Product Description
GE MULTILIN UR9EV is the CPU Processor & CT/VT Acquisition Module of Multilin UR Universal Relay series, the main core board unit for UR protection relays. It integrates three-phase current and voltage transformer signal acquisition and protection algorithm calculation. The module collects CT/PT analog signals, executes relay protection logic, fault disturbance recording and sequence of events (SOE). Equipped with Ethernet port, it supports protection setting configuration, data uploading and GOOSE message communication. Adopted pluggable modular design, it is installed inside UR relay chassis, providing core computing and electrical quantity acquisition for the whole power protection device. It complies with ANSI and IEC power standards and widely used in substation relay protection retrofit.

Product Application
As the core processing module for UR universal protection relays, it is applied in power substation and power plant switchgear protection equipment. It supports protection relays for transmission lines, transformers, generators and capacitor banks. It samples current & voltage signals, runs protection logic, executes fault judgement, trip logic and disturbance waveform recording. Combined with UR chassis and I/O modules, it connects to SCADA and DCS systems to upload telemetry, remote status, alarms and fault waveforms. Widely used in power grid, captive power plants and industrial power distribution relay protection systems.
