About the DS3800NFDB1A1A

The DS3800NFDB1A1A is a small circuit board. This product is a part of the Speedtronic Mark IV series which is in charge of controlling both gas and steam turbines. The DS3800NFDB1A1A was manufactured by General Electric (GE). This part is a daughter board, which can be connected to a bigger board in order to provide additional components or extra functionality to that board.

Located in the center of the DS3800NFDB1A1A is a large silicon controlled rectifier. This device is also known as a semiconductor-controlled rectifier. It is labeled with the initials SCR as SCR1. A silicon controlled rectifier is a current controlling device which conducts current in only one direction. Also prominent on the DS3800NFDB1A1A is a large black resistor. The part number of the resistor, CTG-319-CGN33 is written on the top of the resistor. This resistor is labeled with the initial R and is called R2. Immediately next to this large resistor are two small diodes. These diodes are colored black and grey. They are labeled with the initials CR and are called CR1 and CR2. Situated on one end of the DS3800NFDB1A1A is a large silver capacitor. This capacitor is labeled with the initial C and is called C1. Located along one of the edges of this small card are three medium-sized resistors. These resistors are brown and banded in different colors. These bands are orange, white, black, and gold. The resistors are labeled with the initial R and are called R3, R4, and R5. Two small light blue resistors are placed on the DS3800NFDB1A1A. These resistors have multicolored bands and are labeled with the initial R, as R1 and R6.
