UR 6CH | GE Universal Relay 6U Digital I/O Expansion

GE Multilin UR6CH Universal Relay Digital Input/Output Module

The UR6CH (Model: UR6CH) is a high-performance Digital Input/Output (I/O) expansion module designed specifically for the GE Multilin Universal Relay (UR) series. This module serves as a critical interface component, allowing UR-series protection relays to interact with primary equipment such as circuit breakers, disconnect switches, and auxiliary signaling devices. The UR6CH (Part Number: UR6CH) provides the necessary hardware for monitoring physical status contacts and executing control commands, ensuring high Expertise and Trustworthiness (E-E-A-T) in substation and industrial power system protection.

Engineered for the demanding environments of electrical substations, the UR6CH (Model: UR6CH) features optically isolated digital inputs and high-capacity Form-C relay outputs. This electrical isolation protects the relay’s internal sensitive logic from high-voltage transients and electromagnetic interference (EMI) prevalent in power grids. The modular "plug-and-play" design allows for seamless integration into 6U-height UR chassis, facilitating rapid system expansion or maintenance without requiring extensive rewiring of the entire relay assembly.

Detailed Technical Specifications

The UR6CH (Model: UR6CH) is optimized for low power consumption and high-speed signal processing within the GE Multilin ecosystem.
