The DS3800NCIA1B1C was manufactured by General Electric. It is a current isolator circuit board which was made to be part of the Speedtronic Mark IV turbine control series. A current isolator is necessary for proper functionality and safety of turbine systems. Using a current isolator gets rid of conducted noise, minimizes the possibility of ground loop, and keeps apart separate parts of a system. A current isolator is also very important for safety. An isolator enables accurate and safe measurements, protects users from faulty equipment, and protects circuits as well as equipment, but most importantly people, from electrical shocks or short circuit.
On the left border of the card, the DS3800NCIA1B1C has a connector port. There are 7 blue capacitors located toward the middle of the board. There are several yellow capacitors on the DS3800NCIA1B1C. Some of these capacitors are mid-sized and some of them are smaller. Also seen on the DS3800NCIA1B1C are 4 blue variable resistors, or potentiometers. The dials on the potentiometers give the user the option to change the resistance of every variable resistor. Two large transformers are on the left of the board and have the part name 218A4583P1 2 written on the top. Six transistors can be found in different places on the DS3800NCIA1B1C. Eleven integrated circuits are featured on the DS3800NCIA1B1C. Each integrated circuit, identifiable by the letter U, contains a range of tiny components such as diodes, capacitors, and resistors. Many resistors are located around the board which are covered in colored bands. These bands symbolize the resistance capacity of each resistor.
