ABB IndustrialIT System 800xA S800 I/O System
S800 I/O is a comprehensive, distributed
and modular process
I/O system that communicates with parent controllers over
industry-standard
field buses. Thanks to
its broad connectivity
it fits a wide range of
process controllers
from ABB and others.
By permitting installation in the field, close
to sensors and actuators, S800 I/O reduces the installation
cost by reducing the
cost of cabling. And
thanks to features
such as “hot swap” of
modules, “on-line”
reconfiguration and
redundancy options,
it contributes to
keeping production –
and thereby profits –
up.
