Thanks to its broad connectivity it fits a wide range of process
controllers and PLCs 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 cab ling. 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.
