DS3800HDDA1A1A

Product Description

The DS3800HDDA1A1A part number refers to a General Electric printed circuit board that functions as a Mark IV Speedtronic display driver board.  General Electric released a number of Speedtronic systems for the management of gas and steam turbines, starting with the MKI in the late 1960s.  These continued to develop and improve, with the Mark IV being the first of these systems to offer triple modular redundant control, which allowed hot-swap of many components. 

The DS3800HDDA1A1A  is a small printed circuit board with factory drill holes located in each corner of the board.  There are two drill holes in each corner.  These can be used to mount the board in its proper position.   The center of the board’s surface has several lines of integrated circuits, while the board’s edges are populated by right-angled connectors to allow the board to communicate with other parts of the Mark IV system.   Speedtronic systems before the Mark IV used screw-type connectors rather than plug-type connectors.  But the change over to plug type connectors allows for a faster switch out of board components.  

The Mark IV offers flexible and adaptable sequencing that is adequate for most end-user application changes.   These changes are possible due to the ladder-logic-based sequential turbine control that the Mark IV system uses. 

More details about the DS3800HDDA1A1A board component or about the Mark IV system, in general, can be sourced from GE manuals, datasheets, and user guides.   This documentation would have been offered along with your OEM purchase from General Electric.  AX Control may have resources that can help you if these publications are no longer available.
