Product Details

The UFC911B110 3BHE037864R0110 is analog input and output signal board for ABB UNITROL 5000 generator excitation system.

This UFC911B110 board undertakes all kinds of field signal acquisition and output work inside the excitation cabinet.

It samples generator terminal voltage, excitation current and other analog signals, converts them into digital data for main processor calculation.

It supports analog output for external indication and multiple binary input and relay output channels for interlock and protection logic.

Each signal channel adopts galvanic isolation design, which effectively suppresses interference from power circuit and improves system stability.

It communicates with main control board through internal bus, completes real‑time transmission of measurement data and control commands.

Built‑in hardware self‑diagnosis function can detect channel abnormality and signal fault and trigger alarm output.

Plug‑in structure facilitates on‑site maintenance and board replacement.

Widely applied in generator excitation renovation and maintenance projects for thermal power plants and hydropower stations.

It is important spare hardware for excitation system overhaul, signal loop debugging and defective UFC911B110 board replacement.
