ABB AI620 analog input 16Ch 12 bits

• Support for a number of new, popular

communication protocols, e.g. Advant

Fieldbus 100, Profibus DP, LONWorks

and Allen-Bradley's DF1.

These make your new controllers able

to use ABB's new S800 I⁄O system and

easily able to communicate, with other

external controllers, with ABB's variable

speed motor drives and with smart

motor-control centers.

• More backup redundancy available,

e.g.:

- Smarter solution to CPU redundancy,

eliminating critical, common, components,

- Full dual redundancy, covering,

media and communication in interfaces,

for S100 I/O and Advant

Fieldbus 100.

I/O is the central process interface for Advant

Controller 400 series process controllers. Thanks to

built-in cablemarshalling facilities and parallel

communication with the host controller, it is the

right choice for centralized I/O systems and

high-speed applications.

The range of process I/O modules is complete,

consisting of general purpose digital and analog

inputs and outputs and special interfaces for special

tasks. These specials include pulse counting,

frequency measuring, positioning, motor speed

control and communication with other controllers.

All I/O modules provide simple interfacing, accurate -

yet fast - control, and easy integration of individual

loops into a comprehensive plant-wide control

and supervision system.

The interface modules connect to the process

through screw terminals on connection units

normally installed inside, at the back of the cabinet.

This solution keeps noise and destructive voltage

spikes away from the central electronics and

provides a neat and tidy process interface that is

easy to maintain.
