Power Supply Check From Extension Power Supply Module (Current Consumption Calculation) - Mitsubishi Electric MELSEC iQ-F FX6U Hardware User Manual

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.
In the case of AC power supply type
