The DS3800HSPC1D1C was made as a speed position input board. It was manufactured by GE and a component of the gas and steam turbine control system known as Speedtronic Mark IV.
Very small components like capacitors, diodes and resistors are located on all 25 integrated circuits on the DS3800HSPC1D1C. Differing colors of capacitors are all over the board. A large number of the capacitors are black or light blue in color. One of the capacitors is yellow and 3 of them are silver. A single capacitor is covered in bands with different colors. Represented by the colored bands is the component’s energy capacity. Several resistors are also banded in various colors. The capacity of the device is represented by the bands on the resistors as well. The DS3800HSPC1D1C contains two transistors. The first transistor called Q1 is shaped like a half-circle and is black. Opposite to Q1 is the other transistors known as Q2 which is round and silver. DS3800HSPC1D1C has many diodes which are banded in shades of red. Allowing the board to be tested that it is working properly is a series of test points bordering the right end of the board. A blue connector port is on the right of the board. DS3800HSPC1D1C has a few jumper pins which can be connected by a black jumper. A potentiometer is on the right of the DS3800HSPC1D1C. A potentiometer is alternately called a variable resistor. This potentiometer is colored blue. A circuit board potentiometer like the one on the DS3800HSPC1D1C is used to change the variable resistor's resistance. Potentiometers are also used to control things like volume in other devices.
