Different output
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.
