S900 remote I/O

The remote S900 I/O system can be installed directly in zone 1 and zone 2 hazardous areas.

S900 I/O communicates with the control system level using the PROFIBUS standard.
The I/O system can be installed directly in the field, therefore the costs for marshalling and wiring are reduced.

The system is sturdy, error-tolerant and easy to service. Integrated disconnection mechanisms allow replacement during operation, meaning that there is no need to interrupt the primary voltage in order to exchange the power supply units.

S900 I/O features include:

  • Remote I/O system for hazardous areas
  • Redundancy for maximum availability
  • Hot-swap capability of all components during operation
  • Extended diagnostic functions to reduce maintenance efforts
