About the DS3800HMAC1F1E

The DS3800HMAC1F1E is one of several media access boards used within GE’s Mark IV turbine control system.   The Mark IV was a revolutionary version of General Electric’s Speedtronic turbine control system, as it was the first of the series to offer triple modular redundant control. 

The DS3800HMAC1F1E weighs approximately 0.98 pounds.  It is a rectangular board with a large vertical component along one edge.   The board is factory drilled along its edges for mounting.  Alignment markings are located here as well. 

The function of the DS3800HMAC1F1E is to manage data transmission between other devices within the system.  The unit is designed with multiple connectors including stab-on and right-angled pin connectors.   The vertical component is a red plate with four coaxial components; this component is marked as 206B3334G1.  

Modules within the Mark IV connect together using discrete wires, harnesses, and cables.  Wiring symbols can be found on each board that helps you understand how each component interconnects.  These connections are often marked with a three-digit number and a five-digit alphanumeric number that helps describe where the other portion of the connection is. 

Other board components on the DS3800HMAC1F1E include several jumper switches, integrated circuits, transistors, test points, and LED indicators.  Many of these carry markings that will give you additional information about the board and the individual components. 

For specific information regarding handling, installation, or maintenance, please refer to original documentation from General Electric.  This includes manuals and user guides.  AX Control can help you if you no longer have these documents at your disposal.
