Description

The DS3800NDID1P1A is a PCB from GE. This is a component in the Mark IV series, which is used for steam and gas turbine control. The DS3800NDID1P1A is a large printed circuit board with many components and two auxiliary boards. It has these specifications:

• It is built with seventy-six integrated circuits.Circuits include low offset low power voltage quad comparators (SM 9136 LM339N,) crystal oscillators (Gencom Mfr 01526,) 2-input positive OR gates (Texas Instruments SN74LS32N,) and two line to four line decoders/demultiplexers (Texas Instruments SN74LS155AN.)

• One auxiliary board is marked '6BA9407P2.' The other is not marked. The unmarked board is built with eleven chips including Motorola LS2790 X801 and Motorola LM 348 901.

• It is built with two potentiometers (one rotary and one trim) and two resistor networks.

• It has six jumper switches.

• There is a heat sink located in the upper left quadrant.

• It has twenty transistors, eighteen TP test points, and a row of spare PTH.

• One push button switch (marked 'rst,') is placed near three LED strips and seven LEDs.

• It has six connectors built into the board to communicate with other PCBs. This includes two 218A4553-1 connectors along the left edge, one small ribbon connector in the middle of the board, and three male connectors (one horizontal and two vertical.)

The DS3800NDID1P1A has been stiffened by two PCB board supports. It has been factory-drilled and alignment marked. Extractor clips are installed. The board also has seven vertical nylon spacers attached to the right and middle of the board. Resistors on the DS3800NDID1P1A tend to be made of metal film. Components have been labeled.
