Current consumption calculation method
The following shows how to calculate current consumption.
The same calculation method applies to the CPU module, the powered input/output module, and the extension power supply
module.
However, the calculation method is different at the following points for the FX5S CPU module and the FX5UJ CPU module.
1.
Check the power supply capacity of the CPU module, powered input/output module, or extension power supply module
being used.
Ex.
For the FX5U CPU module
Ex.
For the FX5UJ CPU module
For the FX5UJ CPU module, calculation of the current consumption of the 5VDC power supply is not required.
*1 Value when 24VDC service power supply is used for input circuits. The power supply capacity differs when external power supply is
used for input circuit.
2.
Check the current consumption of extension devices.
Ex.
For the FX5U CPU module
*1 When using an external power supply for an input circuit, calculate current consumption of the 24VDC power supply as 0mA.
Total current consumption
• 5VDC power supply: 510mA
• 24VDC power supply: 240mA
Module
Difference
FX5S CPU module
Calculation of the current consumption of expansion adapters and expansion boards is not required. When using the
expansion adapters that require an external 24VDC power supply, prepare the external power supply.
FX5UJ CPU module
Calculation of the current consumption of the 5VDC power supply is not required.
When supplying the power from a 24VCD service power supply to the expansion adapters (FX5-4DA-ADP, FX5-4A-
ADP) that require an external 24V power supply, calculation of the current consumption is required.
For extension modules, calculation of current consumption is not required when the total number of occupied I/O points
is within 32 and the number of extension modules is 2 or less. For extension modules connected after the limits are
exceeded, 200mA produced by the 24VDC power supply is consumed per module.
