Derating of the input currents
The table below shows the maximum permissible input current of the distributed I/O systems
depending on the ambient temperature.

Note
Adherence to the minimum clearance
The I/O devices may be used at an installation distance of 2 cm up to max. 60 °C ambient
temperature.
If the installation distance to other devices or objects is less than 2 cm, the ambient
temperature must be reduced by 5 K (for example, 60 °C ⇒ 55 °C). This must also be taken
into consideration for the derating diagrams of the device manuals.
