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
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
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.
