Please inquire about the availability of analog input cable and terminal block board when
you purchase the product.
3.2.3 Analog Signal Wiring
To reduce the influence of noise, crosstalk, etc., analog signal is applied to differential signal
connection. Make cables with the following specifications.

Set AINP and AINN to Twisted Paired.

The core wires use thick strands if possible.

Cable length should be less than 1m and cable as short as possible.

Make sure that there are no unused wires in the cable. Connect unused signals to ground.

Use shielded cables to shield the wires.
