AC 800M – General Section 1 Introduction
28 3BSE 027 941 R301
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 removable cover attached with screws. The baseplate,
which is always mounted onto the DIN-rail, carries the majority of the connections
to processor, the power supplies and communication interfaces, as well as to the
external buses and systems.
The AC 800M Controller is designed to be a cost-effective, low-maintenance
solution for applications ranging from small Programmable Logic Controller (PLC)
to advanced Distributed Control Systems (DCS) control applications.
