Product Description

The DS3820MAUD is an HMI built upon a PCB that works within the Mark IV series.  The Mark IV designed to manage steam/gas turbine systems.

The DS3820MAUD has the following specifications and components:

  • It has an interface panel.  This panel connects to the PCB identified as DS3800HMAC.   The panel is identified as DS3820MAUD and has three cutouts.  These cutouts are labeled Cable A OK, Cable B OK, and Watch Dog Timer OK.   It also has lines that point to ports that protrude from the edges of the panel.  These lines are labeled Cable A, with one end of the line labeled JB and the other JC.  The other line is labeled Cable B, with one end of the line labeled JD and the other JE.   There are two boxes at the top of the panel. These are labeled JA/Link Controller Connector and JG/Power Connector.   The middle of the panel states “General Electric. Directo-Matic Plus. Control System Freeway Media Access Module.”

  • The side of the panel has four ports for connecting cables.  These correspond with JB, JC, JD, and JE mentioned above. Below these ports are six screw connections which hold the panel to the PCB.

  • The back side of the interface panel connects to the panel via two pins that slide over two vertical nylon spacers connected to the board.

  • The DS3800HMAC PCB is built with six red LEDs.  These line up with the cutouts in the panel above.  The board has one PCB mating connector (218A4837-P12,) a six-pin header, and six TP test points.  It has ten jumper switches, two transistors, and forty integrated circuits, including crystal oscillators.  

All technical support for the DS3820MAUD was originally provided by GE.
