The GE Multilin UR9EH is a high‑performance CPU module that serves as the central processing core for the Universal Relay (UR) series. As the “brain” of the relay, the GE Multilin UR9EH executes all protection algorithms, control logic, and communication tasks, processing real‑time data from CT/VT modules to detect faults and issue trip commands within milliseconds. The GE Multilin UR9EH supports multiple communication protocols including IEC 61850, DNP3, and Modbus, enabling seamless integration with SCADA, DCS, and other automation systems. With hot‑swap capability, advanced self‑diagnostics, and field‑upgradable firmware, the GE Multilin UR9EH delivers reliable, flexible performance for critical power system protection and control applications.
Power generation – generator protection, transformer protection, switchgear monitoring
Transmission & distribution – substation equipment, power line protection, capacitor bank protection
Industrial power systems – motor protection, reactor protection, UPS systems
Renewable energy – wind turbines, solar inverters, battery energy storage protection
Petrochemical – refinery process equipment, compressors, pipeline pump monitoring
Metallurgy – electric arc furnaces, rolling mills, motor protection
High‑speed processing – executes instructions in as little as 10 μs for fast fault detection and trip response
Multi‑protocol communication – supports IEC 61850, DNP3, Modbus TCP/RTU, and IEC 60870‑5‑104
FlexLogic™ programmable logic – user‑definable control and automation logic for custom protection schemes
Hot‑swappable design – supports online replacement without system shutdown or interruption
Comprehensive protection functions – overcurrent, differential, voltage, frequency, thermal, and reverse power protection
Advanced fault recording – 1000+ fault records and waveforms for post‑fault analysis
Self‑diagnostics – built‑in hardware and software fault detection with LED status indicators
Field‑upgradable firmware – update via EnerVista UR software over Ethernet or serial connection
Plug‑&‑play auto‑configuration – automatically establishes basic settings, reducing setup time
Dual Ethernet ports – independent 10/100Base-TX ports for purpose‑specific LAN segregation
Executes protection algorithms – runs overcurrent, differential, voltage, frequency, and thermal protection logic
Processes real‑time field data – ingests digitized analog data from CT/VT modules and status contacts from digital I/O
Performs FlexLogic™ control – executes user‑defined logic for interlocking, sequencing, and custom trip schemes
Manages system communication – exchanges data with SCADA, DCS, and other devices via Ethernet, serial, and fieldbus protocols
Records fault and event data – captures high‑resolution oscillography and sequence of events (SOE) data for post‑event analysis
Coordinates with I/O modules – communicates with CT/VT, digital I/O, and transducer modules via the high‑speed internal UR bus
Performs self‑diagnostics – continuously monitors hardware and software health, reporting faults via LEDs and SCADA
