  SM811K01 Safety CPU module

• Long Description:

  High integrity, certified for SIL3. Requires configuration according to
  Safety Manual. Local organizations must comply with the Qualifications
  to secure successful sales of ABB safety systems, to order safety
  equipment.Collaborting safety CPU with the PM865. Connects to CEX bus after BC810
  CEX bus interconnection box. Including:
  - SM811, Safety Module
  - TP868, Baseplate
  - TK852V10, Syncronization link cable

  Note! This part is not RoHS 2 2011/65/EU compliant.
  This is a spare part for systems placed on the market before July 22,
  2017 and may only be ordered for repair, reuse, updating of
  functionalities or upgrading of capacity.
  For new installations, please order SM812K01 instead.”

  The prime function of SM811, is to provide intelligent supervision of a controller during non-SIL and SIL1-2 operations, and together with a PM865 form a 1oo2 diverse structure for SIL3 applications.For high availability applications it is possible to have redundant SM811´s that work together with any of the two redundant CPUs. SM811 has a dedicated synchronization link to synchronize active and redundant SM for hot-insert and online upgrade. It is needed during hot-insert and online upgrade situations to copy data between two SM811s in a redundant setup.

  The SM811 has a connector with three digital inputs and two digital outputs that can be used for safety-related digital I/O (not process I/O).
