IS200EXAMG1AAB GE EX2100 Exciter Attenuation Module
IS200EXAMG1AAB is a high-precision exciter attenuation board for GE EX2100 turbine control systems.
The EXAM module interfaces with field windings to manage low-frequency AC excitation signals.
It ensures accurate current and voltage feedback for the EGDM ground detection system.
Designed for simplex or triple modular redundant (TMR) setups, it supports both configurations seamlessly.
The board integrates into the High Voltage Interface (HVI) within the auxiliary cabinet.

Professional FAQ
How does EXAM integrate with EGDM modules?
The EXAM provides attenuated signals for the EGDM ground detection system to ensure safe operation.
Can a single EXAM module work in both simplex and TMR systems?
Yes, interconnection remains identical; one EXAM supports both configurations.
Why are jumper settings JP1 and JP2 important?
They select filter capacitance to adapt to PPT voltage variations above or below 750 V rms.
What is the typical installation mistake to avoid?
Incorrect 9-pin EPBP connections can disrupt feedback and excitation signal accuracy.
How should buyers verify compatibility?
Confirm EX2100E series cabinet compatibility and simplex/TMR requirements before purchase.
