* The SSSI signals from devices are available with release version 10. The signals are used,
for example, to connect an IO extender (order no. A5E01494354). Refer to the
documentation of the IO extender for more on this. If SSSI is not used, the lines are available
for their original function as digital inputs and outputs.
The following table is valid for devices up to and including release version 3.

Arc-suppression diode with inductive loads
If you connect inductive loads (e.g. valves) for digital outputs, you must connect the arc-
suppression diodes in parallel.
