About the IS200EXHSG3AEC

The IS200EXHSG3AEC is a printed circuit board (PCB) component manufactured by GE Industrial Systems as part of the EX2100 Excitation Control series. The EX2100 is among General Electric’s most popular turbine management systems, featuring a Triple Modular Redundant (TMR) design. It produces the field excitation current necessary to regulate AC terminal voltage and reactive volt-amperes.

The EX2100 series is a full static excitation control system developed for generators on new and retrofit steam turbines, as well as gas and hydro turbine generators. The IS200EXHSG3AEC functions as a Static Exciter High-Speed Relay Driver board within the EX2100 system.

This product is part of the broader Mark VI Turbine Control System Series, which is highly sought after for purchase and repair due to its status as one of the last-developed GE Mark series to incorporate the patented Speedtronic control system technology.

Hardware Tips and Specifications

• The IS200EXHSG3AEC includes a solid-state relay driver and is typically paired with a high-speed contactor.

• Key components on the board include:

• Heat sink

• Seven relays

• Integrated circuits

• Transistors

• Capacitors (over fifty for energy storage)

• Metal film and carbon composite resistors (over one hundred)

• The board features three D-shell vertical pin connectors and eight plug connectors of various sizes.

• Several wire jumpers are factory-installed for initial voltage testing; these are not customizable.

• The PCB edges are drilled and ringed with conductive material for mounting.

• Two corners of the board are clipped, and four small notches are cut into the front edge for installation purposes.

• Large relays are labeled using industry-standard “K” nomenclature, such as K53B_C and K53A_M1.

• The entire hardware is protected by a thick layer of normal PCB coating, providing solid protection though not as comprehensive as conformal coating.

For detailed installation and functionality guidance, please consult GE Industrial Systems manuals or user guides that accompany the product. Warnings and handling instructions should be reviewed prior to installation.
