GE UR8GH Universal Relay Rear Communication Module – UR Series

GE UR8GH Universal Relay Rear Communication Module – UR Series

When a substation protection relay loses its communication backbone, the consequences cascade instantly: SCADA visibility goes dark, event logs stop recording, and engineering teams are left blind during the most critical moments of grid disturbance. The GE UR8GH Rear Communication Module is the precision interface that prevents this scenario — a purpose-engineered slot module that maintains the data link between the UR Series relay and your control network, ensuring uninterrupted protection coordination and real-time telemetry.

Within GE’s UR Series platform — one of the most widely deployed digital protection relay families in global power utility and industrial automation — the UR8GH occupies the rear slot 8 position, providing dedicated communication port expansion. Its adoption spans transmission utilities, industrial switchgear OEMs, and large-scale renewable energy installations across North America, Europe, and Asia-Pacific, making it one of the most sought-after replacement and spare modules in the protection relay aftermarket.

Key Features & Benefits

• Hot-swap compatible with UR Series chassis — minimizes maintenance downtime in live substations
• Multi-protocol support enables seamless integration into legacy SCADA and modern IEC 61850 architectures
• Rear-slot design keeps front panel access unobstructed for local HMI operation during communication maintenance
• Industrial-grade construction rated for harsh substation environments including wide temperature range and high EMI immunity
• Direct OEM replacement — maintains relay type-test certification without re-commissioning the entire IED
• Fiber optic port option provides galvanic isolation for long-distance or high-noise communication runs

Industry & Equipment Applications

• Power Transmission & Distribution: Substation automation, line protection IED communication, SCADA integration
• Renewable Energy: Wind farm and solar plant protection relay communication networks
• Industrial Plants: Motor protection relay communication in petrochemical, mining, and cement facilities
• Railway Electrification: Traction substation protection relay systems
• Data Centers & Critical Infrastructure: UPS and switchgear protection relay monitoring

System Integration & Compatible Parts

The UR8GH is designed for use within GE’s UR Series relay platform. Compatible host relays and related modules include:

• GE UR Series relays: C60, C70, D60, F35, F60, G60, L60, L90, M60, N60, T35, T60
• UR chassis rear slot modules: UR6xx, UR7xx, UR8xx series slot cards
• GE EnerVista UR Setup software for configuration and firmware management
• Compatible with GE MiCOM S1 Agile and third-party IEC 61850 engineering tools

When sourcing replacement modules, always cross-reference the full relay order code (found on the relay nameplate) to confirm slot position and port type compatibility.
