The DS3800NPID1F1F was designed for the Mark IV system which is a series of turbine operation and automation. This device is a printed circuit board. The DS3800NPID1F1F is what is known as a regulator module circuit board. The DS3800NPID1F1F was created by GE, or General Electric.
The DS3800NPID1F1F is a daughter board, which is a small board that may be attached to a larger circuit board. Adding a daughter board gives a circuit board extra functionality and provides more options for the operator. Most notable on the DS3800NPID1F1F is a large grey metal plate. This plate is attached perpendicular to the DS3800NPID1F1F. Featured on this plate adjacent to the surface of the circuit board are three (3) large silver transistors. A large silver diode is attached to the perpendicular part of the plate. This diode is attached to the DS3800NPID1F1F by grey wires. Also connected to this part of the metal plate is a large inductor, otherwise known as a coil. This inductor is also connected to the circuit board with wire. Two (2) large rectangular resistors which are grey in color are placed on the right edge of the DS3800NPID1F1F. Each of the resistors has a wattage of ten (10) watts. Thirty-seven (37) resistor networks are aligned along one of the edges of the DS3800NPID1F1F. These resistor networks are small and yellow in color. Each resistor network is numbered in white on the surface of the DS3800NPID1F1F. Two (2) small transistors are paired together near the side of the circuit board next to the resistor networks.
