GE UR7KH PLC Module

 

The GE UR7KH PLC Module is a high-performance communication module designed for the GE Multilin Universal Relay (UR) platform. It plays a key role in enabling high-speed data exchange and inter-relay communication, replacing traditional hardwired connections and significantly improving system efficiency.

From a customer perspective, the UR7KH provides reliable fiber-optic communication, reduced wiring complexity, and enhanced system flexibility, making it ideal for modern power automation systems. With dual communication channels, it ensures fast, secure, and stable data transmission between relays and control systems.

Its integration with GE's EnerVista software allows users to monitor system health, analyze communication performance, and quickly diagnose issues-helping reduce downtime and maintenance costs

Inter-relay communication
Fiber-optic data transmission
Real-time system data exchange
Communication channel monitoring
Alarm triggering for communication faults

• Modular architecture: Common hardware reduces spare parts inventory; plug-and-play modules reduce maintenance costs and simplify operation (Multilin UR)

• Proven flexibility and customization capabilities make Multilin UR/URPlus devices suitable for retrofitting virtually any type of legacy protection and control (P&C) system

• Large human-machine interface (HMI) and alarm panel provide local monitoring and can serve as a backup for substation HMIs

• Phase measurement units (synchronous phasors) comply with IEEE® C37.118 (2011) and IEC® 61850-90-5 standards, allowing data to be transferred directly from your protection devices

• Built-in IEEE 1588 time synchronization protocol support eliminates the need for separate wiring for P&C devices (Multilin UR)

• Two certified advanced IEC 61850 Ed. 1 and Ed. 2 implementations: 2 standards, complete setup via SCL files, and comprehensive process bus support (IEC) • IEC 61850-9-2LE, IEC 61869, or IEC 61850-9-2 (hard fiber) ensures interoperability, optimizes equipment management, and reduces total cost of ownership.

• Routable GOOSE (R-GOOSE) enables users to send GOOSE messages outside the substation, supporting WAPC for wide-area applications and building a more cost-effective communication architecture.

• Improved network availability by reducing failover time to zero through support for IEC® 62439-3 "PRP".

• Support for IEEE C37.111-1999/2013 and IEC 60255-24 Ed 2.0 COMTRADE standards.

The UR7KH module is widely used in industries where reliable communication is critical:

Power Generation Plants
