About the DS3800NFCD1S1L
The DS3800NFCD1S1L is a printed circuit board manufactured by GE for the Mark IV system. The Mark IV was developed for gas and steam turbine management. It can protect turbine systems and keep them from running outside of safe parameters, and can also automate startup, cooldown, and shutdown procedures.
The DS3800NFCD1S1L is a larger PCB that performs as a motherboard for the smaller DS3800DFCD. This optional auxiliary board has four jumper switches (one of which is multi-positional,) and three ammeters. When attached, this gives DS3800NFCD1S1L extra components to access. Please see our separate listing for this board on our site.
The DS3800NFCD1S1L has 44 integrated circuits. This includes an input/output expander by Intel(8243) with four 4-bit I/O ports which serve as an extension of the on-chip I/O, as well as dual d-type positive edge-triggered flip-flops that utilize Schottky TTL circuitry (SN74LS74AN,) and dual J-K flip-flops from Motorola(SN74LS112AN, which feature individual J, K, clock and asynchronous set and clear inputs to each flip-flop.
The DS3800NFCD1S1L has two DIP plugs (Augat,) one vertical connector (5-pin male,) and two 218A4537-P4 connectors. These last are placed on the right board edge. The PCB is populated with two plunge switches, over twenty transistors, and thirty test points. It is marked for alignment along the top edge.
The DS3800NFCD1S1L has fifteen LEDs, with seven red LEDs positioned in the upper left quadrant and one amber LED, and seven red LEDs positioned in the lower left quadrant. There are multiple diodes, capacitors, and resistors placed over the board. Resistors tend to be ceramic-covered metal film and are of differing values.
If the user needs guidance installing the DS3800NFCD1S1L, the best source for this information is technical support publications such as manuals or data sheets. These were originally distributed by GE.
