Product Details And Specifications

GE UR 7KH Communications Module – UR Series

In mission-critical environments such as oil & gas facilities, power generation plants, and petrochemical complexes, the integrity of protection relay communications is non-negotiable. The GE UR 7KH Communications Module serves as the backbone of inter-device data exchange within GE's Universal Relay (UR) platform, enabling real-time status reporting, SCADA integration, and peer-to-peer relay coordination. A single communications failure in these environments can cascade into unplanned downtime events costing operators tens of thousands of dollars per hour — making the UR 7KH a critical spare that no facility can afford to overlook.

Within the GE UR Series architecture, the UR 7KH occupies a specialized role as a high-density communications interface module, supporting multiple industrial protocols and physical media types. Since its introduction as part of GE Grid Solutions' Universal Relay platform, the UR Series has been deployed across substations, generating stations, and industrial plants on every continent, establishing itself as one of the most trusted protection and control relay families in the global power industry.

Key Features & Benefits

• Multi-Protocol Communications Support — Supports IEC 61850, DNP3, Modbus, and GOOSE messaging, enabling seamless integration into modern SCADA and DCS architectures without gateway hardware.
• Modular Hot-Swap Design — Engineered for insertion and removal within the UR chassis without powering down the relay, dramatically reducing planned maintenance windows and eliminating unnecessary process interruptions.
• High-Speed Data Throughput — Delivers low-latency signal exchange between protection relays and control systems, meeting the stringent timing requirements of real-time protection coordination loops.
• IEC 61850 GOOSE Messaging — Enables peer-to-peer relay tripping and interlocking over Ethernet, replacing hardwired logic with flexible, software-configurable protection schemes.
• Industrial-Grade Durability — Designed to withstand substation-class electromagnetic interference (EMI), vibration, and wide temperature cycling in accordance with IEC 60255 and IEEE C37.90 standards.
• Pre-Shipment Functional Verification — Every unit undergoes 100% power-on functional testing and protocol response verification before dispatch, ensuring plug-and-play readiness upon arrival.
• Fiber Optic Isolation — Optical communication ports provide galvanic isolation between relay and network infrastructure, protecting sensitive electronics from ground potential rise (GPR) events.

Industrial Applications

• DCS Distributed Control Systems — Integrates UR Series protection relays into plant-wide DCS networks via standardized industrial protocols, enabling centralized monitoring and event logging for process control infrastructure.
• ESD Emergency Shutdown Systems — Provides the communications link between protection relays and safety PLCs in safety instrumented systems (SIS), supporting IEC 61511-compliant safety interlock architectures.
• Substation Automation (SA) — Core component in IEC 61850-based substation automation projects, enabling bay-level protection, control, and monitoring integration with station-level HMI and SCADA systems.
• Turbine & Generator Protection — Supports communications between generator protection relays and turbine control systems in gas turbine, steam turbine, and hydro generator applications.
• Offshore Platforms & FPSO — Qualified for harsh marine environments where reliable relay communications are essential for electrical protection of offshore power distribution systems.
• Nuclear Plant Instrumentation & Control — Applicable in non-safety-class I&C systems where IEC 61850 communications are required for monitoring and event reporting, subject to site-specific qualification requirements.
