Recommended Compact DC Power Supply (OMRON)
* The maximum power consumption of the Controller is 20 W (i.e., 0.8 A at 24 VDC). The inrush cur-
rent, however, must be considered when selecting the power supply capacity. A power supply with an
output of 1.1 A min. at 24 VDC is recommended.
Correct Use
• If the Antenna and power supply are too close, some noise generated from the power supply may
interfere with communication. Make sure that there is a distance of 1 m or more between the Antenna
and power supply.
• If the Controller and Antenna are too close, the Controller may interfere with the communication
between the Antenna and ID Tag. Make sure that there is a distance of 80 cm or more between the
Controller and Antenna.
Note
• Provide 24 VDC to the Controller. The allowable fluctuation of the power supply is between 20.4 and
26.4 VDC (i.e., 24 VDC
−
15%/+10%). Make sure that the power supply voltage is within this range.
• The maximum power consumption of the Controller in the largest configuration is 20 W. An inrush
current of approximately 30 A at 24 VDC, however, flows when the Controller is turned ON. Take this
into consideration when preparing the power supply.
• Provide a power wire with a thickness of at least AWG18 to prevent voltage drops. Twisted-pair wire
is recommended for the power line.
• Ground the Controller at a resistance of 100
Ω
or less to protect the Controller from noise interfer-
ence. The thickness of the ground wire must be at least AWG18.
