S900

The remote S900 I/O system can be installed directly

in zone 1 and zone  hazardous areas.

It communicates with the control system level using

the Profibus standard, therefore reducing marshalling

and wiring costs. The system is sturdy, error-tolerant

and easy to service. Moreover, the S900 I/O system

is characterized by a compact design, cyclical trans

mission of secondary HART variables, parameteriza

tion and diagnosis of all HART field devices via the

fieldbus. Its redundancy ensures maximum availability.

Integrated disconnection mechanisms allow replace

ment during operation, meaning that there is no need

to interrupt the primary voltage in order to exchange

the power supply units. Thanks to its sturdy, space

saving design and stable casing that is suitable for

any environment, S900 is the best and most cost

effective I/O system for use in zone 1 and  hazard

ous areas.
