3. EXTERNAL WIRING
WARNING
Be sure to turn OFF the power supply before wiring to
avoid the risk of electric shock. Use a tester or similar
device to ensure that no power is being supplied to a
cable to be connected
.
M4 screw terminals are provided for the connection of external
signals. Attach a crimp-on lug to each wire for connection to the
terminals.
●Recommended cables: A nominal cross-sectional area of 0.5
mm2 or thicker for signal cables, and that of 1.25 mm2 or thicker
for power cables.
Wiring Diagram
NOTE
●Do not connect anything to the terminals that are not
used in the wiring diagram. Otherwise it may cause
the malfunction or damage.
●The power line and input/output signal lines should
be installed away from noise-generating sources.
Otherwise accuracy cannot be guaranteed.
●Adhere strictly to the specications to avoid
overheating or damage. Before turning on the power,
ensure the following:
(a) Power supply voltage and input signal value
applied to the product should meet the required
specications.
(b) The external wiring to the terminals are as
specications.
●Do not operate the product in the presence of
ammable or explosive gases or vapors.
●The product is sensitive to static electricity; exercise
care in handling. Before you operate the product,
touch a nearby metal part to discharge static
electricity.
Power Supply and Isolation
Power supply voltage: 24 V DC ±10% (percentage ripple: less
than 5% p-p)
Current consumption: FA5A 100 mA, FA5V 90 mA
Insulation resistance: 100 MΩ at 500 V DC between input and
output, output and power supply, and input and
power supply.
Withstand voltage: 1500 V AC/min. between input and (output
and power supply)
500 V AC/min. between output and power supply.
4. SETTING PARAMETERS
