2. Rule when using power adapter or dedicated power supplies
When the capacity of the built-in power supply is insufficient, use the power supply adapter or dedicated
power supply in accordance with the system configuration. (The power supply adapter and dedicated power
supply can be used together.)
When using the power supply adapter or dedicated power supply, calculate "current consumption", "voltage
drop" and "minimum operating voltage (20.4V DC)" for each power supply adapter, and satisfy each condition
in the system configuration.
→
For the power supply adapter and dedicated power supply, refer to the manual of the
corresponding product.
System configuration examples
1) Current consumption calculation
2) Start-up current calculation
3) Voltage drop calculation
4) Confirmation related to the minimum operating voltage (20.4V DC) of the module
*1. When using remote I/O stations that receive power for connected I/O equipment from the built-in
power supply, power supply adapter or dedicated power supply, include the current consumption of
the connected I/O equipment.
