Analog Control Board (ACB)
The 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.
