-Always take precautions to ensure the overall safety of your system, so that the whole
system remains safe in the event of failure of this product or other external factor.
-Do not use this product in areas with inflammable gas. It could lead to an explosion.
-Exposing this product to excessive heat or open flames could cause damage to the lithium
battery or other electronic parts.
CAUTION
If critical situations that could lead to user’s injury or only property damage is
assumed by mishandling of the product.
-To prevent excessive exothermic heat or smoke generation, use this product at the values
less than the maximum of the characteristics and performance that are assured in these
specifications.
-Do not dismantle or remodel the product. It could cause excessive exothermic heat or smoke
generation.
-Do not touch the terminal while turning on electricity. It could lead to an electric shock.
-Use the external devices to function the emergency stop and interlock circuit.
-Connect the wires or connectors securely.
The loose connection could cause excessive exothermic heat or smoke generation.
-Do not allow foreign matters such as liquid, flammable materials, metals to go into the inside
of the product. It could cause excessive exothermic heat or smoke generation.
-Do not undertake construction (such as connection and disconnection) while the power
supply is on. It could lead to an electric shock.

1Input range setting switch (voltage/current)
This switch is used to change the input mode (between voltage and current). All eight
input channels of the A/D converter unit operate at the same level. Refer to page 3−3
for details.
2Analog input terminal block (9-pin)
Use a terminal block socket made by Phoenix Contact Co. (product number:
1840434).
3Power supply connector
Supply 24V DC. It is connected using the power supply cable (AFP0581) that comes
with the unit.
4Expansion connector
connects an expansion unit to the internal circuit of the this unit.
5DIN rail attachment lever
allows simple attachment to a DIN rail. The lever is also used for installation on FP0
slim type mounting plate (AFP0803).
6Expansion hook
is used to secure expansion units.

Connect input instrument between V terminal and COM
terminal.
First, connect both V terminal and I terminal. And then
connect input instrument between it and COM terminal.
Notes
•Tie the COM connectors for two channels together as indicated by the
black circles (“ ”) in the diagram above so that no more than two
wires go to each COM terminal.
•The two COM terminals are connected internally.
•We recommend that you use dual−core twisted pair shielded wiring
for the analog input wiring, and that you connect the shield to earth.

Notes
•(∗1) It is possible to use the 0 to 5V range and 0 to 20mA range
together.
•(∗2) The A/D conversion data is set for the specified input contact point
area for each A/D conversion, on each channel.
•(∗3) On each channel, for each A/D conversion, the maximum and
minimum values from the data of the last ten times are excluded, and
the data from the other eight times is averaged, and the result set.
(Use when the environment contains much noise.)
•The switch reads only once when the power supply of FP0 control
unit is turned on.
