PRODUCT INFORMATION
Product Overview
The General Electric IS200EXHSG4A is an Exciter High Speed Board designed for Mark VI and Mark VIe systems. This board functions as a static exciter high-speed relay driver terminal board. It represents the fourth and final revision within the EXHS model series. The assembly integrates solid-state relay driver circuitry instead of forty-one direct-current contactors found on EXTB terminal boards. Two onboard conduction sensors are designated as E1 and E2 for monitoring operational excitation states.
The circuit board incorporates seven built-in relays along with three vertical male ribbon connectors. Transistors, resistors, capacitors, and integrated circuits manage signal distribution across the assembly. Specific component locations remain unpopulated because earlier revisions required components that this G4A revision does not need. The assembly weighs approximately two pounds and was manufactured in the United States. Control system documentation refers to the functional acronym EXHS in installation drawings.

PRODUCT FAQ
Frequently Asked Questions
What is the primary function of the IS200EXHSG4A board?
It serves as a static exciter high-speed relay driver terminal board in Mark VI and Mark VIe systems.
How does the IS200EXHSG4A differ from the standard EXTB terminal board?
It utilizes solid-state relay driver circuitry rather than the forty-one DC contactors installed on the EXTB.
Why are some component footprints unpopulated on the IS200EXHSG4A?
Earlier EXHS revisions required those components, but the G4A revision design does not require them.
What manual outlines the operation of the IS200EXHSG4A?
Manufacturer manual GEH-6632 covers detailed technical documentation for this exciter board series.
