Overview
The GE Multilin 269PLUS-100P-120VAC is a microprocessor-based motor management relay designed to protect and manage AC motors of various sizes and characteristics. This digital relay combines advanced thermal modeling with adaptive learning to optimize protection for individual motor applications. The 269PLUS series is widely used in industrial facilities requiring dependable motor supervision and fault detection.
Key Features
- Adaptive Learning Technology: The relay learns individual motor parameters including inrush current, negative sequence current, cool-down rates, and acceleration time to improve protection accuracy over time.
- Comprehensive Fault Detection: Monitors thermal overload, phase unbalance, phase loss, stall, and locked rotor conditions with latched trip, alarm, and two auxiliary programmable relays.
- Thermal Modeling: Calculates real-time motor I²t thermal stress based on actual load current and stator RTD feedback for precise thermal protection.
- Front-Panel Interface: 48-character alphanumeric display with 12-position keypad for parameter setup, monitoring, diagnostics, and troubleshooting.
- RS-485 Communication: Optional meter communication port for remote monitoring and integration with control systems and supervisory software.
- Flexible Configuration: Multiple relay contact options and fail-safe codes allow customization for different application requirements.
