UR6EH | GE Multilin UR Series | Digital I/O Module

Product Overview

The GE UR-6EH is a Digital I/O Module from GE Multilin, designed for the UR Series Universal Relay platform. This module provides 4 Form-C outputs (SPDT changeover contacts) and 8 digital inputs, enabling the relay to control and monitor equipment within substations or protective function devices. The UR-6EH is characterized by the order code "6E", which designates this specific I/O configuration.

Each digital I/O module in the UR series can be differentiated by the type of protection card incorporated into the module. These cards can be classified as Form-A, Form-C, SSR (Solid State Relay), or Fast Form-C. The UR-6EH's Form-C outputs provide greater switching flexibility with normally open (NO), normally closed (NC), and common (C) terminals.

Key Features

• 4 × Form-C outputs (SPDT changeover contacts) for flexible switching
• 8 × Digital inputs for external signal monitoring
• Form-C contact versatility — NO, NC, and Common terminals per output
• Modular plug-and-play design for easy installation and system upgrades
• FlexLogic™ programmable logic support for custom protection schemes
• Compatible with EnerVista UR Setup Software

Technical Specifications

Applications

• Substation automation — breaker status monitoring, interlocking, and control
• Generator and transformer protection — digital I/O expansion for trip and alarm signaling
• Feeder protection — auxiliary equipment control and status indication
• Industrial power systems — control of fans, valves, alarms, and other auxiliary devices
• SCADA integration — status input and command output interfaces

Compatibility

The UR-6EH is fully compatible with the GE Multilin UR Series universal relay family. The module's Form-C outputs provide greater switching flexibility compared to Form-A outputs, making it suitable for applications requiring changeover contacts. 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-6EH 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. Form-C outputs provide NO, NC, and Common terminals for flexible switching.
7. Configuration: Power on and configure via EnerVista UR Setup software.

FAQ

Q: What does the "6E" order code signify?
A: The "6E" designates a digital I/O module with 4 Form-C outputs + 8 digital inputs.

Q: What is the difference between Form-A and Form-C outputs?
A: Form-A is a single normally open (NO) contact. Form-C is a changeover (SPDT) contact with NO, NC, and Common terminals, providing greater switching flexibility.

Q: What is the maximum output current?
A: The UR-6EH Form-C outputs are rated for 2 A maximum output current.

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

Selection Tips

• Choose UR-6EH when you need Form-C changeover contacts (4 outputs) with 8 digital inputs.
• For more Form-C outputs (6 or 8), consider the UR-6CH or UR-6EV.
• For Form-A outputs with current monitoring, consider the UR-6NH.
• Always cross-reference the UR series order code guide before ordering.
