “CVMI2 Current Measurement / Control Board” and avoiding unsupported claims about specific I/O counts or communication protocols.
🏭 Typical Applications
- ABB ACS580MV medium-voltage drives
- Medium-voltage motor control
- Industrial motor drives
- Mining and minerals processing
- Cement plants
- Pumps and fans
- Compressors

🛠️ Commissioning Checklist
- Confirm board identification
- Inspect connectors and PCB condition
- Verify drive auxiliary power
- Check current measurement feedback
- Check drive diagnostic status
- Verify communication with the control system
- Confirm parameter/configuration compatibility
- Perform low-load motor testing
- Check current balance and feedback values
- Review alarms before full-load operation
⚠️ Replacement Note
There is a significant amount of conflicting information in secondary listings for this part. For example, one source calls UFC911B108 a main control board, another calls it a processor module, while a more specific parts listing identifies 3BHE037864R0108 as “CVMI2” for an ACS580MV VFD.
Therefore, for a professional product listing, it is better to state the verified part number and CVMI2/ACS580MV association and avoid inventing detailed electrical specifications.
