S800 I/O is an open comprehensive, distributed, process I/O system that communicates with controllers by direct connection or over industry-standard field buses. Thanks to its open 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.

Benefits

- Cost effective solutions to practically all needs for field device interfacing, including basic analog and digital I/O, as well as intrinsic safety and high integrity solutions.

- Highly modular and can be built in a near infinite number of ways, from highly centralized to highly distributed.

- Supporting industry standard field bus PROFIBUS DP, compatible also with non-ABB controllers; supports also ABB’s Advant Fieldbus 100

- Configured transparently as part of  parent controllers, like local I/O; no additional knowledge or skills are required.

- Comprehensive diagnostics, hot swapping of modules and redundancy solutions contribute to keeping production up
