GE Multilin UR-7JH UR 7JH Relay Communications Module

GE Universal Relay (UR) Family
High-Performance Protection, Control, and Automation

The Universal Relay (UR) family from GE provides a unified, modular platform for protection, control, monitoring, and automation of critical electrical assets. Designed for demanding utility and industrial applications, UR relays offer flexibility, reliability, and scalability to meet a wide range of power system requirements.

Key Benefits

• Modular Design:
  Common hardware architecture reduces spare parts inventory. Plug-and-play modules simplify installation and lower total system costs.

• Robust Cybersecurity:
  CyberSentry™ UR offers advanced network security aligned with industry standards and compliance requirements.

• Flexible I/O Options:
  Supports high-density I/O, programmable logic, and customization to adapt to diverse application needs.

• IEC 61850-Ready:
  Advanced support for IEC 61850 Editions 1 & 2, including:

• Complete relay settings via SCL files

• Process bus support: IEC 61850-9-2LE, IEC 61869, and HardFiber
  Ensures full interoperability, optimized device management, and lower total cost of ownership.

• Routable GOOSE (R-GOOSE):
  Enables GOOSE messaging across substations for wide-area protection and control schemes.

• Integrated Full-Color HMI:
  Large display with real-time bay mimic, annunciator functions, and phasor graphics for intuitive system visualization and control.

• Triple Ethernet Ports:
  Support for dedicated LAN segments minimizes latency and isolates critical communications from non-critical traffic.

• Phasor Measurement Unit (PMU):
  Built-in synchrophasor capability compliant with IEEE C37.118 (2014) and IEC 61850-90-5. Real-time data streaming directly from the device.
