About the DS3800NSWB1B1B

The DS3800NSWB1B1B is part of General Electric’s Mark IV Speedtronic gas and steam turbine control system.   The MKIV has a triple modular redundant architecture that will switch control of logic signals to the remaining two processors if one processor is unavailable for any reason.   This kind of designated voting allows the unit to remain online and working in more situations than earlier versions of the Speedtronic system. 

The DS3800NSWB1B1B is a Comparator board.  Comparators are used to compare voltages via incoming analog signals and using them to create an outgoing binary signal.   Boards like this one typically have superior switching time due to specific trim settings. 

The DS3800NSWB1B1B is built with two nylon ejector clips installed in the front corners.  These are used to push or pull the board in/out of place during installation or removal without the need to touch the board or components located on the board.  

The DS3800NSWB1B1B is built with a single yellow LED indicator and ten red LED indicators.  These are placed along the leading board edge and are separated by a line of test points. 

Other board components include resistor network arrays (used for voltage division), transistors, resistors, capacitors, and integrated circuits.  ICs are used for various operations.  Mounted ICs include octal buffers and line drivers.  

The edges of the DS3800NSWB1B1B are marked with a number of codes and other symbols to aid you with installation and operation.  Additional information is available within original documents from General Electric like manuals and user guides.  Let us know if you require replacement copies of these documents.
