The GE IS200EGDMH1AGG, also cataloged as the IS200EGDMH1AGG Exciter Ground Detection Module, serves as a double-slot, double-height (6U) board within the EX2100 Excitation Control System. It detects ground paths from exciter components connected to generator field wiring, operating with simplex or triple modular redundant configurations depending on system design.
Mounting: Control power supply module in control cabinet
Backplane Bus Communication Velocity
The IS200EGDMH1AGG integrates with the EX2100 backplane, ensuring deterministic communication across simplex and redundant systems. Signal acquisition is performed via a sense resistor and differential amplifier, followed by an A/D converter and voltage-controlled oscillator. Fiber-optic transmission to the EISB option board maintains low latency and high noise immunity. Firmware flash compatibility supports synchronized updates without interrupting ground detection.
Frequently Asked Questions (FAQ)
Q: Does the IS200EGDMH1AGG support hot-swap installation? A: No. The module requires system shutdown before removal or insertion to maintain ground detection integrity.
Q: How many EGDM modules are required in redundant systems? A: Triple modular redundant systems typically use three EGDM boards, while simplex systems use one.
Q: What protective measures are applied to the PCB? A: The board is coated with conformal PCB coating, enveloping all components for environmental and electrical protection.
Field Installation Guidelines
Install the module in the designated control cabinet slot with secure connector engagement.
Ensure fiber-optic transmitter alignment when interfacing with the EISB option board.
Maintain shielded routing for ground sense resistor connections to minimize interference.
Verify insulation integrity of field wiring before energization.
Observe mechanical clearance for double-slot, double-height form factor during cabinet integration.
