The maximum achievable SIL/SIL CL/Cat./PL is specified in the table.
In order to achieve this:
•
Observe the information in the connection examples (see
"Connection Examples for Safe
•
Observe the requirements of the standards with regard to the external wiring
and the actuators to be used to achieve a SIL/SIL CL/Cat./PL (see
Required to Achieve a Specific Safety Integrity Level" on page

Key:
*
If the test pulses are disabled, a cross circuit between the outputs is only detected
if the output is enabled.
To achieve Cat. 3, two-channel actuators are usually used.
