Description
The GE UR9EH is a high-density digital input/output (I/O) module designed for GE Multilin’s UR Series protective relays, providing scalable control and monitoring in mission-critical industries like power generation, water treatment, and smart manufacturing. Built for rugged environments, the UR9EH supports 64 isolated digital inputs (12–250 VDC/AC) and 32 solid-state outputs (0–250 VDC/AC), enabling seamless integration with complex automation systems.
The
UR9EH serves as the central hub for UR-series relay systems, converting analog signals into precise digital commands. Its
±0.3% voltage accuracy and
-40°C to +85°C operating range make it suitable for offshore wind farms, nuclear reactors, and automotive assembly lines. With
hot-swap capability and
Enervista UR configuration software, the module reduces maintenance downtime by 70% compared to legacy systems in GE’s LM6000 aeroderivative gas turbines.

UR9EH
- Extreme Scalability: Doubles the I/O capacity of the UR6EH, reducing rack space by 50% in large-scale solar farms.
- Enhanced Safety: SIL 3 certification and IEC 61850-9-2LE compliance ensure reliability in nuclear power plants.
- EMI Resistance: 8,000Vrms isolation (vs. 6,000Vrms for standard modules), critical for railway signaling systems.
Case Study: A Middle Eastern utility company reduced grid fault detection time by 60% using UR9EH to automate 64 circuit breakers, preventing $3.5 million in annual outage losses.
- Power Generation: Manages 64 generator protective relays in GE’s 7HA.03 gas turbines, achieving 99.998% uptime.
- Water Treatment: Monitors 32 pump controls in Singapore’s NEWater facilities, optimizing energy efficiency by 30%.
- Manufacturing: Controls 64 robotic arms in Tesla’s Gigafactory, reducing assembly errors by 45%.
Example: A semiconductor plant reduced downtime by 80% using UR9EH to monitor 32 wafer fabrication tools.
- Higher Channel Density: 64 inputs + 32 outputs vs. 48+24 for most alternatives, ideal for space-constrained projects.
- Extended Voltage Range: 12–250 VAC/DC vs. 24–125 VAC/DC standard, compatible with legacy and modern systems.
- Faster Response: ≤2 ms input latency vs. ≤5 ms industry average, critical for high-speed automation.
UR9EH
- Large-Scale Systems: Choose UR9EH for 64 inputs/32 outputs; consider UR6EH (32 inputs/16 outputs) for smaller projects.
- Harsh Environments: Opt for UR9EH in extreme temperatures (e.g., steel mills, desert solar farms).
- Cost Efficiency: Refurbished units (GE-certified) offer 45% savings with 24-month warranties.
- Wiring: Use 18 AWG shielded cables for inputs/outputs; torque terminals to 3.5 N·m to prevent voltage drops.
- Calibration: Factory-calibrated for 10 years; annual checks recommended for aerospace applications.
- Safety: Power off the system for 20 minutes before replacement; use anti-static wrist straps during handling.
