About the DS3800HXFC1J1E

The DS3800HXFC1J1E is a PCB manufactured by GE for the MKIV series.  The Mark IV is one of GE’s steam or gas turbine management systems. It was their third commercially available Speedtronic system and the first to be built around a series of integrated computer systems that worked together to monitor the turbine for problems (loss of flame, high pressure, fire, etc.) and to manage procedures like start-up, temperature control, and shut down.  

The DS3800HXFC1J1E is built with over forty circuits.  Included in this number are hex/quad D flip-flops with a typical clock frequency of 40MHz and typical power dissipation per flip-flop of 14 mW, quad 2-input NOR gates with low power Schottky, and tri-state buffers/line drivers with 400 mV of hysteresis at each low current PNP data line input.  

The DS3800HXFC1J1E is built with a 218A4553-1 AMP 533002-1 8728 connector (female, right-angled,) an M83503/24-19 8535 connector (male, right-angled,) and a vertical male pin connector. This connector is designed to connect to an optional auxiliary board, which, if installed, will be supported by four vertical nylon pins inserted into the surface of the DS3800HXFC1J1E.   The board has one toggle switch, four test points, two red LEDs and one amber LED.

There are six network arrays populating the DS3800HXFC1J1E.  Resistors tend to be ceramic covered metal film. The board has eight jumper switches.  Several of these switches may be set between zero and one.

All technical support for the DS3800HXFC1J1E was provided by GE.  This includes publications like data sheets and manuals.
