Description

GE 469-P1-HI-A20-W-E

Technical Specifications

  • Operating Voltage Range: 90 to 300 VDC or 70 to 265 VAC at 48-62 Hz.
  • Phase Current Inputs: Opto-isolated inputs, compatible with 1 A phase CT secondaries (denoted by “P1”).
  • Analog Outputs: Four (4) 0 to 1 mA analog outputs.
  • Digital Inputs: 9 opto-isolated digital inputs.
  • Display: Enhanced 40-character LCD display.
  • Operating Temperature: -40°C to +60°C.

Functional Features

  • Provides comprehensive protection against overloads, short circuits, ground faults, and stalling.
  • Features a self-assessment capability to evaluate motor health and provide configurable alerts for rotor problems.
  • Supports communication protocols including RS-232 and Modbus.
  • Equipped with conformal coating for robustness against harsh chemical environments, dust, and moisture.

Application Scenarios
Widely applied in oil and gas, mining, water treatment, power generation, and general manufacturing to protect critical motor equipment.

Performance Parameters

  • High-precision measurement using advanced sensors.
  • Flexible configuration tailored to different motor types and application scenarios.

Material Composition
Industrial-grade electronic components housed in a ruggedized enclosure with a protective conformal polymer layer.

Structural Characteristics
Enhanced faceplate featuring an RS232 port for direct laptop connection, a redesigned keypad, and status indicator LEDs.

Working Principle
Continuously monitors motor parameters (current, voltage, temperature) via CTs and sensors, comparing them against preset thresholds to execute protective actions or transmit data via the EnerVista 469 Setup software.

Installation Requirements

  • Ensure the nominal phase current rating corresponds exactly with the connected 1 A CT secondaries.
  • Connect the RS232 port for configuration using the EnerVista 469 program.

Usage Precautions

  • Mismatched current transformers can cause system damage over time and weaken protection.
  • Utilize the EnerVista software for efficient monitoring rather than manual keypad navigation.
