Product Introduction
ABB UFC911B106 3BHE037864R0106 Overview
The ABB UFC911B106 3BHE037864R0106 is a CVMI2B voltage measurement and interface board used in ABB medium voltage drive systems. It handles voltage feedback signals required by the drive control architecture and supports accurate monitoring inside systems such as ACS6000 platforms.
This module is mainly relevant during drive maintenance, fault recovery, and legacy system support. A replacement board must match the installed drive type, hardware revision, and application parameters. A similar-looking ABB board is not automatically interchangeable.

Application Scenarios & Field Pitfalls (The Engineer’s Perspective)
Engineering Pain Point
A medium voltage drive fault often appears simple from the operator panel: an overvoltage alarm, missing feedback signal, or converter trip. The actual cause can be a failed measurement board, damaged interface connection, incorrect replacement revision, or a problem upstream in the power section.
For the UFC911B106, replacing the board is only one part of the repair process. The feedback chain must be verified before returning the drive to production.
Typical Applications
- Power Generation — Medium voltage motor drives for pumps, fans, and auxiliary equipment
- Oil & Gas Facilities — Variable speed control for compressors and process pumps
- Mining Operations — High-power conveyor and mill drive systems
- Water Treatment Plants — Large pump motor speed regulation
Technical Pitfalls to Avoid
- Confirm the exact ABB material number
UFC911B106 and 3BHE037864R0106 must match the installed board identification. ABB drive systems often contain similar interface boards with different electrical functions.
- Do not replace without checking drive parameters
Measurement scaling, protection settings, and control calibration may depend on the installed drive configuration. A board replacement may require verification before startup.
- Inspect connectors and signal wiring
Many drive faults blamed on a measurement board are caused by loose connectors, contamination, or damaged signal cables. Check the complete measurement path.
- Follow medium voltage safety procedures
This module belongs to a high-energy drive environment. Confirm discharge status and isolation procedures before accessing the cabinet.

Procurement Note:
The ABB / 3BHE037864R0106 is a specialized drive interface board. Before purchasing, confirm the installed drive model, board revision, application type, and failure symptoms. For medium voltage systems, the correct spare is determined by the complete drive configuration, not only the board part number.
