GENERAL
The FP1P is a compact, front terminal connection type pulse
repeater that converts pulses from voltage-free contacts, open
collector contacts, voltage pulses, and current pulses into isolated
transistor switch pulses.

1. MOUNTING METHOD
1.1 Installing/Uninstalling the Mounting Block
The mounting block is necessary for rack mounting or wall
mounting.
Installing the mounting block
zFit the mounting block into the grooves of the converter, and
slide it in the direction of an arrow as shown below-left.
Uninstalling the mounting block
zLift the stopper using a slotted screw-driver as shown be-
low-right, and pull the mounting block to remove it.

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 satises 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).

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 specied performance.
