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.
