About the DS3800NFCF1D1C
The DS3800NFCF1D1C is a printed circuit board from GE that functions as a firing board within the Mark IV/Speedtronic system. The Mark IV, which was designed for steam or gas turbine control, helps keep the turbine system working within safe parameters. It can also automate procedures like start-up and cool down.
The DS3800NFCF1D1C has 42 integrated circuits including 8-bit static MOS RAM with +5 V power supply, up/down binary counters, and negative-edge-triggered flip-flops. It is built with two jumpers, twenty-one transistors, and fifteen LEDs that are set in two groups on the board: one group of seven red LEDs, and one group of seven red LEDs and one amber LED. The DS3800NFCF1D1C can accept the auxiliary board DS3800DFCF. When this is installed the motherboard has access to another five jumper switches plus three ammeters. The auxiliary location is on the left side of the board. It is locked in place with seventeen pin connectors.
The DS3800NFCF1D1C is drilled for mounting. It is alignment marked along one edge. It has twenty-nine TPs (test points.) The DS3800NFCF1D1C has two plunge switches located in its bottom left quadrant along with one 10-pin male connector. There are two other connectors on the opposite side of the board; these are both labeled 218A4637-P4 0027.
The DS3800NFCF1D1C is built with several 200V capacitors (8542 +/- 2 M/E 0022.) It has multiple resistors of differing values, typically made of ceramic covered metal film.
Installation guidelines for the DS3800NFCF1D1C may be found in data sheets and manuals referencing the Mark IV system or this module. Technical support publications were distributed by GE.
