Product Description
This IS200TREGH1AAA printed circuit board was originally designed by General Electric's subsidiary manufacturer GE Industrial Systems for use in their highly-specialized EX2100 Series of Excitation Control Systems and Excitation Control System component products. This PCB is a modified board, revised from its original IS200TREGH1 parent product through its installation of three seemingly-identical A-rated significant product revisions. While this IS200TREGH1AAA board seems to make use of three identical revisions, it is important to note that this TREG-abbreviated printed circuit board has two different significant revision types; two A-rated functional product revisions and a singular A-rated artwork configuration revision. This IS200TREGH1AAA printed circuit board is more exactly definable as its factory-specified functional description of a Trip Emergency Terminal Board.
Hardware Tips and Specifications
This IS200TREGH1AAA-model Trip Emergency Terminal Board's series of unique hardware component parts can perhaps be best understood contextualized within this TREG-abbreviated PCB's intended functionality. This terminal board is a crucial component to its greater VPRO Turbine Protection Module Assembly, controlling trip solenoids through its included relay voting circuits. This is done to ensure the VPRO module's intended functionality in providing emergency overspeed trip protections to turbine applications missing the crucial mechanical overspeed volt protection. The TREG Terminal Board controls the trip solenoid process by voting for three trip signals in their correspondent relay circuits and removing power from each individual trip solenoid.
Now that the intended function of this crucial Trip Emergency Terminal Board has been described, it is possible to explain some of its hardware inclusions. An immediately-observable hardware inclusion made by this TREG-abbreviated board is its important solenoid drivers, of which it has six in total. Other observable components present in the assembly of this IS200TREGH1AAA model PCB include its seven trip contact inputs and its series of two total emergency stops, which would be triggered by a diagnostic alarm code processed by this TREG board. This terminal board is considered compatible only with triple modular redundant control system styles, and was designed specifically for Gas Turbine processing applications. As indicated by this product's IS200 series tag, the IS200TREGH1AAA board was domestically-manufactured in General Electric's Salem, Virginia factory plant location, and features no sort of special assembly version beyond its three significant product revisions. Before making a purchase decision for this IS200TREGH1AAA model Trip Emergency Terminal Board, it is important to consider that any information included on this product page is reminiscent of the earlier, unrevised IS200TREGH1 parent circuit board, and that the actual performance specifications and hardware components exclusive to this IS200TREGH1AAA model may be altered through its three product revisions.
