Product Description
The DS3800NGMA1B1A is a PCB from GE designed as part of their Speedtronic/Mark IV system. This system, which was created for gas/steam turbine control management, keeps the system operating within safe parameters. It can also automate some procedures such as start-up and shutdown for better management control.
The DS3800NGMA1B1A has been built to accept the optional auxiliary board DS3800DGPA. When the auxiliary board is installed it gives the DS3800NGMA1B1A access to more components, including six trimpot potentiometers and several snap-in PCB screw mounts. If installed, the auxiliary is supported at each corner by nylon spacers already installed in the motherboard. It is held in place by two lines of metal pins, twenty-eight in all.
The DS3800NGMA1B1A is built with thirteen TP test points, one amber LED (labeled 'Imok,') one transistor, one female 28-pin Augat connector, five integrated circuits, and one male connector (218A4553-1 A/mp.) It has four rotary potentiometers and four jumper switches.
The DS3800NGMA1B1A is built with a PCB reinforcement bar installed along its top edge. This stiffens the board and limits how much it can flex. The board is alignment marked. It has been factory drilled in each corner. Extractor clips are installed in the right-hand corners. These clips help protect circuitry during installation and extraction by giving technicians a way to 'lever out' the board from tight locations. The board is populated with various resistors, diodes, and capacitors.
Manuals and datasheets for the DS3800NGMA1B1A were originally distributed by General Electric. Technical support publications like these are excellent resources for maintenance schedules, safety guidelines, and installation instructions.
