About the 531X139APMALM7

The 531X139APMALM7 is a printed circuit board component made by GE to fit into various systems, including several general purpose drive systems like the DC-300 or the AC-300 drives. These drives were originally designed for use in industrial applications.The 531X139APMALM7 functions as an ISO Micro Application Card. There are several versions of this card in the 531X series. This is a large board that is dense with components. It has several codes printed on the board surface, including a secondary F31X identification number. 531X139APMALM7 has eight potentiometers. Four of these are placed in the bottom left corner of the board and are labeled AN1 SCL, AN2, P1, and P2. The board has a single LED indicator. This indicator is red and is located in the bottom right quadrant. There are over thirty resistor network arrays used, along with traditional metal film resistors. Most capacitors are made from ceramic material. The 531X139APMALM7 communicates with other boards through its three terminal strips (one three-position and two six-position,) its four header connectors, and its two vertical pin male cable connectors. Other components on the board include:

• over 45 integrated circuits
• four relays
• jumper switches
• TP test points
• diodes
