Product Description
This IS200FOSBH1AAA printed circuit board was originally manufactured by GE Energy, the alternative energy-focused subsidiary company of industry-dominating giant General Electric. This printed circuit board can be more specifically defined by its functional description of a Fiber Optic Input/Output Board, and exists as a modified version of the original parent IS200FOSBH1 board. This PCB has three total significant product revisions; two functional revision and a singular artwork revision, all graded at "A" ratings.
Hardware Tips and Specifications
In order to make sense of the various differing hardware components offered to the IS200FOSBH1AAA printed circuit board purchaser, the prospective buyer must first seek to understand the whole functionality of this product, specifically. This Fiber Optic Input/Output Board has crucial interfacing capabilities in terms of other relevant Mark VIe Turbine Control System Series boards; the IS200FOSBH1AAA PCB acts as an interface for any signal received from the compatible IS200BICH Bridge Interface and Control Board (BICH), and this BICH-abbreviated boards' daughterboard, the BPIH-abbreviated bridge personality board. In total, this Fiber Optic I/O board interfaces for 24 total BICH board gate driver signals, which it multiplexes on a per phase basis. This IS200FOSBH1AAA board is additionally responsible for the issuing of two-stage soft shutdown sequences when the Mark VIe assembly experiences diagnostic trips or functional faults.
Now that some of the intended functionality and performance specifications of this IS200FOSBH1AAA printed circuit board have been identified, we may embark on our explanation of this FOSB board's hardware components. A primarily important hardware specification for this board is that is does not feature any sort of customizable hardware or manually movable jumpers in its overall configuration. While this is true, the IS200FOSBH1AAA Fiber Optic Input/Output board has two test points for diagnostic testing purposes, which should pair well with their factory-specified nomenclature labelings of DCOM and P5 for testpoints one and two respectively. The IS200FOSBH1AAA board's first testpoint is a Digital Common testpoint, whereas its second tespoint exists as a Positive 5 V dc Control Power testpoint. Beyond this device's testpoints alone exist other crucial hardware components, including Phase A, B, and C fiber optic connectors, as well as six plug connectors and two stab-on connectors. All of the aforementioned hardware components unique to this IS200FOSBH1AAA Fiber Optic Input/Output Board should be protected beneath a layer of conformal-style printed circuit board coating that envelops every surface of every hardware component affixed to the IS200FOSBH1AAA PCB's base board.
