If the ambient temperature exceeds 40, use the extension power supply module at the following current
values within the derating range.
Derating curve
Output current [mA]
1200
800
625
400
2.
Check the current consumption of extension devices.

3.
Calculate the total current consumption of each power supply.
Ex.
Power supply type
5 V DC power supply
24 V DC power supply
4.
Check if expansion to the extension power supply module is permitted.

If the calculation result is a negative value, the current consumption exceeds the power supply capacity of the extension
power supply module.
Reconfigure the system, adding extension power supply modules.
