Product Overview

The GE Multilin UR7CV is a plug-in communications module for the Multilin UR (Universal Relay) platform, used to expand relay connectivity for protection, control, and monitoring systems. Installed in compatible UR relays, the module provides an additional communications interface to support relay-to-relay data exchange and integration with substation/industrial control networks.

UR communication modules like the UR7CV are commonly applied to improve system maintainability by enabling centralized status collection, event reporting, and remote access to relay information through the site’s communication architecture. Final interface type and supported services depend on the relay configuration and installed communication option.

Hardware Parameters

Key Technical Characteristics

• UR-series add-on communications hardware for protection relay connectivity expansion

• Designed for cabinet/relay panel environments, supporting stable operation in utility and industrial electrical rooms

• Supports remote monitoring workflows by enabling networked access to relay data and status (system configuration dependent)

• Service-friendly modular format for maintenance replacement without redesigning the base relay wiring

• Configuration via UR engineering tools typically managed through EnerVista software suite (application dependent)

Industrial Applications

• Substation automation where UR relays require additional communication capability for monitoring and reporting

• Feeder, transformer, and line protection panels using UR relays and external communications infrastructure

• Industrial power distribution in plants requiring relay visibility from SCADA or control room systems

• Retrofit projects adding communications capability to existing UR relay installations without replacing the relay platform
