About the DS3800NVCD

The DS3800NVCD is a Mark IV General Electric Conditioning circuit board.  The Mark IV turbine control system was the first Speedtronic system to offer triple modular control for industrial gas and steam turbine applications.   The Mark IV’s digital control was a significant improvement over previous analog control systems.   It used built-in redundancy created through the use of three microprocessor controllers and a communications <C> microprocessor.  The three controllers independently vote on inputs like Overspeed, valve position, and temperature to decide how the system will respond. 

The DS3800NVCD board is a rectangular board that has been factory drilled to allow for mounting.  The board does not include any sort of faceplate but does have an extractor clip inserted into one predrilled hole on its leading edge.   The opposite edge has a long backplane connector that will allow the board to communicate with other boards within the rack system. 

The DS3800NVCD board is populated with multiple components including two larger transistors mounted into heat sinks.  These use surface wiring to interface with the board.  The board also has a smaller transistor, multiple integrated circuits, resistors, capacitors, and a right-angled connector for a ribbon connector.  This connector has clips to help maintain the connection to the ribbon connector.
