About the DS3800HMPJ1A1D
The DS3800HMPJ1A1D is a General Electric Mark IV circuit board. This board fits within the MKIV turbine control system Series designed to manage industrial gas and steam turbines of various sizes and complexity, as you have more than likely been able to guess based off of its full extended series name alone. The Mark IV was the first of the Speedtronic systems to increase reliability by using a TMR (triple modular redundant) arrangement. This use of duplicated processors voting on all inputs allowed for less downtime within the overall system. The Mark IV Turbine Control System Series' intended functional applications unfortunately had not yet been expanded to include the alternative energy-based wind turbine control and management settings seen in later-released General Electric Mark product series such as the Mark VI Turbine Control System Series. This DS3800HMPJ1A1D device's greater Mark IV Turbine Control System Series must be considered obsolete as a whole series, as it is one of the final-developed GE Mark product series taking advantage of the Speedtronic control system technology first seen with the rollout of the primary Mark I Series in the mid to later 1960s.
Hardware Tips and Specifications
Designed with a backplane connector on one short edge and a cable connector on the other, the DS3800HMPJ1A1D is just one version of this board available within our warehouse stock. The DS3800HMPJ1A1D board is marked with its ID number as well as several codes to aid with the position, wiring, and other board specifications. Codes may vary according to the individual unit sold. The DS3800HMPJ1A1D is built with a vertical pin connector. This is near four standoffs mounted to the board surface, allowing the addition of a secondary daughterboard that will communicate with the DS3800HMPJ1A1D through the cable connector. The board has over fifty integrated circuits including multiple PROMs/EPROMs. Other board components include LED indicators (one yellow, one red), resistor network arrays, resistors, diodes, capacitors, test points, and jumper switches. Jumpers are used to change settings on the board; this allows the board to be customized as the end-user requires. GE documentation will give more information on jumper settings. However, jumpers on your replacement board should typically match those of the board you are replacing. Most orders for in-stock products will ship from our warehouse on the same day they are received. It cannot be confirmed whether or not this DS3800HMPJ1A1D product is the original device of its specific Mark IV Series functional role.
While this DS3800HMPJ1A1D printed circuit board product offering has not been adorned with the typical metal installation faceplate of Mark IV Series products, the two retention clips made available to the very right-hand side of this DS3800HMPJ1A1D product make it obvious that this DS3800HMPJ1A1D PCB here has been specifically primed for insertion in the Mark IV Series's standard VME Rack Installation Assembly. Several additional factory-drilled installation holes have been made in the base circuit board of this DS3800HMPJ1A1D Microprocessor Board here as well through; with each of these holes being ringed with an insulated material in order to avoid potentially-damaging surface voltages or static electricity damage. Given the fact that this DS3800HMPJ1A1D circuit board featured here is a member of a now-obsolete legacy General Electric product series, it is not all too surprising to discover that it is not surrounded online by any large quantity of originally-printed instructional manual materials. With this being the case, the DS3800HMPJ1A1D functional product number itself becomes a decent supplementary source of DS3800HMPJ1A1D Board hardware component and component specification information, as it codes for these details through a series of consecutive functional naming chunks. For instance, the initial dual-functional DS3800 series tag chunk describes both this DS3800HMPJ1A1D PCB's domestic original manufacture location as well as its group one Mark IV Series product grouping. Some of the other relevant hardware details embedded in functional segments of the DS3800HMPJ1A1D functional product number include this HMPJ-abbreviated device's:
