Description
GE Multilin 369-HI-R-M-0-0-H-E Motor Management Relay
The 369-HI-R-M-0-0-H-E is a high-performance motor protection and management relay designed for industrial applications requiring advanced motor monitoring and control. Part of GE Multilin’s 369 series, this relay combines robust protection features with communication capabilities to ensure reliable operation in harsh environments.
1. Product Overview
The 369-HI-R-M-0-0-H-E monitors and protects medium-sized motors against faults (e.g., overcurrent, ground faults, phase unbalance) while providing real-time performance data for predictive maintenance. Its self-learning algorithms adapt to motor parameters, enabling optimal protection without manual configuration. With 110–250 VDC/100–240 VAC control power compatibility and conformal coating for corrosion resistance, this relay is ideal for diverse industrial settings. Key features include Modbus RTU communication and Class I, Division 2 certification for hazardous areas.

- Flexible Configuration: Programmable analog outputs (0–20 mA) and digital inputs adapt to custom control logic.
- Safety Compliance: Class I, Division 2 certification ensures operation in explosive atmospheres like oil refineries.
- Ease of Use: Intuitive LCD interface and keypad simplify parameter adjustment and diagnostics.
Case Study: A U.S. wastewater plant reduced motor failures by 35% using the 369-HI-R-M-0-0-H-E to detect bearing wear through vibration analysis.
4. Applications & Use Cases
- Industrial Machinery: Protects pumps, fans, and compressors in manufacturing plants.
- Power Generation: Monitors auxiliary motors in gas turbines and wind farms.
- Water Treatment: Controls motors in pumping stations and sludge agitators.
Example: A German steel mill deployed 369-HI-R-M-0-0-H-E to protect 50+ motors, cutting maintenance costs by $150,000 annually.
5. Competitor Comparison
- Higher RTD Capacity: Supports 12 RTD inputs vs. 8 in comparable relays, ideal for complex machinery.
- Cost Efficiency: 20% lower cost per channel than alternatives for multi-motor systems.
- Environmental Resilience: Conformal coating outperforms standard PCB protection in dusty or humid environments.

6. Selection Recommendations
- Voltage Compatibility: Choose 369-HI-R-M-0-0-H-E for 110–250 VDC/AC systems; use 369-HI-R-L for 24 VDC applications.
- Hazardous Areas: Opt for this model’s Class I Div 2 certification over non-rated alternatives.
- Retrofit Needs: Replace older GE Multilin 8 series relays with minimal wiring changes.
7. Installation & Maintenance Notes
- Mounting: DIN rail or panel-mount in flame-retardant enclosures.
- Cabling: Use shielded twisted-pair cables for RTD inputs to minimize EMI.
- Calibration: Factory-calibrated; update via GE EnerVista software every 2 years.
- Troubleshooting: Front-panel LEDs indicate power, communication, and fault status.
