Product Description

The IS200EGDMH1AGG Exciter Ground Detection Module was manufactured by GE Industrial Systems, the General Electric shell company that handles the manufacturing of the entirety of the EX2100 Excitation Control Series. This EGDM-abbreviated product features three total significant product revisions; an A-rated functional revision, A G-rated functional revision, and finally a G-rated artwork revision. 

Hardware Tips and Specifications

In examining this IS200EGDMH1AGG Exciter Ground Detection Module, a handful of significant product hardware and performance specifications can be retrieved from originally-issued instructional manual materials concerning this product. For example, the original intended functionality of the IS200EGDMH1AGG board can be deduced to its detection of a ground path from any exciter component connected to or including main field wirings. This EGDM-abbreviated module is intended to be mounted in a control power supply module located in the greater control systems' control cabinet. Before making a purchase decision for this IS200EGDMH1AGG product, it is important to remember its dimensional status as a double height, double-slot form factor board. The number of EGDM boards present in their respective Ex2100 drive assemblies is indicative of the type of system they find themselves aligned with; triple modular redundant systems tend to offer three EDGM boards, while simplex systems make use of only only of these IS200EGDMH1AGG products.

While it is important to understand the role that the IS200EGDMH1AGG printed circuit board plays in its greater EX2100 Excitation Control Series, it is important too to recognize some of the hardware components affixed to its base circuit board; all important in contributing to its intended functionality. A primary highlightable hardware trait of this IS200EGDMH1AGG PCB can be identified in its Sense Resistor, which is central to its detection functions. This Sense Resistor can be more accurately classified as a simple unity gain differential amplifier with a high common-mode rejection ratio. This differential amplifier is followed by an A to D converter, which itself is attributed to be a Voltage Controlled Oscillator VCO. This A to D converter interfaces with the compatible EISB option board through the use of a fiber-optic style transmitter component. All of the hardware components mentioned above should be protected by a layer of conformal printed circuit board coating. Conformal PCB coating, unlike the alternative normal style of PCB coating, is a comprehensive layer of PCB coating that envelops every surface of every hardware component attached to the base board of this IS200EGDMH1AGG Exciter Ground Detection Module.

Frequently Asked Questions about IS200EGDMH1AGG

Does this IS200EGDMH1AGG Ground Detection Module make use of any SCOM grounding output terminals?

No. As indicated by this product's IS200 regular assembly version, the IS200EGDMH1AGG PCB does not incorporate any SCOM grounding output terminals in its assembly.

How is normal PCB coating different from conformal PCB coating?

Unlike conformal PCB coating, the normal style of PCB coating supplies its respective circuit boards with only a basic, non-comprehensive layer of printed circuit board protection that does not envelop every hardware component entirely.

How is a functional revision different from an artwork revision?

While Artwork PCB revisions handle the visual configuration or placement of components on the base circuit board, functional revsions add certain hardware components to increase the actual functionality of the product. This IS200EGDMH1AGG PCB has two functional revisions, and a singular artwork revision.

Reviews For IS200EGDMH1AGG

Internal Review

This IS200EGDMH1AGG EX2100 Ground Detection Module is a specialized EX2100 Excitation Control Series printed circuit board that should be robustly protected by its unique G-rated artwork revision and conformal style of printed circuit board coating. Before making a purchase decision for this IS200EGDMH1AGG model PCB, it is important to remember its status as a double-height EX2100 Excitation Control Series PCB, which may be added onto through its inclusion of three significant product revisions. - AX Control Lead Technician
