IS200EGDMH1AGG | General Electric | Ground Detection Module

Overview

The IS200EGDMH1AGG Ground Detection Module by General Electric is a key component in the EX2100 Excitation Control system, responsible for detecting ground conditions in generator field circuits.

Specifications

• Part Number: IS200EGDMH1AGG
• Technology: Surface-mount
• Operating Temperature: -30 to 65°C
• Product Type: Ground Detection Module

Features

• Form Factor: 6U, double-slot, double-height, for space-efficient mounting.
• Mounting: Installed in the Exciter Power Backplane rack (EPBP).
• Ground Detection: Detects leakage resistance between generator field circuit points and ground.
• Redundancy: Single module in simplex systems, three modules in redundant setups for higher reliability.
• Integration: Works with the EXAM module for voltage sensing.
• Signal Management: Coordinates with Master 1 (M1) and Master 2 (M2) for control signals and relay activation.
• Differential Signaling: Sends signals to enable the active master module.
• Oscillator Signal: Converts signals to 50-volt square wave for the Attenuator Module.

LED Indicators

• Power LED: Indicates board power status.
• Master Selection LED: Shows whether the module is the master in a redundant configuration.
• Signal Transmission LED: Indicates the active transmission of the 50-volt signal.
