Relationship between Continuous Simultaneous ON Rate and Ambient Temperature
There are restrictions on the power supply voltage and output load current imposed by the ambient temperature. Make sure that the power supply
voltage and output load current are within the following ranges.

Note: The above restrictions apply to the relay output load current from the CPU Unit even if Expansion I/O Units are not connected.
