GE DS3820MAUD Mark IV System Bus Module

GE DS3820MAUD Mark IV System Bus Module

Part Number DS3820MAUD Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockThe DS3820MAUD is a Human-Machine Interface based on a PCB designed by General Electric. It's a gas turbine system component from the Mark IV generation. It has a control panel and this panel connects to the DS3800HMAC PCB. The panel has three cutouts and is labeled DS3820MAUD. Cable A OK, Cable B OK, and Watch Dog Timer OK are the three cutouts. There are additional lines that point to ports that protrude from the panel's edges. These lines are called Cable A, with JB and JC on one end and JB and JC on the other. Cable B is the other line, which is branded JD on one end and JE on the other. At the top of the panel, there are two boxes. 

JA/Link Controller Connector and JG/Power Connector are the labels on these connectors. Four ports for attaching cables are located on the panel's side. These are the same as the JB, JC, JD, and JE described above. Six screw connectors link the panel to the PCB below these ports. Two pins that slide over two vertical nylon spacers connected to the board connect the rear side of the interface panel to the panel. Six red LEDs are incorporated inside the DS3800HMAC PCB. The cutouts on the panel above correspond to these. One PCB mating connector (218A4837-P12,) a six-pin header, and six TP test points are included on the board. There are ten jumper switches, two transistors, and forty integrated circuits, including crystal oscillators, in this device.

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.  

The IO module has the following main functions

Input Function

The IO module can receive input signals sent by external devices and convert them into digital or analogue signals for use by the computer system or control system. These input signals can come from a variety of sensors, such as temperature sensors, pressure sensors, photosensitive sensors and so on. By receiving and parsing these input signals, the system can monitor and control the external environment in real time.

Output Functions

The IO module is capable of converting the output signals generated by a computer system or control system into the form required by an external device. These output signals are typically used to control actuators such as motors, valves, lights, etc. By sending appropriate output signals to external devices, the system enables control and operation of the external environment.

Data Acquisition and Processing

The IO module is capable of acquiring data from external devices and transferring it to a computer system or control system for further processing. This enables the system to acquire environmental data, status information and user inputs in real time and make appropriate decisions or perform specific tasks based on these data.

Communication Interfaces

IO modules are usually equipped with different types of communication interfaces, such as serial interfaces (RS232, RS485), Ethernet interfaces, CAN bus interfaces, and so on. These interfaces enable IO modules to exchange data and communicate efficiently with computer systems or other external devices.
