About the F31X139APMASG2

F31X139APMASG2--Micro Application Board

The F31X139APMASG2 is a Micro Application board fabricated by General Electric to fit into their general purpose drives like the DC-300.  Currently, these drives are considered obsolete. However, when they were initially released they were designed to be flexible and dynamic systems capable of a number of tasks within industrial settings.  The F31X139APMASG2 is part of the 531x series of boards and has a second board number, 531X139APMAR7.

The F31X139APMASG2 contains a combination of analog interfaces between external equipment and the system’s Control Card.  These interfaces allow the core drive to be expanded to handle optional functions. These interfaces include inputs and outputs, along with five programmable signal-level-detector relays.

The F31X139APMASG2 has four terminal strips with 18 screw connections total between the four.  It has four header connectors and three male vertical pin cable connectors. There are over forty jumper switches located on the surface of the board.  Jumper settings may be found through series user guides. If you are replacing this board in your system, it is highly recommended you make note of the current jumper settings on the old board in order to duplicate these on the replacement board.  Boards are typically shipped with jumpers set to factory defaults.

The F31X139APMASG2 is populated by eight potentiometers, over thirty-five resistor network arrays, and over fifty integrated circuits.  Resistor network arrays and potentiometers are typically used for voltage division. Most ICs are marked with their manufacturer part number.  The board has a single red LED indicator. Other components on the board include capacitors, diodes, and resistors. More information on the board, including installation procedures, may be found through manuals  or datasheets originally distributed by General Electric.
