ABB UNS0863A-PV1 HIEE305082R1 UNITROL F Excitation System Digital I/O Interface Board

Product Description

ABB UNS0863A-PV1 (Part No. HIEE305082R1) is a digital I/O interface card for UNITROL F excitation system, a plug-in Eurocard module. It serves as the signal acquisition and output component for UNITROL excitation controllers. Equipped with multi-channel digital inputs and outputs with opto-galvanic isolation, it handles logic signal acquisition, relay command output, status feedback and fault signal exchange for excitation systems. Channel LED indicators are provided. It communicates with UNITROL5000/6000 excitation main controller via backplane bus. Featuring high reliability and strong anti-interference capability, it is used for discrete interlock and protection signal exchange of generator excitation systems. Manufactured in Switzerland, it is critical spare part for power plant excitation cabinets.
