Description

The remote S900 I/O system can be installed in a non-hazardous zone or directly in Zone 1 or Zone 2, depending on the selected system variables. S7-1200 Programmable controller. I/O systems can be installed directly on site, reducing marshalling and cabling costs.

The system is stubborn, fault-tolerant, and easy to serve. The integrated disconnect mechanism allows for replacement during operation, which means that the power supply unit can be replaced without interrupting the main voltage.

S7-1200 Programmable controller. Used to connect local security field devices installed in zone 2, Zone 1, or zone 0.
