GE UR6BH Digital Input Output Card for UR Series Relays

Product Overview

The UR6BH Digital I/O Module is a plug-in expansion card for the GE Multilin Universal Relay (UR) platform. It extends relay functionality by providing configurable digital inputs and outputs used for status monitoring, alarm signaling, trip logic, and control commands in protection and control systems.

Designed for high-speed response and electrical robustness, the UR6BH supports hot-swap installation and channel isolation, allowing maintenance or replacement without interrupting relay operation. It is widely deployed in substations, power plants, and industrial electrical networks where deterministic digital signaling is required.

Functional Description

The UR6BH interfaces directly with the UR relay internal bus and operates as a native digital I/O resource within the relay logic engine. Digital inputs can be mapped to breaker status, switch positions, or external alarms, while digital outputs can be configured for trip commands, interlocking, or annunciation.

Its fast response time supports protection schemes that require precise event timing, and integrated diagnostics with LED indicators simplify commissioning and troubleshooting.
