Connection options for actuators depending on the
parameterization
Actuators that meet various safety requirements depending on the parameterization can
be connected to the outputs. For connection examples, please refer to Section 6,
"Connection examples for safe outputs".
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 safe outputs")
–
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)
"Output" parameterization
Test pulses
Achievable category
For connection example, see
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.
