The 531X171TMAAEG2 is a Micro Application Terminal Board developed by General Electric.

The connection terminals for the majority of signal I/O are present, along with interface circuitry. Cables link the board to the drive control board.

There is a connection on the GE Terminal Board Relay Card for attaching several signal lines to the board. The board performs the same tasks as the original boards and is a replacement for a number of boards.
