1.7.4 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 specifi-
cations range, the unit may be damaged.
The graphs below show the relationship between the ambient temperature and the
continuous simultaneous ON ratio.
