Power Supply Check From The Powered Input/Output Module (Current Consumption Calculation) - Mitsubishi MELSEC iQ-F series User Manual

Power supply check from the powered input/output module
(current consumption calculation)
If 5 V DC and 24 V DC power supplies of the CPU module are insufficient and system cannot be extended, add a powered
input/output module.
Check if power can be supplied to extension modules with the power supply capacity of the powered input/output module.
