5 Installation and Wiring
Three-wire sensor
PNP type
The power +(V) to pin 1 is supplied from the IO-Link Master Unit through the IO-Link cable to the Digi-
tal I/O Hub.
Wiring Example for an Output Device
A wiring example for output device to an output of the Digital I/O Hub is given below.
In this example, pin 4 of port 1 serves as an output.
L
Output device
The output power that provides load current is supplied from the IO-Link Master Unit through the IO-
Link cable to the Digital I/O Hub.
Precautions for Correct Use
If you use a inductive load (solenoid valve, etc.), use a device with built-in diodes for absorbing
counter-electromotive force, or externally install the diodes. Refer to A-3 Wiring Precautions for
External Output Signal Lines on page A-5 for details.
Wiring Examples with a Branch Connector
Wiring examples of using a branch connector to connect two or more external devices to a port are
shown below.
Use the following branch connector.
• XS5R-D426-1 (OMRON)
Refer to Branch Connector for I/O Connectors on page 5-17 in 5-4-2 I/O Cables on page 5-16 for
details on the branch connector.
 Wiring Example for a Two-wire Sensor and Three-wire Sensor
In this example, pin 4 and pin 2 of port 1 serve as inputs.
