If the DIQ/S 28X [-XX]/24V is operated at an ambient temperature below 47 °C
(117 °F), the operator has to make sure that the total power requirement P (con-
tinuous) is not more than 6.5 W.
If the DIQ/S 28X[-XX]/24V is operated at an ambient temperature above 47 °C
(117 °F), the allowed total power requirement P (continuous) is linearly reduced
to 4 W at 55 °C (131 °F).
