Analog Input Signal Ranges
Analog input data is digitally converted according to the input signal range as shown below.
Additional Information
When the input exceeds the specified range, the A/D conversion 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 comple-
ment.
1 to 5 V
The 1 to 5 V range corresponds to the hexadecimal values 0000 to 2EE0 (0 to 12000). The entire
data range is FDA8 to 3138 (
−
600 to 12600). Inputs between 0.8 and 1 V are expressed as two’s
complements. If the input falls below 0.8 V, open-circuit detection will activate and converted data
will be 8000.
