Product Description

This IS220PTURH1AC model printed circuit board was originally manufactured by GE Energy; the General Electric subsidiary manufacturer in charge of the mass production of all of the respected industry giant's alternative energy-geared products. The location of this printed circuit board or PCB's original manufacture is almost certainly GE Energy's Salem, Virginia factory plant. This IS220PTURH1AC PCB is actually a modified version of the original IS220PTURH1 parent board; featuring two significant revisions rated at "A" and "C" respectively. This PCB is actually more explicitly definable by it functional description as a Primary Turbine I/O Pack.

Hardware Tips and Specifications

While attributable as a Primary Turbine I/O Pack, not a whole lot of other original factory-distributed documentation surrounding the IS220PTURH1AC module specifically exists online. With this being true, it is difficult to understand the exact specific intended functionality of this product, beyond its basic functional description as a Turbine I/O Pack. It has been theorized that this is a Primary style of turbine I/O pack due to similar naming conventions in other related GE Energy Mark VIe Series products.

 While the intended functionality of this product is somewhat unknown, existing instructional documentation surrounding this PCB detail some important specifications. For example, the compatibilities of various terminal boards including the TTURH#C, STURH#A, and TRPAH#A terminal boards within the greater Mark VIe system assembly are explored. The IS220PTURH1AC I/O Pack or I/O Packs are used in conjunction with these specific terminal boards for 48-point Turbine Specific Primary Trip applications, or additional 480-point Aeroderivative Turbine Primary Trip applications (when used with the TRPA board).

As this is about the extent of original factory-issued instructional material available online concerning this IS220PTURH1AC Primary I/O Trip Pack, it remains important to consider the different functional pieces present in the IS220PTURH1AC product number. This IS220PTURH1AC product number begins with the IS220 series tag which outlines this product's special assembly version, before referencing the PTUR functional acronym. This acronym exists as a convenient conversational or promotional shorthand for the lengthy IS220PTURH1AC product number, and is itself followed in the IS220PTURH1AC number by the dually-functional H1 series grouping tag. This series grouping tag designates the IS220PTURH1AC board as a Mark CIe Series Group One member that is protected by the conformal style of printed circuit board protection. Conformal PCB coating, unlike the alternative Normal PCB coating, is a thin, chemically-applied layer of PCB protective coating that should exhaustively coat every surface of every hardware component affixed to the baseboard of this IS220PTURH1AC board. The final two alphanumeric "AC" digits in this board's unique product number seek to describe this PCB's two differently-rated functional revisions, which may alter this PCB's performance and hardware specifications slightly from those included on this unrevised parent product-based page.
