1Input range setting (DIP) switches (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. See page 2-3 for
details.
2Analog input terminal block (9-pin)
Use a terminal block socket made by Phoenix Contact Co. (product number: 1840434).
(See FP0 Hardware Manual.)
3Power supply connector
The power supply connector (supply 24V DC) is hooked up by using the power supply
cable (AFP0581) that comes with the unit.
4Expansion connector
The expansion connector hooks up the expansion unit to the internal circuit of this unit.
(See FP0 Hardware Manual.)
5DIN rail attachment lever
The DIN rail attachment lever allows simple attachment to a DIN rail. The lever is also
used for installation on a FP0 slim type mounting plate (AFP0803).
6Expansion hook
The expansion 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 gray 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 a lot of noise.)
4) The switch reads only once when the power supply of FP0
control unit is turned on.

3.3 Averaging Function for Voltage and Current Ranges
When the averaging function is set to on, the internal processing of the A/D conversion
unit is as shown in the diagram below (in this example there are two input channels, and
the input range setting switch Nos. 3 and 4 are off).

Starting with the most recent data, the data from the last ten times is taken. The
maximum and minimum values are deleted, and the averaging is carried out on the
remaining eight items. The obtained values are output to WX2 and WX3. The values
output at this time always use the most recent averaged value (decimals are discarded).
