Analog Control Board (ACB) The Analog Control Board (ACB) is the hub for all control-level signals external
to the drive. The drive routes analog I/O, external fault signals (through the XIO
board), DPI communication modules, remote I/O, terminal interface, printers,
modem, and other external communication devices through this board.
