Product Description

This IS200EAUXH1AAA printed circuit board was manufactured by industry giant manufacturer General Electric, and was intended for use in their EX2100E series of excitation control systems and excitation control system component products. This part is considered a revised product, as it modifies the original  IS200EAUXH1 parent product through an introduction of its three, A-rated significant product revisions. While all of the revisions that significantly affect the  IS200EAUXH1AAA board are similarly rated at "A" grades; two of these are classified as functional revisions, while the third exists as an artwork revision, designed to encourage greater IS200EAUXH1AAA board durability or aesthetic quality. The IS200EAUXH1AAA printed circuit board can be more explicitly defined as a Exciter Auxiliary I/O Interface Board, considering its functional purpose.

Hardware Tips and Specifications

It is true that a number of relevant information surrounding this IS200EAUXH1AAA is relatively unavailable, considering its status as a legacy series product and the specificity of the board that comes with its three significant revisions. While this is true, much can be revealed about the IS200EAUXH1AAA PCB through a diligent visual inspection and part number breakdown. In visual inspection, one of the primary hardware elements noticeable affixed to the base board of this IS200EAUXH1A model is its series of jumpers; over eight in total along the outside of the EAUX board. These jumpers all come equipped with with standard factory-printed nomenclatures; J1-J8. Seven sizable relays are plugged into the base plate of this model, solidly increasing the overall thickness of the product to about four inches thick. This model PCB weighs about four pounds in total, and has SCR cell sizes of 42, 53, 77, and 100 mm each. Various insulated holes for installation purposes seem to have been drilled into the base board of the IS200EAUXH1A board in several positions.

While a visual inspection of the IS200EAUXH1A board can certainly yield some important hardware specifications, a lot of other information can be revealed through a diligent  IS200EAUXH1A part number breakdown. This EX2100e series board carries a typical series-functional product number, which begins with the IS200 tag designating the product as a domestically-manufactured General Electric offering. This initial IS200 tag has dual functionality, as it also identifies this EAUX-abbreviated model as an Exciter Auxilary I/O Board that does not make use of any special assembly version or SCOM grounding terminal. An instance of the EAUX functional acronym appears in the IS200EAUXH1AAA product number, before being quickly followed by the H1 series grouping tag; which classifies this product as a EX2100E excitation control series group one product that is protected by a layer of conformal-style PCB coating. The final trailing "A" digits present in this part number outline to the knowledgeable drive administrator this PCB product's three-fold revision history and revision grades. Before making a purchase of this specialized EX2100E series PCB, is is of course important to consider that any information present on this page is reminiscent of factory-printed instructional materials concerning the original unrevised IS200EAUXH1 parent product, and therefore may introduce slight inaccuracies.

Frequently Asked Questions about IS200EAUXH1AAA

What does this PCB's conformal style of PCB protective coating entail?

This IS200EAUXH1AAA board's conformal PCB coating is a thin layer of protective circuit board coating that should envelop every surface on every IS200EAUXH1AAA board hardware component, unlike the alternative normal PCB coating style.

Is this printed circuit board repairable through AX Control? 

Yes. As with the vast majority of our General Electric circuit board products, this IS200EAUXH1AAA PCB is available for both repair and replacement right here at AX Control, with a standard one to two week lead time on circuit board repairs.

What does this board's TMR acronym in its functional description describe?

This board's TMR status classifies it as an EX2100E Series PCB that utilizes a Triple Modular Redundant style of control system.
