General Electric UR6EH Multilin Digital I/O Module

The GE Multilin UR6EH serves as a specialized expansion interface for the Universal Relay (UR) series. It expands the control capabilities of protection systems. This hardware provides a hybrid interface for both monitoring and control. It acts as the bridge between primary power equipment and secondary protection logic.

Technical Performance and Interface Configuration

Core Functionality and System Integration

This module manages real-time status signals from field devices through eight digital inputs. It utilizes four Form-C mechanical outputs for versatile switching operations. Each output supports both normally open and normally closed configurations. Consequently, engineers can implement complex interlocking or tripping logic.

The UR6EH integrates directly into the UR series chassis. It communicates with the central processor module via the internal backplane. This high-speed connection ensures minimal latency for protection actions. Furthermore, the module supports hot-swappable installation in compatible frames.
