GE UR-9CH Universal Relay Central Processor Module

Description

TheUR-9CHis ahigh-performance CPU processor moduledeveloped byGE Multilinfor theUniversal Relay (UR) series. Serving as thecentral processing unitwithin theUR chassis, it executesprotection algorithms,control logic, andsystem diagnostics. The module plays a crucial role in coordinating the operation of other UR modules, such asCT/VT inputs,transducer I/O, andcommunication interfaces. Designed forsubstation-grade reliability, the UR-9CH supportsreal-time fault detection,event recording, andsystem configuration, making it an essential component inGE’s protection and control architecturefor power systems.
