6 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 integ-
rity levels (SIL, SILCL, 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
the Phoenix Contact safety hotline (see “Safety hotline” on page 15).
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 safe controller in the event of an error, the message
is specified in the tables. For information about the relevant error code, possible reme-
dies, and information about whether acknowledgment is required, please refer to Sec-
tion “Errors: Messages and removal” on page 69.
– Typical parameterization
The table illustrates an example of all the parameters for the specified assignment.
Key for all tables in this section:
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.
Therefore, for example, only errors between outputs, which are on the same plug, are de-
scribed. For example, in the event of correct installation, cross-circuits with outputs of other
connectors cannot occur.
