General Electric (GE) created the DS3800NPSJ1B1B for the MKIV (Mark IV) turbine control system. This device is a printed circuit board (PCB). Mark IV is one system in the Mark series for turbine management. These systems are responsible for making sure turbines are operating efficiently and for protecting turbines from damage.
A large area of the DS3800NPSJ1B1B is filled with a variety of small components. Many small capacitors, diodes, and resistors are located all around the DS3800NPSJ1B1B. Most of the small resistors are blue and are banded in a variety of colored stripes. Some of the resistors are solid colored. These are mostly reddish brown or blue. The DS3800NPSJ1B1B contains many various capacitors. Many of these capacitors are silver and they are a variety of sizes. Several capacitors which are larger are also located on the DS3800NPSJ1B1B. Near the edge of the DS3800NPSJ1B1B there are two (2) larger yellow capacitors. These capacitors are lined up next to each other near the edge of the DS3800NPSJ1B1B. Sitting next to these yellow components there is one (1) larger silver capacitor. Situated on a different edge of the DS3800NPSJ1B1B is another mid-sized silver capacitor. The DS3800NPSJ1B1 also has five (5) integrated circuits. Each integrated circuit is identified with its part number, LM148D/8838. Along one edge of the DS3800NPSJ1B1B is a series of eleven (11) test points. The test points enable the user to test the board to make sure it is operating properly. One (1) orange LED (light-emitting diode) can be seen near one of the board’s edges.
