Product Description
This IS205TFBHG1AAA General Electric printed circuit board was originally manufactured by GE Industrial Systems for use in their Innovation Series of turbine control systems and turbine control system component products. This IS205TFBHG1AAA printed circuit board or PCB for short is attributable as a General Electric product given its manufacturer GE Industrial System's subsidiary company status to the greater General Electric industrial giant retailer. While oftentimes referred to simply as a GE circuit board; this IS205TFBHG1AAA PCB is actually more specifically definable by its official functional description as a Temperature Feedback Board, as it appears in original, product-centric instructional manual materials. This IS205TFBHG1AAA Temperature Feedback board is a modified version of a different Innovation Series product offering; changing the IS205TFBHG1 parent printed circuit board through its inclusion of three significant, A-rated product revisions.
Hardware Tips and Specifications
This IS205TFBHG1AAA Temperature Feedback Board, unlike many similarly-labeled Innovation Series products, actually offers a good bit of original, product-specific manual information in online research. With this being true, it is not necessary to lean on any visual inspection or part number breakdown of this product. The intended functionality of the IS205TFBHG1AAA Temperature Feedback Board, as defined in these manuals, is to provide two total thermistor temperature feedback channels, which in turn are used for the monitoring of crucial IGBT cold plate temperatures. This board utilizes digital signal processing to enhance its inherent thermistor linearization application.
Now that some of the intended functionality of this IS205TFBHG1AAA Feedback Board has been explored, it is possible to seek contextualization of some of its interesting and unique hardware inclusions. As described in original instructional manual materials, this TFBH-abbreviated board makes use of 100 kilohm thermistors in two separate locations to encourage efficient IGBT cooling plate temperature monitoring. The voltages measured in this process are converted through the use of another specialized hardware component in this Feedback Board's assembly; an 8-bit, quad-channel analog to digital converter, or ADC for short. Other hardware components affixed to the baseboard of this TFBH-abbreviated model PCB include a standard number of voltage-regulating and voltage-limiting transistors, resistors, capacitors, and diodes.
More important information pertaining to this IS205TFBHG1AAA model Temperature Feedback Board is available upon a simple guided breakdown of its IS205TFBHG1AAA GE functional product number, which begins with the IS205 series tag. This series tag identifies the IS205TFBHG1AAA board as a special assembly-model printed circuit board manufactured in GE's Salem, Virginia factory plant. Other information gleanable from this device's functional IS205TFBHG1AAA product number include its TFBH functional acronym, its normal PCB protective coating style, its group one Innovation Series grouping, and its three significant product revisions, in this instance all rated at A grades.
