GE UR 7KH Communications Module – UR Series

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.

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.

System Integration & Compatible Parts

Every GE UR 7KH unit processed by DriveKNMS passes through a structured 5-step quality verification protocol:

1. Visual Inspection — Physical damage assessment, corrosion check, connector integrity verification, and authenticity label validation.
2. Power-On Functional Test — Unit is energized and communications port behavior, LED status indicators, and protocol handshake responses are verified.
3. Part Number & Revision Verification — Firmware version, hardware revision, and part number are cross-referenced against manufacturer records to confirm exact specification match.
4. ESD-Safe Packaging — Modules are packed in anti-static bags with foam cushioning and moisture barrier materials, rated for international air freight handling.
5. RFQ terms review: Commercial terms are confirmed during RFQ review based on model, condition, documentation, quantity and destination.

Global Logistics: We ship worldwide via FedEx, DHL, and UPS Express services. routing documentation when applicables are provided upon dispatch. Typical transit times: 3–7 business days to most destinations.
