2.5 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/SILCL/Cat./PL is specified in the table.
In order to achieve this:
– Observe the information in the connection examples (see Section 6, "Connection ex-
amples 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/SILCL/Cat./PL (see “Measures required to
achieve a specific safety integrity level” on page 57).
Key:
Output OUT0 to OUT3
“Output” parameterization Single-channel Two-channel
Test pulses Any ON/OFF*
Achievable category SIL 2 / SILCL2 / Cat. 3 / PL d SIL 3 / SILCL 3 / Cat. 4 / PL e
For connection example, see
page
59 62
* 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.
