Output ripple
Output current
Isolation
We recommend S8JX series power supplies made by OMRON for the unit power supply for Slave
Units.
Precautions for Correct Use
• The I/O power supply for the input section of the e-CON connector type Slave Units is shared
with the unit power supply. To calculate the output current of the unit power supply, be sure to
use "unit power supply current consumption" to which "input current" and "input connection
device supply current" have been added.
• Use a power supply with sufficient capacity considering the inrush current at startup.

Connecting the Unit Power Supply

Connect a cable from the 24-VDC unit power supply to the unit power supply connector on each Slave
Unit, and supply power to individual Slave Units.
Digital I/O Slave Units, Analog I/O Slave Units, and Encoder Input
Slave Units
Mount a pin terminal, or equivalent to the unit power supply cable so that it will not be displaced.
