Description

The DS3800NFCF is a printed circuit board manufactured by GE. It is a component in the Mark IV/Speedtronic series, which was designed for gas and steam turbine control. The Mark IV can be used to automate most procedures for turbine management, including startup, shutdown, and cooldown procedures. It can also keep the turbine system running within safe parameters.

The DS3800NFCF is designed as a firing circuit board. It has the following specifications:

• It is factory drilled in all four corners.

• It attaches to daughter board DS3800DFCF.This auxiliary board has three ammeters and five jumper switches. When installed, the auxiliary board is held in place by seventeen board-to-board pins located on the left side of the DS3800NFCF.

• It has two plunge switches. These are marked "step" and "rest." The switches are placed toward the bottom left corner of the board.

• It is built with fifteen LEDs, including fourteen red and one amber LED.

• It has one straight 10-pin vertical connector, and two connectors (located along the right edge of the board) labeled 218A4637-P4 0027.

• It has twenty-one transistors.

• It has twenty-nine test points.

• It is marked for identification, marked "66A07," and marked for alignment along the top edge.

• It has two jumper switches.

• It is built with forty-two integrated circuits, including circuits from Texas Instruments that function as Synchronous 4-bit up/down counters, and Dual J/K Negative-edge-triggered flip-flops.
