Note
•
Use 24 VDC to supply power to the Reader/Writer. When you use the
recommended power supply, S82K-03024, and a cable with a thickness
of AWG16, the cable can be extended to 7 meters at maximum.If a longer
power wire is desirable, use a power supply with remote sensing function.
•
The maximum power consumption of the Reader/Writer is 25 W. An in-
rush current of approximately 30 A at 24 VDC, however, flows when the
Reader/Writer is turned ON. Take this into consideration when preparing
the power supply.
•
Provide a power wire with a thickness of AWG16 in order to prevent the
dropping of voltage. It is recommended that twisted-pair wire be used for
the power line. The thickness of AWG16 is the maximum wire diameter
that can be used with the power connector of the Reader/Writer.
•
Use Class D grounding (previous Class 3 grounding) for the
Reader/Writer for improved noise resistance.
WARNING Be sure to connect to a power supply with a maximum power supply ca-
pacity of 24V 4.2A (100W) or less.In case a short-circuit failure should
occur within the Reader/Writer, a burnout in the power cable may result.
