Details
1. Product Overview
GE 369-HI-R-B-O-P-H-E is a flagship motor management digital relay under GE's Multilin series, specifically designed for full-lifecycle protection, precise control, and intelligent monitoring of industrial motors. With a microprocessor as its core and a modular architecture, it can real-time collect the electrical and mechanical status of motors. Through customized protection logic, it minimizes downtime risks, extends motor service life, and serves as a core safety unit in industrial automation systems.
2. Key Technical Specifications
1. Electrical Specifications
- Control Power Supply: 50-300 VDC or 60-264 VAC (compatible with global industrial power supply standards)
- Current Input: Phase current 1A/5A (secondary CT input); ground current detection frequency 20-100Hz

- Overload Capacity: Withstands 150% overload for 1 minute (handles motor startup inrush current)
2. Communication & Integration
- Interfaces: 1 front-panel RS232 port, 3 rear-panel RS485 ports; Ethernet expansion supported for selected models
- Protocols: Supports Modbus RTU/TCP and DNP3 protocols, enabling seamless integration with SCADA (Supervisory Control and Data Acquisition)/DCS (Distributed Control Systems)
- Programmability: Built-in soft PLC (Programmable Logic Controller), supporting custom logic and protection curve configuration
3. Environmental & Physical Characteristics
- Operating Environment: Temperature -40°C to +60°C, relative humidity 95% (non-condensing)
- Storage Environment: Temperature -40°C to +80°C
- Installation Method: Standard DIN rail mounting; metal flame-retardant enclosure, IP30 protection rating for cabinet-mounted installation
- Dimensions & Weight: Approximately 292×140×216 mm (H×W×D); unit weight approximately 3.6 kg
4. Certifications & Safety
- Certifications: Compliant with CE, UL, and CSA certifications; IEC 61850 communication standard compatibility available as an option for selected models
- EMC (Electromagnetic Compatibility): Compliant with EN 61000 standard (resistant to strong electromagnetic fields and high-current interference)
3. Core Functions & Advantages
1. Comprehensive Protection
- Electrical Protection: 12 types of protection functions including overcurrent, undercurrent, overvoltage, undervoltage, short circuit, and ground fault
- Thermal Protection: Combines I²t thermal modeling (Function 49) with direct RTD temperature measurement to prevent motor burnout due to overheating
- Mechanical Protection: Equipped with jam detection, reverse rotation alarm, and bearing temperature anomaly early warning functions
- Customized Protection: 8 programmable protection curves, suitable for different motor types such as induction motors and synchronous motors
2. Intelligent Monitoring & Diagnosis
- Real-Time Data: Monitors over 20 parameters including current, voltage, power, frequency, and energy consumption (kWh/MWh)
- Event Tracing: Stores 512 historical events (including fault type, time, and waveform data), supporting waveform capture of 16 cycles before tripping
- Health Report: Generates motor health scores, predicts maintenance cycles, and reduces unplanned downtime
3. Flexible Control & Integration
- Control Modes: Supports local keypad control, remote communication control, and logical linkage control
- Expansion Capability: Modular I/O (Input/Output) design, allowing addition of analog/digital modules to meet customized requirements
- HMI (Human-Machine Interface): 40-character LCD (Liquid Crystal Display) with navigation keys, supporting on-site parameter configuration and fault query
4. Operating Principle
Operates based on a closed-loop mechanism of "Signal Acquisition - Logic Judgment - Protection Execution - Data Feedback":
- Signal Acquisition: Collects electrical and temperature signals via CT (Current Transformer), PT (Potential Transformer), and RTD, then converts them into digital quantities through A/D (Analog-to-Digital) converter;
- Data Processing: The microprocessor compares real-time data with preset thresholds to identify abnormal conditions such as overcurrent and overtemperature;
- Protection Execution: Fault trigger response time is only 0.1 ms, cutting off motor power supply or issuing an alarm signal, while initiating waveform capture and event recording;
- Data Feedback: Uploads fault data and real-time parameters to the SCADA system via communication protocols, supporting remote reset and parameter adjustment.
5 . Sizing & Services
- Compatible Motors: AC induction/synchronous motors with rated voltage ≤10 kV and rated current ≤630 A
- Value-Added Services: Provides EnerVista 369 configuration software, supporting remote debugging, data export, and firmware update
- Warranty Services: 2-year global warranty, with on-site maintenance and technical support provided by GE's global service network
