Product Details

The UFC718AE101 HIEE300936R0101 is main circuit interface trigger board for ABB UNITROL 5000 generator excitation system.

This UFC718AE101 board serves as critical signal link between main control processor and thyristor power unit. It receives trigger instructions from main control board and distributes precise gate pulses to thyristor components.

It collects real‑time operating status and fault feedback from power unit, and transmits feedback information back to main controller for protection logic judgment.

Adopts optocoupler isolation and fiber‑optic transmission design, effectively resisting strong electromagnetic interference in power plant environment.

On‑board monitoring circuit can detect pulse loss, phase abnormality and channel failure, and output corresponding fault alarm signals.

Conformal coated circuit board improves moisture‑proof and anti‑dust performance for harsh industrial site.

Standard plug‑in structure supports fast on‑site replacement without complex wiring modification.

It is widely used in overhaul and renovation projects of thermal power plants and hydropower station generator excitation systems.

It is important spare hardware for excitation cabinet maintenance, trigger loop debugging and defective UFC718AE101 board replacement.
