Product Details

The UFC718AE101 HIEE300936R0101 HIEE410516P201 is universal control interface board for ABB UNITROL 5000 generator excitation system。

This UFC718AE101 board serves as intermediate signal link between main control processor and thyristor power unit.

It receives control pulses from main board, processes and distributes trigger signals for thyristor power components.

It collects real‑time working feedback signals from power unit and transmits status information back to main control board.

Built‑in hardware monitoring circuit can detect trigger abnormality, phase unbalance and signal loss, output corresponding fault alarm information.

Adopts optocoupler isolation design to enhance anti‑interference capability for complex power plant electromagnetic environment.

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, trigger loop debugging and defective UFC718AE101 board replacement.
