UR6BH | GE Multilin UR Series | Digital I/O 6B Card

Product Overview

The GE UR-6BH is a Digital I/O Module from GE Multilin, designed for the UR Series Universal Relay platform. This rugged, rack-mounted interface provides high-density binary sensing and control, bringing powerful digital I/O capabilities into the UR protection platform. The UR-6BH features eight independent Form-A outputs, each rated for 30 A make and 15 A continuous carry, allowing the module to drive lock-out relays, annunciators, breaker coils, and other high-energy loads without external interposing hardware.

Every output point is fully isolated, opto-coupled, and surge-tested to 2.5 kV, ensuring that noisy substation environments or fast-rise fault currents cannot corrupt adjacent circuits. Status is reported with 1 ms time-stamping accuracy via the UR's high-speed internal bus, so event records reflect exactly when a breaker auxiliary contact closed or a trip contact opened.

Key Features

• 8 × Form-A outputs (normally open) with high current capacity
• 30 A make / 15 A continuous carry per output — drives high-energy loads directly
• Fully isolated, opto-coupled outputs with 2.5 kV surge protection
• 1 ms time-stamping accuracy for precise event recording
• Front-facing green/red LEDs for immediate coil health confirmation
• Automatic module recognition by EnerVista UR software
• Hot-swappable construction for expansion or replacement without rebooting
• Compatible with EnerVista UR Setup Software

Technical Specifications

Applications

• Breaker tripping and lock-out relay control
• Annunciator and alarm signaling
• High-energy load switching without external interposing relays
• Substation automation — status monitoring and control
• Event recording and sequence-of-events (SOE) with 1 ms precision

Compatibility

The UR-6BH is fully compatible with the GE Multilin UR Series universal relay family. The module is automatically detected by EnerVista UR software, which assigns logic variables and scales de-bounce filters to match the application. Modules can be mixed within the same chassis for scalable system upgrades.

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-6BH 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 high-current output wiring per the UR series wiring diagram. Use appropriate wire gauge for 30 A make capacity.
7. Configuration: Power on and configure via EnerVista UR Setup software. The module is automatically recognized.

FAQ

Q: What does the "6B" order code signify?
A: The "6B" designates a digital I/O module with 8 Form-A outputs with monitoring and high current capacity (30 A make / 15 A carry).

Q: Can the UR-6BH drive breaker coils directly?
A: Yes. With 30 A make and 15 A continuous carry ratings, the UR-6BH can drive lock-out relays, annunciators, and breaker coils without external interposing hardware.

Q: What is the time-stamping accuracy?
A: The UR-6BH provides 1 ms time-stamping accuracy via the UR's high-speed internal bus, ensuring precise event records.

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

Selection Tips

• Choose UR-6BH when you need high-current Form-A outputs (30 A make) for direct breaker tripping and high-energy load control.
• For standard Form-A outputs without monitoring, consider the UR-6HH or UR-6TH.
• For Form-C outputs, consider the UR-6CH or UR-6EV.
• Always cross-reference the UR series order code guide before ordering.
