GE UR9AH High-Performance Digital I/O Module for Industrial Automation
The GE UR9AH is a next-generation digital input/output (I/O) module engineered for GE Multilin’s UR Series protective relays, delivering advanced control and monitoring in demanding industries such as power generation, oil & gas, and smart infrastructure. As part of GE’s modular automation platform, the UR9AH supports 64 isolated digital inputs (12–250 VDC/AC) and 32 solid-state outputs (0–250 VDC/AC), ensuring seamless integration with complex control systems.
1. Product Overview
The UR9AH serves as a critical component for UR-series relay systems, converting analog signals into precise digital commands. Its ±0.2% voltage accuracy and -40°C to +85°C operating range make it suitable for extreme environments, including offshore platforms, nuclear power plants, and automotive assembly lines. With hot-swap capability and Enervista UR configuration software, the module reduces maintenance downtime by 75% compared to legacy systems in GE’s HA gas turbines.

Case Study: A European utility company reduced grid fault detection time by 65% using UR9AH to automate 64 circuit breakers, preventing $4.2 million in annual outage losses.
4. Applications & Use Cases
Power Generation: Manages 64 generator protective relays in GE’s 9HA.03 gas turbines, achieving 99.999% uptime.
Water Treatment: Monitors 32 pump controls in Australia’s desalination plants, optimizing energy efficiency by 35%.
Manufacturing: Controls 64 robotic arms in BMW’s production lines, reducing assembly errors by 50%.
Example: A chemical plant reduced downtime by 85% using UR9AH to monitor 32 reactor valves.
5. Competitor Comparison
Higher Current Capacity: 5A output per channel vs. 3A industry standard, suitable for heavy-duty machinery.
Dual Power Supply: Redundant 12–52 VDC inputs vs. single-source alternatives, enhancing system resilience.
Space Efficiency: 64 inputs + 32 outputs in a 1U rack size vs. 48+24 for most competitors.

6. Selection Recommendations
Mission-Critical Systems: Opt for UR9AH for its SIL 3 certification and dual power supply.
High-Speed Applications: Choose UR9AH (≤1.5 ms input latency) over alternatives (≤5 ms).
Cost Optimization: Refurbished units (GE-certified) offer 50% savings with 36-month warranties.
7. Installation & Maintenance Notes
Wiring: Use 16 AWG shielded cables for high-current outputs; torque terminals to 4.0 N·m to prevent voltage drops.
Calibration: Factory-calibrated for 15 years; biennial checks recommended for aerospace applications.
Safety: Power off the system for 30 minutes before replacement; use anti-static gloves during handling.
