GE UR-6GV Digital Output Expansion Module

GE Multilin UR 6GV Digital Output Expansion Module

The GE Multilin UR 6GV is a dedicated digital output expansion module for the Universal Relay (UR) family. It increases the relay’s ability to drive external devices such as breakers, interlocks, alarms, and control circuits. As part of the modular UR architecture, the 6GV module installs into one of the relay’s rear slots and provides additional Form‑A / Form‑C output capability depending on the relay’s order code.

Hardware Specifications

Functional Description

The UR‑6GV module expands the digital output capability of UR relays such as:

• L60 Line Phase Comparison
• T60 Transformer Protection
• C30 / C60 Centralized I/O Processors
• B30 Bus Differential
• F35 Feeder Protection

The module provides additional output contacts used for:

• Breaker trip commands
• Alarm signaling
• Interlocking logic
• Auxiliary control functions
• External device actuation

Output contacts may be:

• Form‑A (NO)
• Form‑C (changeover)

The exact mix depends on the relay’s order code. The 6GV module integrates seamlessly with EnerVista UR, allowing configuration, monitoring, and diagnostics through Viewpoint Monitoring and Viewpoint Maintenance.

Typical Output Applications

• Breaker trip / close signals
• Lockout relay activation
• Alarm annunciation
• Motor or transformer auxiliary control
• Interlocking schemes
• External permissive signals

The module’s contacts are designed for high‑reliability operation in protection‑grade environments.

Placement Within a UR Relay

The location of the UR‑6GV module inside a relay depends on:

• The relay type (e.g., B30, C30, T60)
• The order code segment (e.g., 6G, 6V, 6H)
• The number of digital output modules installed

Example: In a relay order code such as:

B30‑H00‑HCL‑F8H‑H6H‑L8H‑N6A‑S8H‑U6H

A segment like 6G or 6V indicates a digital output module installed in that slot.

Frequently Asked Questions

Q: What does the UR‑6GV module do? A: It expands the relay’s digital output capability, providing additional Form‑A or Form‑C outputs for tripping, signaling, and control.

Q: How is the UR‑6GV configured? A: Through EnerVista UR, using Viewpoint Monitoring and Viewpoint Maintenance tools.

Q: What types of contacts does the UR‑6GV support? A: Depending on the order option, it may support Form‑A or Form‑C outputs.

Q: Where is the UR‑6GV located inside a UR relay? A: Its slot position is determined by the relay’s order code. Each two‑digit code (e.g., 6V) identifies the module’s location.

Field Installation Guidelines

• Ensure the module is fully seated in the UR chassis to maintain reliable output‑signal timing.
• Separate digital output wiring from CT/VT circuits to reduce noise coupling.
• Use shielded wiring for long‑distance control circuits.
• Confirm contact type requirements before installation (Form‑A vs. Form‑C).
• Verify connector engagement before energizing the relay.
