GE SR489-P1-HI-A20-E-H is a relay management protection module launched by General Electric(GE),designed for power system protection,equipment monitoring and industrial automation.The following is a comprehensive introduction to the device:

Product Overview

This module belongs to GE’s 489 series generator management relay,which integrates multiple protection functions and communication interfaces,and is suitable for power plants,industrial power systems and energy management scenarios.Its core functions include power protection,status monitoring and remote control,supports RS232 communication protocol,and can be linked with the host computer or other devices.

Core functions and features

Multiple power protection

Provides protection such as overcurrent,undervoltage,ground fault,short circuit,etc.to prevent equipment from being damaged due to abnormal working conditions.

Supports phase sequence protection,stall protection and thermal overload monitoring,suitable for motor and generator management.

Intelligent monitoring and display

Equipped with a 40-character LCD screen,it displays the operating status,alarm information and setting parameters in real time,and supports multi-language interface.

LED indicator intuitively feedbacks the working mode(such as protection/test status),communication activity,reset status,etc.

Communication and remote control

Remote configuration and data transmission through RS232 interface,support integration with monitoring system,and facilitate centralized management.

Optional RS485 interface to expand communication capabilities.

Flexible configuration and high reliability

Support parameter programming(such as protection threshold,time delay)to adapt to different power system requirements.

Adopt anti-interference design,suitable for harsh industrial environments,and pass strict quality testing.

Technical parameters

Control power supply:90-300 VDC or 70-265 VAC(48-62 Hz).

Analog output:4-20 mA for signal transmission.

Input configuration:single-phase CT(P1 model),support external current transformer connection.

Environmental adaptability:enhanced display and chemical protective coating,suitable for high voltage and corrosive environment.

Typical application scenarios

Power plants and power systems

Protect generators,transformers and switchgear,and monitor parameters such as voltage,current,frequency,etc.in real time.

Industrial automation

Control motor start and stop in production lines to prevent overload or mechanical failure.

Energy management

Optimize power distribution,improve energy transmission efficiency,and reduce energy consumption.
