UR6HH GE Multilin High-Speed Digital I/O Relay Module

Product Overview

The UR6HH Digital I/O Module is a plug-in expansion card for the GE Multilin Universal Relay (UR) platform. It provides additional digital inputs and outputs, enabling the relay to interface with external devices such as circuit breakers, switches, alarms, and control systems in power protection and automation applications.

Designed for fast response and rugged operating conditions, the UR6HH supports hot-swap installation and electrical isolation, allowing maintenance without shutting down the relay. It is commonly deployed in substations, industrial plants, and utility networks where reliable digital signaling is essential.

Functional Description

The UR6HH integrates directly with the UR relay internal bus and is configured through the EnerVista UR software suite. Digital inputs can be assigned to monitor breaker status, interlocks, and alarms, while digital outputs are used for trip commands, control logic, and annunciation.

Its deterministic response time supports protection schemes requiring precise timing, and onboard LED diagnostics provide clear visibility of I/O status and fault conditions.
