Brand: ABB
Series / Family: UF C9xx / C911 interface / control module family
Model / Part Number: UF C911 B106 — 3BHE037864R0106
Type: Interface / controller board / internal module
Role: Board used inside drive / automation systems to provide communication, control, and interfacing between subsystems
The UF C911 B106 (3BHE037864R0106) is a compact internal interface/control module intended for integration within ABB drive / automation enclosures. This module handles internal logic, protocol bridging, diagnostics, and signal interface tasks. It is varnished or coated to resist contamination, and designed to mount into fixed connectors or slots inside the drive cabinet.
It typically works alongside other modules and boards to deliver a fully integrated drive / control system, connecting field signals (analog, digital, sensors) with the drive logic and higher level controllers (PLC, SCADA systems).
Typical use cases include:
Embedded in ABB drives as the communication / interface board
Bridging signals between PLC / fieldbus networks and internal drive logic
Processing sensor inputs (temperature, current, voltage) and feeding them to the drive controller
Monitoring internal parameters, faults, and diagnostics
Use in industrial systems: pumps, fans, conveyors, compressors, process control
Replacement / upgrade board in existing ABB drive/automation panels
Key advantages of this module include:
Native compatibility — Designed specifically for ABB’s UF C9xx series environment
Robust construction — Protective varnish, shielding for harsh industrial conditions
Compact and lightweight — Fits inside tight spaces without bulk
Integrated diagnostics — Monitors health, signals, and fault conditions internally
Protocol flexibility — Supports multiple communication standards to interface with external systems
Low power draw — Efficient logic circuits reduce internal heat
Modular design — Easy to replace or upgrade without large changes
Reliable performance over temperature — Works stably across industrial ranges
Good spare availability — Recognized part for replacement in ABB systems
Longevity and maintainability — Supports long service life in field installations
