About the DS3800NOCA1B1B

The DS3800NOCA1B1B is a printed circuit board from General Electric designed to function as an overcurrent overload board within its Mark IV series.  This series, which was designed to manage steam/gas turbine systems, increases efficiency by automating such procedures as cool down and shut down.  It can also be used to monitor air, fuel and water emissions.

The DS3800NOCA1B1B has twenty board-to-board pins attached in a single line parallel to its right edge; these are designed to connect to the optional auxiliary board DS3800DOCA. Several quick-connect screw mounts and four trim potentiometers become available to the motherboard when this auxiliary is attached.  The optional auxiliary is supported by four nylon pins.

The DS3800NOCA1B1B is built with five TP test points (labeled TP0 through TP4,) six light emitting diodes (LEDs,) and one each toggle switch and transistor.   The board is built with one female Augat connector (28-pin,) and one right-angled mating connector. The latter is located along the board’s left edge and is labeled 218A4553-1 AMP 102041-1.  

The DS3800NOCA1B1B has been factory drilled and is alignment marked, A through J.  It is built with two extractor clips. These clips are designed to make it easier to insert or extract the board from tight locations.  The clips can be used as a lever point or as a handle, as needed.

The DS3800NOCA1B1B is built with many circuits, including hex inverting gates that perform the logic INVERT function, quadruple 2-input positive-nand buffers with open-collector inputs, which are often used to generate high V(oh) levels, and dual operational amplifiers that offer short-circuit protection and have low power consumption.

Technical support for the DS3800NOCA1B1B came from General Electric.  This includes all publications like manuals and datasheets.
