Product Description
The DS200DMCAG1A is a rectangular circuit board component fabricated by General Electric for use within their Speedtronic line of steam and gas turbine control. This is most often used within the Mark IV system, which was the first of the Speedtronic systems to be built upon a TMR, or triple modular redundant, design. This type of design, where all critical controls and protection parameters have secondary and tertiary backups, significantly reduces system downtime caused by equipment failure. The DS200DMCAG1A can be purchased from AX Control as a reconditioned used unit and as an unused new-used unit from liquidated stock. This DS200DMCAG1A printed circuit board is better-definable as a GEN/LOG/KEY Interface Board; its original instructional manual-included functional product description. While this DS200DMCAG1A PCB is definable as a Gen/Log/Key Interface Board in its own right, the originally-developed product of this functionality to feature within the Mark V Series is the DS200DMCAG1 Gen/Log/Key Interface Board missing this DS200DMCAG1A device's A-rated functional product revision.
Hardware Tips and Specifications
The DS200DMCAG1A functions as an Interface board, and because of this specific Mark V Turbine Control System Series functionality; necessitates its own series of specific hardware component inclusions and specifications. This board has several connectors on its surface. These connectors include three vertical pin header connectors, four vertical pin male cable connectors, and one female cable connector. Several stab-on connectors are also used. The board is populated by multiple other components including a reset switch, two fuses, seventeen resistor network arrays, four LED banks with a varying number of LED lights per bank, fifteen resistor network arrays, a small auxiliary board with several integrated circuits, and two heat sinks. There are over fifty integrated circuits located on the board’s surface, as well as various resistors, six high voltage electrolytic capacitors, smaller ceramic and polyester vinyl capacitors, diodes, an inductor coil, and transistors. A more detailed description of the board, its setup, and how to properly install it can be found within technical support publications from General Electric like user guides and manuals. Additional technical support products were supplied by GE with OEM purchases.
Given this DS200DMCAG1A printed circuit board's status as a member of a General Electric now-obsolete legacy product series, not a whole lot of its original instructional manual materials are available online for research purposes. With this being true, the DS200DMCAG1A functional product number itself can be considered a good source of DS200DMCAG1A board hardware component and specification information, beginning with its dual-functional DS200 series tag at the very beginning. The DS200 series tag at the beginning of the DS200DMCAG1A functional product number asserts this DS200DMCAG1A PCB's status as a domestically-manufactured product with a normal style of Mark V Series assembly. This tag is followed in the DS200DMCAG1A functional product number by an instance of the DMCA functional abbreviation which was created to exist as a functional shorthand alternative to the lengthy DS200DMCAG1A product number. This functional abbreviation is followed by another dual-functional naming component in the DS200DMCAG1A functional product number; the G1 series grouping tag revealing the DS200DMCAG1A PCB's normal style of PCB coating and Group 1 Mark V Series product grouping. The final A digit in the DS200DMCAG1A alphanumeric product number is a testament to the A-rated functional product revision altering this DS200DMCAG1A offering's normal Mark V Series assembly.
