Product Details

The UCD240A101 3BHE022287R0101 (CCM6080) is the core main control board of ABB UNITROL 6000 generator excitation system.

This board is the central computing unit of the excitation regulator. It executes AVR automatic voltage regulation, manual field current control, power system stabilizer PSS, over‑excitation / under‑excitation limitation and multiple protection logics. It exchanges data with signal acquisition boards and pulse trigger boards via backplane and optical links, completes overall logic calculation of the excitation system, and outputs control commands to drive subsequent pulse‑generating units.

Front‑panel LED indicators show module power‑on, running, communication and fault status for quick on‑site inspection. Built‑in rich self‑diagnosis functions, it can record fault events and upload alarm information to upper monitoring system. Conformal coated circuit board enhances moisture‑proof and anti‑interference capability, adapting to harsh electromagnetic environment in power plant workshops.

It belongs to key spare‑part for generator excitation equipment maintenance, widely used in overhaul and renovation projects of thermal power, hydropower and pumped‑storage generating units.

It is important spare hardware for excitation regulator loop debugging and defective UCD240A101 board replacement.
