About the DS3800HUMC

The DS3800HUMC is a rectangular circuit board that was originally designed and marketed by General Electric as part of their Mark IV system.  The MK IV Speedtronic system was designed by GE to control and manage gas and steam turbine systems of various sizes and complexity.  These turbine systems offer decreased downtime through the use of three independent microprocessor-based control sections that each back up the other two control processors. 

DS3800HUMC board is manufactured with two lines of jumper switches located parallel to one of the short board edges.  There are over thirty jumper switches on the board.  These are designed to allow technicians to configure board settings as needed by the end user.  Jumpers are typically set in the default settings (most used) at shipping.  However, before removing your previous board from its position, your current jumper settings should be noted and duplicated on your replacement board.  This is to ensure all settings are duplicated as required by your particular system’s needs. 

The front edge of the DS3800HUMC has a single toggle switch located near one of two LED indicators on this board edge.  One LED is red, the other is yellow.  This edge also has a right-angled connector.  The factory-made holes located in each board edge have been fitted with extractor clips.    The opposite board edge is also factory drilled and is populated by a single backplane connector.  

Other board components on the DS3800HUMC include multiple pin connectors that are used to mount small daughter boards, resistor network arrays, integrated circuits, resistors, and integrated circuits.
