Notes for wiring
IMPORTANT
•
Do not connect the lead wires for
temperature and humidity outputs to the
power supply lines.
Doing so may cause smoke, burnout, or
device failure. Make sure all the wires
are correctly connected before supplying
power
•
Do not share the 24 V AC transformer
with other products.
For power supply wiring and temperature/humidity
output wiring, 1.25 mm
2
or greater shielded multi-
core cables (CVV-S) are recommended.
1.25 mm
2
or greater IV cable is also connectable.
Be sure to ground the shielding on the controller
side.
The maximum cable length is 100 m.
For the wiring length, refer to the Specifications/
Instructions of the controllers to which the sensor is
connected.

DC power supply
IMPORTANT
•
24 V DC power supply can be shared.
However, wire the brown wire (+) , blue
wire (+) , black wire (-) , and gray wire
(-) as illustrated in Fig. 17.

IMPORTANT
•
The AC transformer (24 V AC) cannot be
shared.
The same number of AC transformers (24
V AC power supply) as the sensors are
required.
