Description
57C331 is the sixteen-slot mechanical and electrical backplane for an AutoMax or DCS 5000 controller installation. It houses the power-supply, processor, I/O and special-purpose modules that make up the configured control system.

The P1 connector follows the IEEE P796 Multibus arrangement and the P2 connector uses the documented modified P796 bus. Together they distribute power and provide the intermodule signal paths required by the installed AutoMax/DCS 5000 modules.

Up to four compatible AutoMax processors can be used in a rack when the documented common-memory arrangement is provided. AutoMax 57C430-series processors and DCS 5000 57C407 processors must not be mixed in the same rack, as stated in the official rack instruction.
