15-2 Analog Input and Output Signal Ranges
Analog I/O data is digitally converted according to the analog I/O signal range as shown below.
Note When the input exceeds the specified range, the AD converted data will be fixed at either the lower limit or
upper limit.
 -10 to 10 V Input
When the resolution is set to 1/6,000, the -10 to 10-V range corresponds to hexadecimal values
F448 to 0BB8 (-3,000 to 3,000). The entire data range is F31C to 0CE4 (-3,300 to 3,300).
A negative voltage is expressed as a two’s complement.
 0 to 10 V Input
When the resolution is set to 1/6,000, the 0 to 10-V range corresponds to hexadecimal values 0000
to 1770 (0 to 6,000). The entire data range is FED4 to 189C (-300 to 6,300).
A negative voltage is expressed as a two’s complement.
