Different output configurations (configurable with MSD configuration software)
can be set:
• 4 single channels (1 Safety Output per channel with its relative feedback input).
• 2 dual channels (2 Safety Outputs per channel with their relative feedback input).
• 1 dual channel and 2 single channels.
Using single channels OSSD, to maintain Safety Integrity Level (SIL) "3" requirements the OSSD
outputs must be independent.
Common cause failures between OSSD outputs must be excluded by observing an appropriate
cable installation (i.e. separate cable paths).

External devices cannot be connected to the outputs unless explicitly planned in the MSD
program configuration.
