Product Details

ABB UFC760BE41 3BHE004573R0041 is an INU interface board for ABB UNITROL generator excitation control systems. The INU interface board serves as 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 UFC760BE41 board samples generator analog and digital signals, and transmits processed data to the main exciter controller for closed-loop excitation regulation algorithm calculation. The exciter control interface board adopts isolation circuit design to block electromagnetic interference from power circuits and guarantee stable signal transmission in power plant environments. It has built-in self-diagnostic function to continuously monitor signal connection status, detect wire breakage or signal loss and output fault alarm messages. It can cooperate with other excitation modules 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 simple installation and quick field replacement.
