Analog Inputs

Last two channels can be used as analog inputs, but two of the analog inputs
must be the same range.

(1) When an input is not being used, short the + and – terminals.
(2) Separate wiring from power lines (AC power supply lines, high-voltage
lines, etc.)
(3) When there is noise in the power supply line, install a noise filter on the
input section and the power supply.
When the input exceeds the specified range, the AD converted data will be
fixed at either the lower limit or upper limit.
0 to 10 V
The 0 to 10 V range corresponds to the hexadecimal values 0000 to 2EE0 (0
to 12000). The entire data range is FDA8 to 3138 (−600 to 12600). A negative
voltage is expressed as a two's complement.
