The DS3800NSCD1B1C, manufactured by GE, is a PCB designed to act as a Speed/current card for the Mark IV system. This system was designed for steam/gas turbine management.
The DS3800NSCD1B1C is built with ten potentiometers along the right edge. These are all rotary potentiometers, which can be individually set for voltage division. Each has been labeled. Their labels are as follows: Spd Fdbk, Spd Gain, Ref, Rev CL, Fwd CL, Curr Gain, CL Bias, CL Slope, Aux 1, and Aux 2. The board also has one test point, which is located at the end of this line of potentiometers. The test point is labeled “tst.”
The DS3800NSCD1B1C has one mating connector for communicating with other PCBs. This connector is on the left edge. The connector is marked 218A4553-1Amp 102041-1. The board is numbered behind this connector by tens from ten to eighty.
The DS3800NSCD1B1C does not have many through-hole components. The connector and potentiometers mentioned are through-hole components. There are also two capacitors on the board that are through-hole components. These are located at C18 and C19; both are polyester vinyl and are rated at 200V. There are nineteen through-hole resistors on the board. The rest of the components on the DS3800NSCD1B1C are connected via twenty-eight pairs of quick-connect screw mounts located across the board.
The DS3800NSCD1B1C is factory drilled and alignment marked. It has clips for extraction added to each right corner. Extractor clips benefit the technician during installation or extraction, as they give the worker a lever point or a handle to move the board with, thus protecting components and circuitry from rough handling
