GE UR6AH High-Speed Digital I/O Module for Industrial Automation
The GE UR6AH is a versatile digital input/output (I/O) module designed for GE Multilin’s UR Series protective relays, delivering real-time control and monitoring in power generation, water treatment, and smart manufacturing. Optimized for harsh industrial environments, the UR6AH supports 16 isolated digital inputs (24–250 VDC/AC) and 8 solid-state outputs (0–250 VDC/AC), enabling seamless integration with sensors, actuators, and control systems.
1. Product Overview
The UR6AH acts as the “nervous system” of UR-series relay systems, converting analog signals into digital commands for automation processes. Its ±1% voltage accuracy and -40°C to +70°C operating range make it ideal for steel mills, wastewater plants, and offshore platforms. With hot-swap capability and Enervista UR configuration software, the module reduces commissioning time by 50% compared to legacy solutions in GE’s LM6000 gas turbines.

3. Key Advantages
Extreme Environment Resilience: Deployed in ArcelorMittal’s steel plants, it withstood 100°C ambient temperatures and 90% humidity for 3 years with 0 failures.
Flexible Configuration: Customizable input/output mapping reduces wiring costs by 30% in complex systems.
Safety Compliance: Meets SIL 3 certification for critical applications, ensuring 99.999% reliability.
Case Study: A North American wastewater plant reduced pump downtime by 35% using UR6AH to automate sludge level controls, saving $800,000 annually.
4. Applications & Use Cases
Power Generation: Controls 16 boiler valves in EDF’s thermal plants, achieving ±0.5% positioning accuracy.
Water Treatment: Monitors 12 chlorine sensors in Suez’s facilities, preventing 10+ chemical overdosages monthly.
Example: A semiconductor fab reduced energy costs by 20% using UR6AH to schedule cleanroom fans dynamically.
5. Competitor Comparison
Higher Channel Density: 16 inputs + 8 outputs vs. 12+6 for most alternatives, ideal for large-scale projects.
Extended Voltage Range: 24–250 VAC/DC vs. 24–125 VAC/DC standard, suitable for mixed-voltage environments.
EMI Protection: 4,000Vrms isolation vs. 2,500Vrms, critical for motor control centers.

6. Selection Recommendations
I/O Density: Choose UR6AH for 16 inputs/8 outputs; opt for UR6BH (32 inputs/16 outputs) for higher density.
Harsh Environments: Use UR6AH in corrosive or high-vibration settings (e.g., chemical plants, mines).
Budget: Refurbished units (GE-certified) save 35% while retaining 12-month warranties.
7. Installation & Maintenance Notes
Wiring: Use stranded wires (18–22 AWG) for inputs/outputs; torque terminals to 2.5 N·m to prevent contact issues.
Calibration: Factory-calibrated for 5 years; annual checks recommended for medical/pharmaceutical applications.
Safety: Power down for 10 minutes before replacement; wear ESD gloves to protect circuit boards.
