About the IS200ESYSH2AAA
Originally manufactured by the General Electric shell company GE Industrial Systems, this IS200ESYSH2AAA PCB or printed circuit board is a modified version of the original IS200ESYSH2 parent PCB, and features three significant product revisions, all rated at "A" grades. This EX2100E Excitation Control Series printed circuit board is more explicitly definable through its functional description as a Triple Modular Redundant EX2100E System Input/Output Board.
Hardware Tips and Specifications
To understand the IS200ESYSH2AAA product is to first understand all of its intended functionality within the greater EX2100E Excitation Control Series. This ESYS-abbreviated printed circuit board acts as a signal conditioner for generator currents and voltages produced by the greater EX2100E Series Drive Assembly's PTs and CTs. These control signals are needed by important assembly functions such as automatic regulator, limiter and protection functions. Beyond the very limited functions outlined here, not a ton of pertinent information surrounding the IS200ESYSH2AAA TMR system I/O Board is available through analysis of its original instructional manual materials. With this in mind, the remainder of the product-specific information sourced below has been derived from a thorough breakdown of the IS200ESYSH2AAA unique produce number.
In examining the IS200ESYSH2AAA functional product number, the first obvious element can be described as the IS200 series tag, which has dual naming functionality for this printed circuit board. This IS200 series tag is indicative both of this product's normal assembly version, and of this circuit boards' domestic manufacture location, of Salem, Virginia specifically. This IS200 series tag is shrugged in the IS200ESYSH2AAA part number for its ESYS functional acronym; created with the intention of existing as a convenient functional shorthand for the full IS200ESYSH2AAA product number. This ESYS functional acronym is followed by the H2 series grouping tag in the IS200ESYSH2AAA product number, which, similarly to previously-mentioned IS200 series tag, has dual naming conventions for this product. This H2 series grouping tag defines the ESYS board as a board with EX2100E Series Group 2 series grouping, and as a PCB that makes use of the exhaustive, conformal style of printed circuit board protective coating. The final three "A" digits in the IS200ESYSH2AAA part number reveals this product's three-fold revision history.
