Product Details

ABB UFC760BE1142 3BHE004573R1142 is an INU interface board for ABB UNITROL generator excitation control systems. The INU interface board realizes high-speed signal exchange between the exciter controller and on-site I/O units, responsible for signal conditioning, electrical isolation and transmission of excitation feedback signals. This ABB UFC760BE1142 board converts analog and digital signals from generator voltage and current sampling, and transmits processed data to the main exciter control unit for closed-loop excitation regulation. The exciter control interface board adopts reliable isolation circuit design to block electromagnetic interference from power circuits and guarantee stable signal transmission in power plant environments. It has built-in continuous hardware self-diagnostic function to detect wire faults, signal loss and circuit abnormalities, and send fault alarm information to the main controller. It can cooperate with other excitation modules to execute overexcitation, underexcitation and other 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.
