Switching Inductive Loads
Defect by thermal overheating if the switching frequency is too high!
If the inductivity and load current you have selected is too high for the selected
switching frequency, it can lead to thermal destruction of the digital power output.
Destruction of the digital power output can cause the safety function to fail.
You can operate inductive loads on the digital power outputs of the PROFIsafe
I/O module by using the internal recovery circuit. Depending on the size of the
inductance of the load and the value of the load current, the switching frequency
specified in the technical data may be exceeded.
The following figure represents the maximum permissible inductance of the load
based on the load current and switching frequency.
