About the DS3800NSCE1B1A

The DS3800NSCE1B1A is a PCB created by GE for the Mark IV series.  The MKIV was GE’s replacement for the earlier MKI and MKII Speedtronic systems, which also managed gas and steam turbine systems.  The MKIV vastly improved upon these earlier systems by using distributed control functions built across multiple platforms run by microcomputers.  These independent-but-linked platforms monitor and protect the turbine system from such issues as vibration, fire, and high pressure. With improved reliability resulting from such management, the MKIV has a much lower rate of turbine outage than previous Speedtronic systems.

The DS3800NSCE1B1A has very few components built on to a small board.  It is marked on two edges, once with the board’s identification number and with the code “6BA01,” and once with the letters MAC.   The board has been drilled in four places, near but not in each corner. Screws are inserted in this drill points.

The DS3800NSCE1B1A has one twenty-pin male (vertical) connector.  It also has one female twelve-pin (vertical) connector. The connectors have been labeled JA and JM respectively.  The board has one connector point, which is labeled J1, and one TP point.

The DS3800NSCE1B1A is built with a line of spare PTH, or plated through-holes.  Next to this, the board has six trim potentiometers. Finally, the board has nine resistors, including three made of metal film and six of carbon composite.  While there are only nine resistors on the board, these components have been marked “R20” through “R28.”
