Product Description

The DS3800HMPF1C1B is a controller module designed to fit into General Electric’s Mark IV control system.  The Mark IV is one version of GE’s successful Speedtronic system for the control of industrial gas and steam turbine systems.  Speedtronic systems began with the Mark I in the 1960s.  The Mark IV was the first of these systems to offer triple modular redundant control. 

The DS3800HMPF1C1B is one of the earlier controller modules. It is built around an IMB 8086 microprocessor chip.  This chip uses a 40-pin package and HMOS technology.  It can transfer data as 8-bits or 16-bits in one bus cycle.  This was a third-generation Intel product designed to fetch instructions from memory, read, execute, and write the result if necessary.  

The DS3800HMPF1C1B is only one available controller module for the Mark IV.  It works in conjunction with two other controllers in a triple modular redundant architecture where all data is voted before it is used for outputs or for control. 

The DS3800HMPF1C1B is designed as a rectangular board that has been factory drilled in each corner.  Two corners have been fitted with extractor clips.  This board edge also includes a right-angled connector, two LEDs, and several jumper switches.   The opposite board edge is fitted with a backplane.  The board is designed with a vertical connector and standoffs to allow the addition of an auxiliary board if desired.  Other board components include resistor network arrays, integrated circuits, capacitors, and resistors.  The board is marked with its board ID and with the General Electric logo.
