Power Supply Capacity of System
This section describes how to calculate the total current consumption value and voltage drop value in order to
determine the power supply capacity (capacity of 24V DC power supply unit).
Calculation of Total Current Consumption Value
To determine the total current consumption, check the current consumption of each I/O unit.
Calculate the power supply capacity while referring to the list of current consumption values shown below.

CAUTION
Use of a longer cable will cause more voltage drop. If the voltage drops below the rated voltage, the
I/O units will not work. In this case, use the local power supply unit.
Elongation of the transmission distance will cause more voltage drop
at the line end (between +24V and 0V).
Voltage drop (V) = Cable length (m) × 2 × conductor resistance (Ω/m) × current (A)

Power Supply Capacity of System
Necessity of Local Power Supply Unit
The 24V DC power supply unit that drives the system uses either the centralized power supply method (use of
only one power supply unit) or the decentralized power supply method (use of additional local power supply unit)
to supply power to each unit.
At rst, calculate the total current consumption value (sum total of current consumption values of all units ‘+’ sum
total of load current values of I/O devices).
After that, from the obtained calculation result, cable length, and conductor resistance, calculate the voltage
drop value, and determine the voltage to be supplied to each unit.
If the voltage supplied to each unit is above the rated voltage (22.8V or more for the controller, 21.6V or more for
the I/O unit), you can design the system using the centralized power supply method.
If the voltage supplied to a unit is out of the rated voltage range, connect a local power supply unit, and use the
local power supply method.
Designing of system using local power supply method
Chapter 1
CAUTION
To use a local power supply unit, turn on the local power supply unit rst, and then turn on the main
power supply unit, or turn on these power supply units at the same time.
If the main power supply unit is turned on rst, the system may not operate properly.
In the following cases, connect a local power supply unit:
● The communication distance is too long, and voltage drop is too large.
For this reason, it is not possible to supply the rated voltage to the I/O units.
● A 2-core cable is used for connection of the I/O unit (for the D-G line only).
● The main power supply unit and the local power supply unit should be the small capacity type.
● An I/O device that generates a large noise should be used.
Notes: 1) The conductor resistance values shown in the above table are reference values.
To determine the conductor resistance values for the actual cables, contact the cable manufacturer.
2) The conductor cross section of the exclusive 4-core at cable should be 0.5mm2.
To determine whether a local power supply unit is necessary, refer to the owchart shown on the next page.
