Description
The UR6NH (often designated in parts catalogs as Module 6N or under the GE Fanuc/GE Vernova automation ecosystem) refers to a high-density, industrial-grade Digital Input/Output (I/O) module engineered for the GE Multilin Universal Relay (UR) series platform (such as the F60, G60, L90, or B90 protection systems).
This module provides the structural physical interface required to loop external binary status indicators (like breaker auxiliary switches or isolator positions) and command outputs into the relay’s high-speed internal programmable logic engine.

Field Application and System Integration Notes
The “Universal Relay” Architecture Context
The GE Multilin UR series relies on a completely modular slot architecture. The base order code of a relay (e.g., G60-N00-HCH-F8F-H6N…) dictates which specific cards populate slots F through M. The UR6NH acts as a drop-in component to expand or replace digital tracking paths when system interlocking requirements increase.
I/O Contact Configuration and Debounce Settings
- Contact Debouncing: Through the GE EnerVista UR Setup Software, each input channel mapped to the UR6NH module can be assigned a specific debounce time (typically 2 to 4 ms). This prevents the relay from interpreting mechanical contact bounce or arc noise from high-voltage switchgear operations as legitimate command signals.
- Trip Output Mapping: If using outputs on this module for direct circuit breaker tripping loops, ensure that external auxiliary suppression circuits or matching current-break ratings are met. Inductive energy arcs generated when breaking a DC breaker trip coil can burn module contacts out over time if not correctly suppressed.
Hot-Swapping Caution
⚠️ Warning: While some modern control cards support online maintenance, it is highly recommended to isolate the auxiliary control power to the UR relay frame before removing or reseating the UR6NH card. Pulling an active I/O module under load can corrupt the backplane serial communication bus or trigger spurious un-intended interlocking commands across the substation automation network.
