The S900 remote I/O system communicates with 800xA or other controllers over PROFIBUS. Suitable for applications in the chemical, pharmaceutical, oil and gas industries, S900 I/O can be installed in hazardous areas, thereby reducing marshalling and wiring costs. Further maintenance savings can be achieved through S900’s extended diagnostics and the use of HART®-compliant field devices. Three series of S900 I/O are available: − S-series for applications in Zone 1 hazardous areas − B-series for applications in Zone 2 hazardous areas − N-series for applications in non hazardous areas Additional solutions for specific applications are available: − Field housing - for wall mounting and field mounting in Zone 1 installations with system approval fully certified in accordance with ATEX. The high-grade steel housing is prepared for wall-mounting with facility for insulated screen rails or terminals. − CB220 compact box - S900 in compact form (with up to 4 I/O modules). This variant is suitable for use in applications such as temperature multiplexers and solenoid valve circuits. System 800xA Hardware S900 I/O The S900 components are based on a passive backplane suitable for mounting on a DIN rail or directly in a sub-distribution board. The passive backplane includes internal bus communication, terminals for field circuits, communication, and power supply. The function modules are plugged into the backplane in their appropriate slots. The redundant backplane has two slots for power supply units, two slots for communication interfaces, and 16 slots for function modules. Digital function modules have up to 8 channels, analog modules up to four. Therefore, when using a redundant backplane, 128 digital or 64 analog channels can be connected per station. In the case of the S and B series, up to ten S900 stations can be connected on a single fieldbus line. Key S900 benefits include: − Intrinsically safe - can be installed in Zone 1 and Zone 2 areas. − Good price/performance ratio because external barriers have been removed and costs are reduced in terms of cabling, installation, hardware, and maintenance. − High reliability thanks to smooth automatic transfer of data and to auto-diagnostics. − Easy configuration using either FDT/DTM or GSD files, allowing easy integration with 800xA process control systems. − High availability of the plant thanks to redundancy and hotswap capability of all components during operation.
