About the DS3800HMPF1E1D

The  DS3800HMPF1E1D  is a controller module designed to fit into a Mark IV Speedtronic system from General Electric. The Mark IV was the first of these systems to offer triple modular redundant control where the system used three controller modules to vote on all data before it was used for outputs. 

The  DS3800HMPF1E1D is only one kind of controller available for the Mark IV system. Other controllers include HXPC, HRMA, HPRA, HAIA, NTCA, NVCA, and HSAA boards.   These work in conjunction with communicator modules in a <C> <RST> format, with the <R> <S> and <T> boards being independent of each other but exactly the same, with their own inputs, outputs, and power supply.  

In this sort of configuration, the  DS3800HMPF1E1D is designed to create its own independent assessment of turbine condition, which is then sent to the controller.  This information is voted upon using data from all three boards, typically needing two out of three boards to “agree” on each critical action.  

The  DS3800HMPF1E1D is built around an Intel 8086 microprocessor chip.  This is a third-generation chip that offers a hierarchical bus organization and distributed system functions with a 16-bit external data path.  

For a more detailed look at the  DS3800HMPF1E1D circuit board or for additional information about the Mark IV system, please refer to and review manuals, user guides, and data sheets from General Electric.  These were typically made available to you with your original purchase from the OEM.
