ABB 07 KR 51 24VDC 1SBP260010R1001  Central units

The AC 31 brings accessibility to beginners and experienced automation users alike, for any

application with 14 to 1000 inputs / outputs and more, using the same set of basic

components.

From a compact machine fitted with a few automated functions to large installations spread

over hundreds of meter, and even kilometers, the AC 31 can fit your requirements.

It is therefore possible to realize distributed applications throughout a site, a workshop, or a

machine where each component (input / output unit, central unit) is close to the sensors /

actuators. The whole setup is connected by a single twisted pair over which all information

from the sensors is sent after processing by the central unit to the actuators, as well as

distributed intelligent units. The following communication interfaces are available, to extend the

AC 31’s possibilities and integration with the company's other automation systems:

MODBUS
, ASCII, ARCNET
, RCOM, AF100. The developments in this field are continual.

An ABB AC 31 system always includes an AC 31 central unit. There are three types of central

units:

- The 40 series central unit, with a local inputs / outputs extensions interface

- The 50 series central unit, with a local inputs / outputs extensions interface

and a CS 31 bus interface

- The 90 series central unit, with a CS 31 bus interface

Each central unit incorporates a specific number of binary inputs / outputs and occasionally

analog. It is possible, depending on the central unit, to increase the number of inputs / outputs,

to add input / output extensions connected directly to the central units or remote input / output

units via the CS 31 twisted pair.
