About the DS3800NFCF1F1E
GE developed the DS3800NFCF1F1E as a turbine control firing circuit board for the Mark IV series. The Mark IV was designed for gas or steam turbine control and can keep those systems from operating in unsafe operating conditions. It can also automate some procedures, such as start up and cool down.
Hardware Tips and Specifications
The auxiliary board DS3800DFCF can be attached to DS3800NFCF1F1E by seventeen board-to-board connectors located on the left quadrant of the board. When this auxiliary board is in place it gives the DS3800NFCF1F1E access to more components, including ammeters and jumpers. Four nylon pins are in place to support the DS3800DFCF if it is installed. The DS3800NFCF1F1E has 42 circuits. This includes 8-bit static MOS RAM chips with an internal address latch and minimum access time of 400ns, 4-bit up/down counters with fully independent clear input which forces all outputs to the low level when a high level is applied, and dual J-K negative-edge-triggered flip-flops that are fully buffered to offer maximum isolation from external disturbance.
The DS3800NFCF1F1E has two jumper switches that allow for some customization. It has three connectors for communicating with other PCBs (one 10-pin male connector and two 218A4637-P4 connectors.) It has twenty-one transistors, fifteen LEDs, and twenty-nine TP test points located across the board. It is built with multiple diodes, capacitors, and resistors. The DS3800NFCF1F1E had installation guidelines published by GE in datasheets and manuals. These technical support publications are the best reference when maintaining this equipment. Only qualified electrical personnel should install or maintain Mark IV components.
