IS200EXAMG1B GE EX2100 Exciter Attenuation Module

Description:

Exciter Attenuator module IS200EXAMG1B is used extensively in the EX2100 series. This board is mounted within the auxiliary cabinet and will typically be used to render low-frequency signals that are emitted from the exciter field ground detector module, the signals will then be sent to the sense resistor of the EXAM module. This process will provide current voltages across the resistors which are then dispatched back to the field ground detector. 

There are two distinct differences between the IS200EXAMG1A and IS200EXAMG1B systems. Alterrex applications will need to use two IS200EXAMG1B models along with two EROC-enabled simplex ground detectors. The redundant systems used with this model will result in a test signal originating from the M2 or M1 controllers, these are used with the C controller which controls the switch that is used to flip between the two M controls. 

There are several manuals that can be used with the IS200EXAMG1B module, these manuals are GEI-100467 and the GEH-6632, the GEI-100467 is a product-specific manual, and the GEH-6632 manual has information on other modules that the EXAM is used with as well as different dirhams which shows the module in the auxiliary cabinet.
