GE IS200AEPGG1AAA | AEPG Control Module for Wind Turbine Systems

Technical Specifications

The available technical description specifically notes the P1-to-HW1 wire arrangement, FU1 fuse, diode protection, mounting holes, and compact board construction.

Product Overview

The GE IS200AEPGG1AAA is an AEPG module printed circuit board associated with the GE Energy Mark VIe Wind turbine control platform. GE catalog references identify the base IS200AEPGG1A as an AEPG module board, placing it within the Mark VIe Wind control hardware family.

The GE IS200AEPGG1AAA is a compact board rather than a conventional multi-channel PLC I/O card. Available hardware inspection data shows a single primary P1 connector, with two wires routed from P1 to the HW1 connection on the board. The conductors are identified as B and W, corresponding to positions 1 and 2 at P1. The board also includes a FU1 fuse and associated diode protection.

The GE IS200AEPGG1AAA should therefore be evaluated as an exact Mark VIe Wind hardware assembly. Several secondary-market pages incorrectly classify this part as a general analog I/O or auxiliary-generator control board and publish unsupported channel counts and voltage ratings. Those claims conflict with the more specific AEPG identification and physical hardware description.

Main Features & Field Considerations

Mark VIe Wind application
The AEPG designation is associated with GE’s Mark VIe Wind turbine control hardware. GE-related component catalogs list IS200AEPGG1A alongside other Mark VIe Wind boards such as AEPB and AEPA assemblies.

Compact PCB construction
The board is unusually small compared with many GE turbine-control boards. Available inspection information gives an approximate PCB footprint of 4 × 1 inches, while additional clearance is required for the attached wire arrangement.

P1 / HW1 interconnection
The two-wire loop between P1 and HW1 is one of the most useful visual identification characteristics. The wires are marked B and W at HW1 and 1 and 2 at P1. This should be checked against the replacement board before installation.

Fuse and protection circuit
The board contains a FU1 fuse and a diode used for voltage protection. If a removed board shows a blown FU1, replacing the board without determining why the fuse opened can result in repeat failure.

Revision identification matters
The complete number IS200AEPGG1AAA should be used for procurement. GE’s part-number convention distinguishes the base assembly designation from additional revision and configuration fields, so shortening the number to IS200AEPGG1A can lose useful identification information.

Important Specification Warning

There is poor-quality and contradictory third-party data for this part.

One listing describes the board as a Mark VIe Wind AEPG module and provides physical-board observations that are consistent with the available hardware information.

Other listings incorrectly describe IS200AEPGG1AAA as a Mark V analog I/O board with eight analog inputs, six relay outputs, 24 VDC supply, and generator excitation functions. I would not use those specifications for engineering or replacement decisions.

The safer classification is:

GE Energy — AEPG Module PCB, Mark VIe Wind

Procurement Description

GE Energy — Mark VIe Wind AEPG Module PCB, Functional Revision A, P1/HW1 Wire Interface, FU1 Fuse and Diode Protection

For a like-for-like replacement, specify the , not merely “AEPG” or “IS200AEPGG1A.” The physical connector and wire arrangement should also be matched before installation.
