*4.
For example, for the Digital I/O Variable Hub, confirm that the output power supply voltage is 20.4 to 26.4
VDC.

Calculating the Total Current Consumption
The calculation methods for the total current consumption of the Digital I/O Hub from the Unit/input
power supply and output power supply are given below.
Total Current Consumption from Unit/Input Power Supply
= (Current consumption from Unit/input power supply) + (Current consumed between the Digital I/O
Hub and input devices)
The items of the formula are described below.
Item
Description
Current consumption from
Unit/input power supply
Current consumed by the Digital I/O Hub. Use the value of
current
consumption from Unit/input power supply
specified in
Current consumed between
the Digital I/O Hub and input
devices
Use the following formula to calculate this value.
(Sum of the currents consumed by the input devices) + (Input current to the
*1.
This corresponds to the
Input current
of
Digital input
specified in
2-1-2 Individual Specifications
Total Current Consumption from Output Power Supply
= (Current consumption from output power supply) + (Current consumed between the Digital I/O
Hub and output devices)
The items of the formula are described below.
Current consumption item
Description
Current consumption from output
power supply
Current consumed by the Digital I/O Hub. Use the value of
current
consumption from output power supply
Current consumed between the Digi-
tal I/O Hub and output devices
Use the following formula to calculate this value.
(Load current × Number of outputs used)
Calculation Example for the Total Current Consumption
A calculation example of the total current consumption for the Digital I/O Variable Hub of the Digital I/O
Hubs is given below.
Application Conditions for Connected External Devices
The conditions for the Digital I/O Variable Hub and connected external devices are as follows:
