Product Description

The IS200EXAMG1B (IS200EXAM) Exciter Attenuation Module is used in EX2100 and EX2100e Excitation Control System made by GE Industrial Solutions. This board conveniently mounts in the system's auxiliary cabinet and renders lower frequency signal that originates from the Exciter Field Ground Detector Module to the sense resistor. This process provides a current voltage across the resistor then dispatching it back to the Field Ground Detector. There are 2 relevant differences with certain systems as outlined below:

- Alterrex applications can use Qty 2 IS200EXAMG1B along with Qty 2 EROC enabling 2 simplex ground detectors

- Redundant systems can result in a test signal originating from M1 or M2

There are a number of GE Instruction Manuals and Publications that reference the IS200EXAMG1B depending on it's use and the system in which it is installed. These include GEI-100467, GEI-6632, GEI-6632G, and GEI-100509. GEI-6632 specifically provides diagrams showing the IS200EXAMG1B position in the auxiliary cabinet.
