Product Overview
The GE UR9KH is a high-performance CPU module designed for GE Multilin’s UR Series Universal Relays, delivering advanced processing power and communication capabilities for critical power system protection and automation. As part of General Electric’s (GE) industrial automation portfolio, the GE UR9KH serves as the core computing engine for UR series relays, enabling real-time monitoring, protection, and control in applications such as power generation, transmission, and distribution. This module supports dual communication ports (10/100Base-T Ethernet and RS485) and is certified for SIL 2 safety applications under IEC 61508, making it ideal for environments requiring high reliability and fault tolerance.
The GE UR9KH features a 32-bit RISC processor and 256 MB of memory, providing fast execution of complex protection algorithms and logic control. Its Modbus RTU/TCP and IEC 61850 communication protocols enable seamless integration with SCADA systems, PLCs, and smart grid infrastructure, facilitating remote configuration, data logging, and predictive maintenance. The module supports hot-swappable functionality, allowing maintenance without system downtime, even in hazardous areas (Class 1, Div 2/Zone 2). With wide operating temperature range (-40°C to +70°C) and IP20-rated enclosure, the GE UR9KH ensures reliable performance in harsh industrial environments, including oil refineries, power plants, and mining operations.
The GE UR9KH supports IEC 61850 process bus technology, enabling digital substation automation with reduced wiring complexity and enhanced interoperability. Its programmable logic controller (PLC) functionality allows custom control sequences, such as interlocking, permissive logic, and alarm management, while the integrated event recorder captures up to 8,000 events with timestamping for detailed fault analysis. This module is compatible with GE’s EnerVista UR Setup software, providing a user-friendly interface for configuration, firmware updates, and diagnostic tools.
