Product Details

ABB UFC760BE43 3BHE004573R0043 is an INU interface board for ABB UNITROL generator excitation control systems. The INU interface board serves as the signal bridge between the exciter controller and field I/O units, completing signal conditioning, electrical isolation and transmission of excitation feedback signals. This ABB UFC760BE43 board collects analog and digital signals of generator voltage and current, converts and transmits processed data to the main exciter controller to realize closed-loop excitation regulation. The exciter control interface board adopts reliable isolation circuit design to suppress electromagnetic interference inside power cabinets and guarantee stable signal transmission. It has built-in self-diagnostic function to continuously monitor signal connection status, detect wire breakage and circuit abnormalities, and output fault alarm information. It cooperates with the main control module to execute overexcitation, underexcitation and loss-of-field protection actions for generator units. Widely used in thermal power and hydropower UNITROL excitation cabinets, it is essential spare part for excitation system maintenance and renovation. It adopts rack plug-in structure for convenient installation and quick field replacement.
