Product Details

ABB UFC760BE42 3BHE004573R0042 is an INU interface board developed 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, responsible for signal conditioning, electrical isolation and transmission of excitation feedback signals. This ABB UFC760BE42 board collects analog and digital signals of generator voltage and current, converts and transmits the processed data to the main exciter controller to realize fast closed-loop excitation regulation. The exciter control interface board adopts reliable isolation circuit design to suppress electromagnetic interference from power cabinets and guarantee stable signal transmission. It is equipped with built-in self-diagnostic function to continuously monitor hardware working status and output fault alarm information in case of abnormal signal or circuit failure. It cooperates with the main control module to execute protection actions such as overexcitation, underexcitation and loss-of-field protection for generator units. Widely applied in thermal power and hydropower generator UNITROL excitation cabinets, it is essential spare part for system maintenance and renovation. It adopts rack plug-in structure for simple installation and quick field replacement.
