4 SYSTEM CONFIGURATION
4.4 Limitation on Current Consumption
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.
In the case of AC power supply type
Calculate following the procedure below.
1.
Check the power supply capacity of the powered input/output module.
(
Page 42 Powered input/output module)
*1 Value when 24 V DC 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 the extension module.

3.
Calculate the total current consumption of each power supply.
