2 Check the current capacity of the 24V DC service power supply based on the
value shown in the quick reference matrix.
1. In case of AC power supply/DC input type
The remaining power supply capacity (current) can be used as a power supply to loads (sensors or the like).
When special adapters and special function units/blocks are connected by external wiring, it is necessary to
consider whether they can be covered by the remaining power supply capacity.
2. In case of DC power supply/DC input type
24V DC service power supply is not provided.
3. In case of AC power supply/AC input type
24V DC service power supply is not provided.
3 When the power supply capacity is insufficient, connect another input/output
powered extension unit.
When two input/output powered extension units or more are connected, calculate the power supply
capacities of the input/output extension blocks and special function units/blocks connected to them,
and check the capacity.
