The GE 369-HI-0-M-0-0-0 Motor Management Relay is a digital protective relay designed for comprehensive motor control and monitoring in industrial applications.
Its key functions include:
1. Advanced Motor Protection
Detects and mitigates faults such as overload, current imbalance, phase loss, ground faults, and locked rotor conditions using customizable FlexCurve™ algorithms.
Supports 15 standard thermal curves and user-defined overload profiles for precise motor thermal modeling.
2. Real-Time Monitoring & Diagnostics
Monitors current, voltage, temperature, and power metrics with optional metering kits (e.g., VT/PT inputs for voltage measurement).
Records event logs and fault data for troubleshooting and predictive maintenance.
3. Communication & Control
Features RS232 (front panel) and RS485 (rear ports) with Modbus RTU protocol for SCADA/DCS integration.
Provides analog outputs (4-20mA) and digital I/O for external control systems.
4. Adaptive Motor Learning
Automatically “learns” motor parameters (e.g., inrush current, cooling rates) to optimize protection settings.
Suitable for dual-speed motors and complex mechanical systems.
