Limitation On Current Consumption; Power Supply Check From The Cpu Module (Current Consumption Calculation) - Mitsubishi MELSEC iQ-F series User Manual

4.4

Limitation on Current Consumption

Power required for expansion adapters and extension modules is supplied from the CPU module, powered input/output
module or extension power supply module. The number of extension devices that can be connected must be determined from
the capacity of the power supply.
Power supply check from the CPU module (current consumption
calculation)
Check if power can be supplied to extension devices with the power supply capacity of the CPU module.
Ex.
Expansion
CPU module
adapter
Power supply from the CPU module
Calculate following the procedure below.
1.
Check the power supply capacity of the CPU module used.
