DS3800NVIA

About the DS3800NVIA

The DS3800NVIA circuit board is part of General Electric’s Mark IV Speedtronic series.  The Mark IV was the first Speedtronic system to use microcontrollers.  It was also the first to offer triple modular redundant architecture, where three individual controllers voted on outputs.  With this sort of setup, any one controller could be offline due to an issue or maintenance without affecting the overall system. 

The DS3800NVIA is a rectangular single-sided board with components mounted on one side only.  The board uses through-hole components.  Standoffs have been pre-installed on the board to allow for the installation of auxiliary boards. However, it is important to note these auxiliaries are not part of this purchase.    The board is also pre-drilled to allow for mounting and carries several codes that will help you determine proper placement and wiring configurations. 

The DS3800NVIA has many components mounted to its surface.  This includes Augat connectors, integrated circuits, resistors, capacitors,  test points,  transistors, and diodes.  The board also has a line of numbered pins that will help the auxiliary board interface with the main board.  Additionally, the board has five LED indicators.  Four of these are red and one is yellow.  

The DS3800NVIA has a single backplane connector.  It also has three toggle switches located in its bottom right corner.  These are labeled ground reset, OV reset, and OV test.   

Additional information about the DS3800NVIA can be found through original documentation from General Electric.  This includes user guides, manuals, and data sheets.  If you need replacements of any of these documents, please reach out to our staff.
