Features:

  • GE Multilin UR Series
  • Communications Module
  • High-accuracy metering, diagnostics, and data logging
GE Multilin's UR7KH is a communication module designed specifically for the GE relay series. It enables communication between relays and other UR units, replacing costly traditional copper wire connections. The module provides two relay communication channels, both 1300 nm single-mode laser channels. The module's communication channels enable fast and secure data transmission. Relays can monitor system channels and check system status. Diagnostic data can be displayed, trend analyzed, and exported in EnerVista UR. EnerVista UR is Multilin's industry-leading software and is compatible with GE relay series.

The UR 7KH General Electric Communication Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

The GE Multilin UR-7KH is a high-performance communication module for the Universal Relay (UR) series. It is primarily used to enable fast, secure inter-relay communication, often replacing expensive copper hardwiring in utility and industrial power systems.Powered directly via the UR relay chassis; no separate power supply is required.
  • Oil & Gas and Mining:Protection & management for large induction/synchronous motors
  • Industrial Substation Automation:Communication bridge for coordinated tripping & real-time metering
  • Chemical & Process Plants:UR/7KH pinpoints faults; 1ms voltage dip recording prevents cascading outages
  • Industrial Motors:Prevents thermal overload, broken rotor bars & voltage dips
  • Generators and Transformers:Differential protection & health monitoring for generators/transformers
  • Capacitor Banks:Current/voltage monitoring for single/parallel shunt capacitor banks

Chassis Preparation: Ensure the relay chassis is powered down before attempting to install or remove any module.
Module Insertion: Align the UR-7KH module with the designated slot in the Universal Relay chassis. Slide it in firmly until the plug-in terminal blocks are fully seated.
Secure the Module: Tighten the screws on the module's front plate to ensure a secure mechanical and electrical connection.
Fiber Optic Connection: Connect the 1300 nm single-mode laser fiber cables to the two communication channels. Clean all fiber connectors before insertion to prevent signal attenuation.
