GE IS200EGDMH1AFF | EX2100 EGDM Exciter Ground Detect Module Mark VI Speedtronic

IS200EGDMH1AFF is the Exciter Ground Detect Module (EGDM), a plug‑in printed‑circuit board manufactured by General Electric for GE Speedtronic Mark VI and EX2100 generator excitation control systemsMOORE AUTO…. This board continuously monitors field‑winding ground‑fault leakage current on both AC and DC sides of the exciter field circuit, detecting insulation degradation and field‑to‑ground faults for synchronous generators.

It communicates fault‑warning and trip status back to the Mark VI main controller via the rack backplane. In simplex EX2100 configurations one EGDM board is deployed; redundant M1/M2/M3 EX2100 systems require three EGDM modules for fault‑voting logicMOORE AUTO…. Power plants procure IS200EGDMH1AFF for scheduled outage overhaul, unplanned fault repair, EX2100 system retrofits and critical MRO spare stocking. OEM series production is discontinued; worldwide supply is limited to new‑old‑stock surplus and fully refurbished functionally‑tested units.

Key Features

• Dedicated EGDM hardware for GE EX2100 excitation platform, direct VME‑style backplane insertion into Mark VI rack slots, no external adapter neededMOORE AUTO…
• Real‑time exciter field ground‑leakage detection for AC and DC field circuits, identifies winding insulation deterioration and ground fault conditions
• Supports simplex single‑board operation and triple‑redundant 3‑board voting architecture for high‑availability generator protection schemesMOORE AUTO…
• Conformal‑coated industrial PCB assembly with surge suppression and EMI filtering, stable operation in high‑noise power‑plant cabinet environments
• Interfaces with the EXAM auxiliary monitor module for extended ground‑fault diagnostic coverage
• Reports leakage magnitude and fault alarms over Mark VI backplane bus, enabling controller logic to trigger warnings or excitation‑system trip commands
• Static‑sensitive rack‑mount card, supports fast module swap‑out during planned unit shutdowns
• Built‑in self‑diagnostic routines to flag internal board hardware anomalies to the HMI alarm list

4. Power‑plant emergency repair after exciter‑field ground‑fault events
5. Legacy EX2100 system retrofits and spare‑part stocking for simplex and triple‑redundant excitation architectures

Compatibility Notes

IS200EGDMH1AFF is a revision variant within the EGDM family. It must be matched against your EX2100 hardware revision, rack firmware version and original project BOM before ordering replacement hardware. Do not confuse this EGDM ground‑detect board with IS200EGDMH1ADF (exciter gate‑driver board); these two carry different hardware functions and are not drop‑in interchangeable. Other related EX2100 family boards include IS200ECTBG1ADE, IS200EGPAG1 series; confirm full part‑number suffix revision to avoid mismatch.

Product Condition & Supply Information

Original GE manufacturing for IS200EGDMH1AFF has been discontinued. Available stock consists of new‑old‑stock surplus and fully refurbished assemblies. Every unit should complete comprehensive bench testing prior to shipment, including ground‑leakage simulation test, backplane communication validation, self‑diagnostic check and fault‑alarm‑output verification.
