GE (General Electric) created the DS3800VCB as a part of the MKIV (Speedtronic Mark IV) series for turbine controls. The DS3800VCB is what is known as a printed circuit board, or PCB. The MKIV was the third system to be made for the Mark series after Mark I and Mark II. The Mark IV series was designed to perform all of the required operations for turbines. MKIV is used in both steam and gas turbine systems. MKIV both automates and controls the processes of the turbine.
State of the art technologies were used in the development of the MKIV. The Mark series was in use as far back as 1968. The technologies that went into the creation of this series date back to the late 1940s. MKIV regulates startup, shutdown, and cooldown as well as fuel injection rate and temperature of turbines. The MKIV features its very own built-in system of diagnostics. This system informs the operator about any problems with the system. An onboard printer is also featured on the MKIV. This printer also creates timestamped reports. The user can use these reports to determine what went wrong with the turbine and when. This also creates a written log which an operator can refer back to. This printer also has the capability to print anything displayed on the system’s screen. Many different printed circuit board components may be featured on the surface of the DS3800VCB board. These can include resistors, diodes, capacitors, jumpers, test points, transistors, inductors, fuses, LEDs (light-emitting diodes) or other circuit board components.
