GE UR6DH Redundant Industrial Protection Relay (Medium-to-High Voltage)

Description

Real-World Use & Application Scenarios
Where is this product used and why?
In GE Multilin protection and control architectures, the UR6DH serves as a flexible digital I/O module that can be deployed to gather input signals from field devices and to drive discrete outputs to actuators, annunciators, or interlock circuits. It is common in medium- and high-voltage protection schemes, industrial automation panels, and distributed control setups where scalable I/O is needed. Utilities and industrial facilities rely on UR-series I/O modules to simplify wiring, improve diagnostic visibility, and enable coordinated protection with other UR modules and protection relays. The eight-channel (or multiple-channel) form is chosen to match the plant’s I/O topology, enabling efficient expansion of the protection and control network while staying within GE’s backplane and EnerVista software ecosystem.

Product Introduction & Positioning
What it is, where it fits, and why it matters
The UR6DH is a Universal Relay digital I/O module designed to integrate into GE’s UR-series protection family. It fits into GE protection racks and provides a robust interface for digital signals, supporting both input and output functions depending on the exact variant. This module is positioned to offer a compact, reliable I/O expansion option for complex protection schemes, helping engineers standardize on GE hardware and leveraging EnerVista for configuration and diagnostics. Its presence in a bill of materials signals a need for scalable, maintainable I/O that can be easily wired to field devices and coordinated with protection logic across the network.
