The maximum power consumption of the Controller is 20 W (i.e., 0.8 A at
24 VDC). An inrush current, however, will flow when the Controller is turned ON.
Take this into consideration when preparing the power supply. A power supply
with an output of 1.1 A min. at 24 VDC is recommended.
Note
1. If the Antenna and power supply are too close, some noise generated from
the power supply may interfere the communications of the Antenna. Make
sure that there is a distance of 1 m or more between the Antenna and power
supply.
2. If the Controller and Antenna are too close, the Controller may interfere with
the communications between the Antenna and ID Tag. Make sure that there
is a distance of 80 cm or more between the Controller and Antenna.
3. Provide 24 VDC to the Controller. The permissible variation of the power
supply is between 20.4 and 26.4 VDC (i.e., 24 VDC
–15%
/
+10%
). Make sure
that the supply voltage is within this range.
4. The maximum power consumption of the Controller is 20 W. An inrush cur-
rent of approximately 30 A at 24 VDC, however, flows when the Controller is
turned ON. Take this into consideration when preparing the power supply.
5. Provide a power wire with a thickness of at least AWG18 in order to prevent
the dropping of voltage. It is recommended that twisted-pair wire be used for
the power line.
6. Ground the Controller at a resistance of less than 100
Ω
to protect the Con-
troller from noise interference. The thickness of the ground wire must be at
least AWG18. If two or more Controllers are connected to one another in
synchronous operation, be sure to ground the Controller located at either
end of the system at a resistance of less than 100
Ω
and connect the ground
terminals of other Controllers with the shielded wire of the synchronous
cable. If the Controller is not ground properly, it may not operate.
•
Use the provided ferrite core for the suppression of noise generation as shown
below.
1, 2, 3...
1. Wire the power supply and ground wires.
2. Wind the power supply and ground wires together around the ferrite core
once so that the ferrite core will not move as shown below. The ferrite core
must be located within 10 cm of the Controller.
