DS3800NFCD1S1J

Product Description

GE developed the DS3800NFCD1S1J to function as a firing circuit board within the Mark IV Speedtronic system. The Mark IV, which was designed for steam and gas turbine control, uses integrated chipsets built with intentional redundancies in order to maximize efficiency and minimize downtime.

The DS3800NFCD1S1J acts as a motherboard for the smaller auxiliary DS3800DFCD. When this board is attached, the DS3800NFCD1S1J has access to the daughter board's four jumper switches and three ammeters. The auxiliary is placed along the left edge of the DS3800NFCD1S1J and is supported by four nylon pins. It is held in place by seventeen brass nickel plated pins.

The DS3800NFCD1S1J has the following specifications:

• -factory drilled, all corners. The board has two holes drilled in each left corner.

• -alignment-marked (A-L.)

• -five connectors on the board. These include two connectors on the right edge (218A4637-P4 11492BR&32694AR,) one male 5-pin vertical connector, and two Augat DIP plugs.

• -fifteen LEDs (fourteen red, one amber.)

• -two plunge switches.

• -over twenty transistors.

• -thirty test points.

• -44 integrated circuits. These include Intel's D8243 L50239830 MCS-48 Input/Output Expander, Motorola's SN74LS74AN XA89605 Dual D-type positive-edge-triggered flip flops, and Motorola's SN74LS112AN Dual J-K flip flops.

• -four jumper switches.

• -various capacitors and diodes. The board is built with many ceramic covered metal film resistors of differing values.

If the user finds that installation guidelines or maintenance schedules for the DS3800NFCD1S1J are required, these may be found within technical support publications referencing this part such as manuals or data sheets that were distributed by the original manufacturer.
