Product Overview

The GE Fanuc 469-P1-HI-A20 is a sophisticated digital relay belonging to the renowned Multilin™ 469 series. It is engineered to provide comprehensive protection, control, and monitoring for medium and large-sized industrial motors. This relay integrates advanced thermal modeling with precise metering capabilities to ensure the longevity and reliability of critical motor assets.

Designed for versatility, the 469-P1-HI-A20 features a robust drawout case design, allowing for rapid replacement and maintenance without disturbing field wiring. It combines high-speed protection algorithms with extensive communication options, making it a central component in modern industrial automation and power management systems.

Key Features & Benefits

  • Advanced Thermal Protection: Utilizes a dynamic thermal model that accounts for thermal capacity used, negative sequence current (unbalance), and RTD inputs to accurately track motor heating and cooling.

  • Drawout Architecture: The unit is housed in a drawout case, facilitating easy removal and installation for maintenance or replacement, minimizing system downtime.

  • High-Precision Metering: Provides accurate real-time monitoring of current, voltage, and power parameters, with four scalable 4-20 mA analog outputs for integration with external control systems.

  • Comprehensive Fault Recording: Capable of storing waveform data (up to 16 cycles) during trip events, aiding in rapid fault diagnosis and root cause analysis.

  • Flexible Communication: Equipped with RS232 and RS485 ports supporting open protocols (Modbus), allowing for seamless integration into SCADA and DCS networks.

  • Versatile Control Power: Supports a wide range of AC and DC control power inputs, ensuring compatibility with various industrial power distribution schemes.
