Power Supply Types and Applications
This section describes the power supply types and applications for the IO-Link I/O Hubs.
Power Supply Types
There are the following two types of power supplies that supply power to the IO-Link I/O Hubs.
Power supply
type
Description
Unit/input power
supply
The Unit/input power supply provides power to the IO-Link I/O Hub for operation and inter-
face with input devices.
The power is supplied from the IO-Link Master Unit through the IO-Link cable to an IO-Link
I/O Hub.
Output power
supply
The output power supply provides power to the Digital I/O Variable Hub for interface with
output devices.
The power is supplied from the IO-Link Master Unit through the IO-Link cable to the Digital
I/O Variable Hub.
Power Supply Applications
The applications of the power supplies are given below.
Power supply type
Description
Unit/input power supply
•
Operation of the internal circuits and input circuits of an IO-Link I/O Hub
•
Power supply to input devices connected to an IO-Link I/O Hub
•
Input current from input devices connected to an IO-Link I/O Hub
Output power supply
•
Drive of the output circuits of an IO-Link I/O Hub
•
Operation of the output devices connected to an IO-Link I/O Hub

Power Supply System
The power supply system for the IO-Link I/O Hubs is given below.
The Unit/input power and output power are supplied from the IO-Link Master Unit, which is connected
to an external power supply, through the IO-Link cable to the IO-Link I/O Hub.
When the output power supplied to the Digital I/O Variable Hub, you must configure and operate the
IO-Link Master Unit as shown below. The following configuration and operation supply the output pow-
er to the Digital I/O Variable Hub.
• Port setting
Set pin 2 of the port of the IO-Link Master Unit, which is connected to the Digital I/O Variable Hub, to
SIO (DO) Mode.
