Section 1 Product Overview

The AC 800M controller consists of a selection of units mounted on horizontal

DIN-rails, which can be housed within an enclosure. The majority of units consist of

a base mounting plate and a removable module attached with screws.

The hardware units that form the AC 800 M controller are:

• Central Processor unit (CPU)

• Communication interface modules for different protocols

• S800 I/O modules

• Power supply modules

Various I/O systems can be connected to the AC 800M controller, either directly

(S800 I/O) or via PROFIBUS or FOUNDATION.
