Reer MOSAIC M1 Installation And Use Manual page 134

Parameters
Output Type: There is a choice of 2 different output type:
•
Single Output Type
• Double Output Type
Using MOSAIC M1S, MOSAIC M1S COM, MI8O4, MO4L, MO4LHCS8 modules, the operator can
choose between different configurations:
1. Four SINGLE OUTPUTS function blocks (single output type)
2. Two SINGLE OUTPUTS function blocks (double output type)
3. Two SINGLE OUTPUTS function blocks (single output type) + one SINGLE OUTPUTS function
block (double output type)

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).
Example of project - 2 single output type function blocks + 1 double output type function blocks
Here below you can find the explanation of the MOSAIC M1S, MOSAIC M1S COM, MI8O4, MO4L,
MO4LHCS8 SINGLE-OSSD configurations.
Manual Reset: If selected this enables the request to reset each time the input signal falls. Otherwise,
output enabling directly follows In input conditions.
