A-5 Expansion Specifications of External
Power Supply
When using the external power supply for AC-power-supply CPU Units, the external power supply for
the 30-point and 40-point AC-power-supply CPU Units (CP1E--A) can be used beyond
300mA within the capacity range of the power supply built in the CPU Units.
Calculate the usable capacity of external power supply according to the following example.
