Description
GE Fanuc UR8HH Universal Remote I/O Module for Distributed Control Systems
The GE Fanuc UR8HH is a high-performance universal remote I/O module designed for GE’s Series 90-70 and PACSystems, enabling seamless expansion of input/output capabilities in distributed automation networks. With 8 configurable channels supporting analog and digital signals, this module offers flexibility for industrial processes in manufacturing, energy, and infrastructure sectors.
1. Product Overview
The UR8HH acts as a decentralized node in GE’s PLC systems, converting real-world signals (e.g., temperature, pressure, switches) into digital data for centralized control. Its modular design allows fieldbus connectivity (Profibus DP, DeviceNet) and hot-swap functionality, minimizing downtime. Built with IP67-rated enclosure, it withstands dust, moisture, and extreme temperatures (-40°C to +70°C).

3. Advantages & Features
- Multi-Protocol Support: Reduces integration costs by supporting 3 major fieldbuses.
- Diagnostic Capabilities: Real-time LED indicators for channel status and bus errors.
- Longevity: MTBF of 400,000 hours (per GE reliability tests), 20% longer than legacy models.
4. Application Areas & Case Study
- Automotive Plants: Manages robotic welding sensors in Toyota assembly lines.
- Wind Farms: Monitors turbine vibration data for GE Renewable Energy.
- Smart Cities: Controls traffic signal inputs in Singapore’s IoT infrastructure.
Case Study: A BASF chemical plant in Ludwigshafen, Germany, cut wiring costs by 35% using UR8HH modules at remote tank farms, improving monitoring accuracy by 92%.
5. Competitor Comparison
Compared to similar remote I/O solutions:
- Faster Configuration: GE’s Proficy Machine Edition reduces setup time by 40% vs. competitors.
- Higher Flexibility: Supports mixed signal types per channel (e.g., 4 AI + 4 DI), unlike fixed-type alternatives.
- Lower Power Draw: 150mA vs. 220mA average for comparable devices.

6. Selection Recommendations
- Cost-Effective Expansion: Combine with GE’s UR16E for larger I/O requirements.
- Hazardous Areas: Opt for UR8HH-Ex (ATEX-certified) in petrochemical installations.
- Space Optimization: Use UR8HH-S (slim version) in compact control cabinets.
7. Installation & Maintenance Notes
- Network Cabling: Use shielded twisted pair (STP) cables for Profibus DP connections.
- Calibration: Perform annual analog channel checks using GE’s UR Series Configuration Tool.
- Safety: Ensure proper grounding to comply with NEC 501 hazardous location standards.
