DS3800NRMA

About the DS3800NRMA

The DS3800NRMA is a PCB designed by GE for the Mark IV.  The MKIV was created for gas/steam turbine management and is built with multiple interconnected microcomputers that continuously monitor the turbine system for issues like loss of flame, vibration, and fire, and then makes adjustments as needed to protect the turbine and keep it running.  It is also possible to use the MKIV to automate procedures like control sequencing and speed control.

The  DS3800NRMA is built with two PCB mating connectors.  This includes one right-angled female connector on its left edge and one 17-pin right-angled male connector parallel to its right edge.  It is worth noting this second connector is designed to sit above the surface of the board and will connect to another board that will sit over the edge of  DS3800NRMA. The board also has one four by six Augat plug.

The  DS3800NRMA has twelve TP test points.  It is marked with the code 6BA04. It is marked with triangles and letters on one edge and has been drilled at each corner.  Extractor clips are installed in two of these. The board has two board stiffeners installed along both long edged. Board stiffeners minimize flexing and the chance that the PCB will crack or have damage.

The  DS3800NRMA has five amber LEDs and three red LEDs.  The board is built with eighteen transistors. It has ten board-to-board pins located near the center of the board, near four nylon vertical pins.  

Twenty-one circuits populate the board.  It has several polyester vinyl capacitors and several lines of metal film resistors.   Tech support for the DS3800NRMA was provided by GE.
