Product Description

This IS200EXAMG1AAB printed circuit board was originally designed by General Electric shell company GE Industrial Systems; intended for use in their EX2100 Series of Excitation Control Systems and Control System Option Boards. This is a modified version of the original parent IS200EXAMG1 board, and comes revised through three significant product revisions. This IS200EXAMG1AAB printed circuit board can be more accurately described as an Exciter Attentuation Module, as seen in its original, product-specific instructional manual materials.

Hardware Tips and Specifications

The IS200EXAMG1AAB Exciter Attenuation Module's important, specific hardware specifications are best understood when contextualized alongside its intended function within the greater EX2100E Series Drive Assembly. This EXAM module, as it is oftentimes abbreviated as, drives the electrical center of its field winding with a ac voltage that is categorized as lower-frequency, at least relative to the ground. Current flow detection for this process is detected through the use of a sensing resistor which is picked up by this EXAM module and measured by the corresponding EGDM module. This signal is sent to the correct EX2100E Series controller for monitoring and alarming through the use of a singular fiber-optic link. Considering the limited status of original factory-issued instructional materials concerning the IS200EXAMG1AAB board specifically, the rest off the information posited on this IS200EXAMG1AAB product page below has been sourced from a thorough breakdown of the individualized IS200EXAMG1AAB product number.

A primary recognizable component of the IS200EXAMG1AAB product number can be defined as its IS200 series definition tag, which actually holds dual naming responsibilities for this IS200EXAMG1AAB printed circuit board. This IS200 series tag identifies the IS200EXAMG1AAB Exciter Attenuation Module as a domestically-manufactured General Electric product with no special assembly version. This board's location of the original manufacturer can be more specifically attributed to General Electrics' Salem, Virginia factory plant location, where all IS200-rated boards come from. The IS200EXAMG1AAB product number's IS200 series tag is followed by an instance of the EXAM functional acronym, which exists as a convenient conversational promotion shorthand of the lengthy IS200EXAMG1AAB product number. This EXAM acronym is followed by the G1 series grouping tag, which designates this IS200EXAMG1AAB Exciter Attenuation Module as a EX2100E Series Group One product that is protected by a layer of normal printed circuit board protective coating. The final "AAB" digits present at the end of its product number describe this printed circuit board's three-fold revision history.

Frequently Asked Questions about IS200EXAMG1AAB

How would I know if this IS200EXAMG1AAB PCB has a special assembly version?

If this EX2100 Series PCB was to feature the "IS210" or "IS215" series tag, then its status as a special-assembly model would be revealed.

Why is the EXAM functional acronym considered functional?

The IS200EXAMG1AAB PCB's EXAM acronym is a functional acronym as it is a shortened acronym representing this product's function as an EXciter Attenuation Module.

How is the IS200EXAMG1AAB's artwork revision different from its two functional revisions?

While obviously differently-rated at a B grade, this product's artwork revision differentiates itself from its other two functional revisions as it has a different focus entirely; choosing to deal with the configuration of hardware components on this PCB's base circuit board.

Reviews For IS200EXAMG1AAB

Internal Review

A thrice-revised version of the original IS200EXAMG1 parent board; this Exciter Attenuation Module from GE's EX2100 series is meant specifically for excitation control system applications, and monitors and controls important diagnostics for the greater EX2100 series drive assembly through the use of a singular fiber-optic link. As such, it is crucial to double-check the functionality of this connector for the greater functionality of the IS200EXAMG1AAB Exciter Attenuation Module. This link's connection to the EXAM PCB's base board should be somewhat solidified through this model's thick, normal style of PCB protective coating. - AX Control Lead Technician
