General Electric manufactured the DS3800HSCJ to be a part of the Speedtronic Mark IV series which is used to regulate the operation of gas and steam turbines. The Mark IV system, as well as the earlier Mark systems, have been in use for decades since the development of the Mark I system in the 1960s. The technologies used in the Mark systems have been developed since the late 1940s. The Mark IV system controls fuels in accordance with the requirements of speed or load control. The system controls temperatures and sequences auxiliaries for fully automated startup, shutdown and cool down. The Mark system also protects against adverse operating situations and operating conditions. The system can also monitor emissions of water, fuel, and air. DS3800HSCJ is a high level isolator circuit card. Isolator circuit cards are used to protect people, circuits, and equipment from shock and short circuits. These isolator cards can also eliminate group loops, protect circuits from faults, get rid of conducted noise and let safe and accurate measurements to be taken.
The DS3800HSCJ isolator circuit card contains a number of different circuit board components. A number of various diodes, resistors, capacitors, transformers and transistors can be found throughout the DS3800HSCJ. Each component is connected to the circuit through a series of traces etched into the surface of the board.
Technical support and troubleshooting for the DS3800HSCJ were originally provided by General Electric. This includes any manuals and data sheets. If technical support for the device is needed, General Electric should be consulted.
