GE Multilin UR6HH UR 6HH Direct I/O Module

Product Overview

The GE UR-6HH is a Digital I/O Module from GE Multilin, designed for the UR Series Universal Relay platform. This module provides 6 Form-A outputs (no monitoring) and 4 digital contact inputs, enabling the relay to connect to various devices in the operating system such as selector switches, pushbuttons, limit switches, fans, lights, and valves.

The UR-6HH supports both wet and dry contact types. Dry contacts provide isolation between devices, while wet contacts do not. The module is fully compatible with EnerVista UR software for streamlined configuration and diagnostics.

Key Features

• 6 × Form-A outputs (normally open, no monitoring) for direct control applications
• 4 × Digital contact inputs for external signal monitoring
• Supports both wet and dry contact types
• Modular plug-and-play design for easy installation and upgrades
• FlexLogic™ programmable logic support for custom protection schemes
• Compatible with EnerVista UR Setup Software

Technical Specifications

Applications

• Industrial automation — process control systems and building management
• Power generation — monitoring and control of auxiliary equipment
• Oil and gas — data acquisition and equipment control
• Water and wastewater — pump and valve control
• Substation automation — status monitoring and interlocking logic

Compatibility

The UR-6HH is fully compatible with the GE Multilin UR Series universal relay family. Modules can be mixed within the same chassis for scalable system upgrades. Always ensure replacement modules match the original type and order code to prevent hardware mismatch errors.

Installation Guide

1. Power Down: Completely de-energize the UR relay chassis. Never install or remove modules while energized.
2. ESD Protection: Wear a grounded ESD wrist strap before handling the module.
3. Slot Verification: Confirm the target slot is empty and matches the module orientation.
4. Module Insertion: Slide the UR-6HH into the chassis guide rails, aligning the rear terminal block with the backplane connector.
5. Secure Mounting: Tighten the faceplate retention screws to the specified torque.
6. Wiring: Connect field wiring per the UR series wiring diagram. Observe correct polarity.
7. Configuration: Power on and configure via EnerVista UR Setup software.

FAQ

Q: What does the "6H" order code signify?
A: In the UR series order code structure, "6H" designates this specific digital I/O module configuration: 6 Form-A outputs + 4 digital inputs.

Q: What is the difference between wet and dry contacts?
A: Dry contacts are passive contacts that provide isolation between devices. Wet contacts are active contacts that do not provide the same isolation.

Q: Can I use UR-6HH for breaker tripping?
A: The Form-A outputs can be used for control applications. For high-current tripping, verify contact ratings or consider trip-rated modules.

Q: Is hot-swapping supported?
A: No. Always remove control power before installing or removing any module.

Selection Tips

• Choose UR-6HH when you need 6 Form-A outputs with 4 inputs for general-purpose control.
• For Form-A outputs with current monitoring, consider the UR-6NH.
• For all Form-C outputs, consider the UR-6CH.
• Always cross-reference the UR series order code guide before ordering.
