The major features of the S800 I/O system are:
• Communicates over PROFIBUS-DP/DPV1 or Advant Fieldbus 100.
• Quick faultfinding with help of LEDs of each module and channel.
• An extensive scope of Digital input/output modules and Analog input/output modules.
• Digital input/output modules and Analog input/output modules with Intrinsic Safety interfaces.
• Mounted on standard DIN rails type NS 35/75 according to EN 50022.
• Support of dual redundancy in power supply, fieldbus connection and I/O channel.
• Support of fieldbus media supervision, bumpless change-over and failure reporting.
• All outputs can be individually set to freeze or to take on predefined values.
• Easy connection to drives systems, minimizing communication delays and cost.
• All modules have plastic injection molded enclosures which provide safety protection degree IP20 according to IEC 529. The plastic used is halogen free.
• I/O modules are protected from destruction by a mechanical keying arrangement if an attempt is made to insert a module type in a position with a different key code than the factory set code of the I/O module. Terminal units have keys which are set to key code of its I/O module’s key code. (S800L I/O modules do not use Termination Units).
• An electrical ID is checked at start-up, if this does not match the configured type, the I/O module is not taken into operation.
• Hot-swap of S800 I/O modules (except S800L modules) allowing replacement of faulty modules without disconnecting field power or system power to the I/O-station.
• HART pass-through communication.
