°C to max. temperature (see
comments)
-40 °C to 60 °C
(corresponds to a depth of
approximately -1 000 m)
(corresponds to an elevation of
approximately 4 000 m)
Comments
Observe any load-dependent limitations.
Refer to the documentation of the employed component.
The maximum permissible upper temperature depends on the
BusAdapter used.
Tested according to IEC 60068-2-2 (Dry heat)
The cooling effect of air depends on the density of the air. The
locally occurring air pressure (operating altitude) might restrict the
maximum permissible ambient temperature. The density of the
air decreases with increasing altitude.
The cooling effect of air corresponding to the typical operating
altitude is shown in the following derating table.
Without condensation, corresponds to relative humidity (RH)
stress grade 2 in accordance with IEC 61131 part 2
Tested according to IEC 60068-2-78 (Damp heat)
