Analog Input Signal
Ranges
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.
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.
4 to 20 mA
The 4 to 20 mA 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 3.2 and 4 mA are expressed as two’s complements. If the input falls
below 3.2 mA, open-circuit detection will activate and converted data will be
8000.
