Features
The major features of the S800 I/O system are:
• Communicates over PROFIBUS-DP/DPV1 or Advant Fieldbus 100.
• Quick fault-finding with the 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 by a mechanical keying arrangement from
destruction such as if an attempt is made to insert a module type in a position
with a different key code rather 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.
