GE UR7IH UR-7IH Communication Module – Multi-Protocol Industrial Gateway | Universal Relay Platform
Engineering Background
The GE UR7IH is a plug-in communication module designed exclusively for GE’s Universal Relay (UR) series protection and control platform — one of the most widely deployed digital relay architectures in transmission substations, generation facilities, and industrial power systems worldwide. The UR platform’s modular slot architecture allows engineers to configure relay functionality precisely to system requirements, and the UR7IH fills the critical role of substation communication gateway, enabling seamless integration between field protection devices and SCADA/DCS control layers.
Product Positioning
The UR7IH is engineered for protection engineers and substation automation specialists who require deterministic, high-reliability communication between GE UR-series relays and supervisory control systems. It supports multiple industrial protocols simultaneously, making it the preferred choice for brownfield upgrades and greenfield IEC 61850-compliant substation designs.

Proven Application Environments
- Transmission Substation Automation — IEC 61850 GOOSE messaging for inter-relay tripping and interlocking across bay-level and station-level networks
- Generation Plant Protection — DNP3 communication to plant DCS for generator protection relay status monitoring and control
- Industrial Power Distribution — Modbus TCP/RTU integration with plant SCADA for motor protection and feeder management relays
- Brownfield Substation Upgrades — Retrofit into existing UR chassis to add modern protocol support without replacing the entire relay
- Smart Grid & Digital Substation Projects — IEC 61850 Ed.2 compliant deployments requiring GOOSE, Sampled Values, and MMS reporting
Engineering Advantages
- Multi-Protocol Simultaneous Operation — Run IEC 61850, DNP3, and Modbus concurrently on a single module, eliminating the need for external protocol converters
- Hot-Swap Capable — Designed for insertion and removal from the UR chassis without full system shutdown (subject to site safety procedures)
- Deterministic Latency — GOOSE messaging latency <4 ms, meeting IEC 61850 Performance Class P2/P3 requirements for protection applications
- Cybersecurity Ready — Supports role-based access control (RBAC) and encrypted communications aligned with NERC CIP requirements
- Wide Temperature Range — Rated for -40°C to +85°C, suitable for outdoor substation control houses and harsh industrial environments
- GE EnerVista Software Integration — Full configuration and diagnostics via GE’s EnerVista UR Setup software suite
System Architecture & Signal Flow
The UR7IH occupies the H-slot (communication slot) within the UR series modular chassis. Internally, it interfaces with the UR CPU module via the chassis backplane, accessing real-time protection data, event records, and control outputs. Externally, the module presents dual Ethernet ports (or fiber + copper depending on sub-variant) for station bus (IEC 61850) and process bus connectivity, plus an RS-485 serial port for legacy DNP3/Modbus RTU devices.
Typical Signal Flow: Field CT/VT inputs → UR CPU (protection processing) → UR7IH backplane interface → Ethernet/Serial output → SCADA/DCS/HMI

Technical FAQ
Q: Is the UR7IH compatible with all UR series relay models?
A: The UR7IH is designed for the H-slot (communication slot) of UR series chassis. Compatibility depends on the specific UR relay model and firmware version. Please confirm your relay model (e.g., C60, D60, L90, T60) and firmware version before ordering.
Q: Can the UR7IH support IEC 61850 Ed.2 and DNP3 simultaneously?
A: Yes. The UR7IH supports simultaneous multi-protocol operation. IEC 61850 (GOOSE/MMS) and DNP3 can run concurrently on separate network interfaces.
Q: What GE EnerVista software version is required for UR7IH configuration?
A: EnerVista UR Setup v7.xx or later is recommended. Contact Konmask technical support for software compatibility guidance specific to your firmware version.
Q: Do you provide a warranty on surplus UR7IH modules?
A: Yes. Konmask.com provides a 90-day functional warranty on all surplus modules. New/unused stock carries the original GE warranty terms where applicable.
Q: Can you supply multiple units for a substation project?
A: Yes. We maintain stock and can source project quantities. Contact us with your BOM for a consolidated project quotation.
