Product Details
The UFC762AE101 3BHE006412R0101 is control signal processing board for ABB UNITROL 5000 generator excitation system.
This UFC762AE101 board undertakes important signal transmission and processing work inside excitation cabinet. It adopts optical fiber communication to improve anti‑interference ability in complex power‑plant electromagnetic environment.
It receives control commands from main control board, forwards trigger signals to power unit interface board, and collects operating status and fault feedback from power unit in real time.
High‑speed bus ensures low‑delay data exchange, guarantees synchronous execution of excitation regulation, thyristor triggering and protection logic.
On‑board hardware monitoring circuit can detect communication abnormality, signal loss and channel failure, and output corresponding alarm signals.
Conformal coated circuit board adapts to harsh industrial environment, improves moisture‑proof and anti‑dust performance.
Standard plug‑in structure supports convenient on‑site maintenance and replacement.
It is widely used in generator excitation system overhaul and renovation projects of thermal power plants and hydropower stations.
It is important spare hardware for excitation cabinet maintenance, signal loop debugging and defective UFC762AE101 board replacement.
