1.4.4 Relationship between Continuous Simultaneous ON
Ratio and Ambient Temperature
If the number of I/O points which turn ON at the same time exceeds the
specifications range, the unit may be damaged.
The graphs below show the relationship between the ambient temperature and
the continuous simultaneous ON ratio.
