Connection options for actuators depending on the
parameterization
Actuators that meet various safety requirements depending on the parameterization can
be connected to the relay outputs and the output modules in the safety-related segment
circuit. For connection examples, please refer to Section 6, "Connection examples for the
safe relay outputs and the safety-related segment circuit".
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 Section 6, "Connection
examples for the safe relay outputs and the safety-related segment circuit")
–
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 "Measures required to
achieve a specific safety integrity level" on page 6-3)
