About the DS3800HFPG1D1G
DS3800HFPG1D1G Drive Control Board
The DS3800HFPG1D1G is a Mark IV board component manufactured by General Electric. The Mark IV significantly reduced downtime caused by parts failure as compared to its predecessor, the Mark II. It did this through its control architecture that features triple modular redundant voting on all protection parameters and critical controls. This type of control allows the system to enlist “two out of three voting” to bypass discrete faults and keep the overall system running. Mark IV boards are no longer actively manufactured, but they can be purchased from AX Control as reconditioned and fully tested units.
The DS3800HFPG1D1G is a Drive Control Board. This is a large circuit board with many board components. The board has two backplane connectors on its leading edge. The opposite long edge is fitted with two extractor clips and one right-angled cable connector. The center of the board also includes a single vertical pin cable connector (male.) The board is fitted with several standoffs to allow the mounting of an auxiliary board. There are two board stiffeners installed along the long dimension of the board, one along the centerline and one along the bottom edge just behind the backplane connectors.
Other board components that appear on the DS3800HFPG1D1G include twelve jumper switches, five resistor network arrays, a single amber LED indicator and a bank of red LED indicators, board-to-board pin connectors, TP test points, spare PTH, capacitors, diodes, and resistors. The board has over eighty integrated circuits; most of these ICs are marked on their top surface with their original manufacturing codes that will allow the user to look up additional information about each chip if desired. For more information about the board, including handling and installation procedures, refer to GE manuals and data sheets.
