Here, analog inputs 1 and 2 use current inputs (4 to 20 mA), so pins 1 and 2
are turned ON (bottom).
Note When a voltage input is used, always turn OFF the corresponding pin of DIP
switch 1, even if the range code is set to a value other than 010 or 011.
When minute fluctuations occur in an analog input signal, average processing
can be used to stabilize the input. With average processing, the average of
the previous eight data values is used as the conversion data.

Here, average processing is used by analog input 3, so pin 3 is turned ON
(bottom).
Use the connectors provided with the Analog I/O Boards when wiring analog
I/O.
