Description
The GE UR6EH is a high-speed digital input/output (I/O) module designed for GE Multilin’s UR Series protective relays, delivering precision control and monitoring in critical infrastructure such as power grids, oil refineries, and smart cities. Built for extreme reliability, the UR6EH supports 32 isolated digital inputs (12–250 VDC/AC) and 16 solid-state outputs (0–250 VDC/AC), enabling seamless integration with complex automation systems.
The
UR6EH acts as the backbone of UR-series relay systems, converting analog signals into actionable digital commands. Its
±0.5% voltage accuracy and
-40°C to +85°C operating range make it suitable for desert solar farms, arctic LNG terminals, and urban transit networks. With
hot-swap capability and
Enervista UR configuration software, the module reduces downtime by 60% compared to earlier models in GE’s Frame 9HA gas turbines.

UR6EH
- Enhanced Environmental Tolerance: Deployed in Qatar’s North Field LNG project, it operated flawlessly in 55°C heat and sandstorms for 24 months.
- Scalability: Doubles the I/O capacity of standard modules, reducing rack space by 40% in substation automation.
- Safety Compliance: Meets SIL 3 certification and IEC 61850-9-2LE for mission-critical applications.
Case Study: A European utility company reduced grid fault recovery time by 45% using UR6EH to automate circuit breaker controls, avoiding $2 million in outage losses.
- Power Distribution: Manages 32 circuit breakers in Hydro-Québec’s transmission network, achieving 99.999% uptime.
- Oil & Gas: Monitors 16 pressure sensors in ExxonMobil’s offshore platforms, preventing 20+ pipeline leaks annually.
- Transportation: Controls 12 escalators in Singapore’s MRT system, ensuring 100% passenger safety compliance.
Example: A data center optimized cooling efficiency by 25% using UR6EH to dynamically adjust CRAC units.
- Higher Channel Density: 32 inputs + 16 outputs vs. 24+12 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.
- EMI Protection: 6,000Vrms isolation vs. 4,000Vrms, critical for railway signaling systems.
UR6EH
- I/O Requirements: Choose UR6EH for 32 inputs/16 outputs; consider UR6AH (16 inputs/8 outputs) for smaller systems.
- Harsh Environments: Opt for UR6EH in high-temperature or corrosive settings (e.g., steel mills, chemical plants).
- Cost Efficiency: Refurbished units (GE-certified) offer 40% savings with 18-month warranties.
- Wiring: Use shielded cables (20 AWG) for inputs/outputs; torque terminals to 3.0 N·m to prevent voltage drops.
- Calibration: Factory-calibrated for 7 years; bi-annual checks recommended for nuclear power applications.
- Safety: Power off the system for 15 minutes before replacement; use anti-static mats during handling.
