Connection examples for safe
outputs
6.1
Explanation of the examples
Depending on the type of wiring, the outputs of a module can achieve different safety
integrity levels (SIL, SIL CL, Cat., PL) simultaneously (as long as the settings do not
contradict one another).
The following examples only describe the options for the electrical connection of
controlled devices/actuators to the safe outputs.
Should you have any questions regarding applications to be implemented, please contact
Emerson.
The following are specified for each example:
•
Basic specifications
The main data for the example is specified in the table.
•
Device diagnostics and behavior of the module in the event of an error
Diagnostic capability depends on the parameterization.
If a message is transmitted to the controller in the event of an error, the message is
specified in the tables. For information on the relevant error code, possible solutions,
and information as to whether acknowledgment is required, please refer to Section
"Errors: messages and removal" on page 50.
•
Typical parameterization
The table illustrates an example of all the parameters for the specified assignment.

Not evaluated
Errors (cross circuits, short circuits), which can be prevented by correct installation (e.g.,
protected cable installation, isolated cable installation, double insulation, use of ferrules)
are not described in the following tables.
