1.4 DIN Rail Mounting
Place the converter so that the DIN rail ts into the upper part of
the DIN-rail groove at the rear of the converter, and push until it
clicks. The converter is xed by a slide lock (at the lower part on
the rear side of the converter).
To remove the converter, pull down the slide lock using a slotted
screw-driver.

2. INSTALLATION LOCATION
zAvoid the following environments for installation locations:
Areas with vibration, corrosive gases, dust, water, oil, solvents,
direct sunlight, radiation, a strong electric eld, and/or a strong
magnetic eld, altitude of more than 2000m above sea level.
zIf there is any risk of a surge being induced into the power line
and/or signal lines due to lightning or other factors, a dedicated
lightning arrester should be used as protection for both this
converter and a eld-installed device.
zOperating temperature/humidity range: 0 to 50ºC/5 to 90%RH
(no condensation)
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.
zRecommended cables: A nominal cross-sectional area of 0.5
mm2 or thicker for signal cables, and that of 1.25 mm2or thicker
for power cables.

Power Supply and Isolation
Power supply voltage: 24 V DC ±10% (percentage ripple: less
than 5% p-p)
Current consumption:24V DC 60 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 THE LOAD RESISTANCE FOR
CURRENT PULSES AND THE INPUT FILTER
If the signal from the generator is a current pulse, it needs to be
converted into voltage using load resistance for current pulses.
Further, if the input contains chattering noise and the like, you can
set an input lter to suppress its effect.
zThe load resistance and lter are set using a DIP switch (SW1)
inside the product.
4.1 SETTING THE LOAD RESISTANCE
Set the load resistance so that the relationship between the peak
current i (p-p) from the generator and the combined load resis-
tance RL satises the following: swing width i × RL ≥ 3V.
EL
EH
24 V or less
(peak value)
EH – EL = 3 V or more
(swing width)
0V
Set the resistance by turning on or off the DIP switch (SW1-2,
SW1-3, SW1-4).
When the SW1 settings are all off

zIf the input lter is set to ON, the input frequency will be limited
to no more than 100 Hz and the pulse width to no less than 3
ms.
5. MAINTENANCE
The product starts running immediately when the power is turned
on; however, it needs 10 to 15 minutes of warm-up before it
meets the specied performance.
