Power supply check from extension power supply module 
(current consumption calculation)
If 5 V DC power supply of the CPU module is insufficient and cannot be extended, add an extension power supply module.
Check if power can be supplied to extension modules with the power supply capacity of the extension power supply module.
Calculate following the procedure below.
1.
Check the power supply capacity of the extension power supply module used.
If the ambient temperature exceeds 40, use the extension power supply module at the following current 
values within the derating range.
2.
Check the number of input/output points and current consumption of the extension module.
*1 24 V DC power supply is supplied from the CPU module or powered input/output module.
