Product Type Exciter attenuating module
Model IS200EXAMG1B
The excitation attenuator module IS200EXAMG1B is widely used in the EX2100 series. The board is mounted in an auxiliary cabinet and is typically used to present the low-frequency signal from the exciter field grounding detector module, which is then sent to the detection resistor in the EXAM module. This process will provide a current voltage at both ends of the resistor and then send it back to the field ground detector.
There are two obvious differences between the IS200EXAMG1A and IS200EXAMG1B systems. The Alterrex application will require the use of two IS200EXAMG1B models and two simplex ground detectors that support EROC. The redundant system used with this model will generate test signals from the M2 or M1 controllers, which are used in conjunction with the C controllers, which control the switches used to switch between the two M controls.

There are several manuals that can be used with the IS200EXAMG1B module. These manuals are GEI-100467 and GEH-6632. GEI-100467 is a product-specific manual. The GEH-6632 manual contains information about other modules used with EXAM and the different dirhams that show modules in the auxiliary cabinet.
General Electric Company IS200EXAMG1B exciter attenuation modules are manufactured as part of the EX2100 and EX2100e exciter Control 35A and 120A regulator systems. The IS200EXAMG1B module is designed to be installed in the auxiliary control cabinet and apply the low frequency signal from EGDM to the resistor.
IS200EXAMG1B exciter attenuation module is a device used to adjust the excitation current, usually composed of resistors and rheostat, used to reduce the excitation current, so as to adjust the output voltage of the generator. The module is usually controlled by the excitation controller, which automatically adjusts the excitation current according to the actual need.
Common excitation current regulating elements are resistor, rheostat, reactor and so on.
