1 to 5 V
The 1 to 5 V range corresponds to the hexadecimal values 0000 to 1770 (0 to
6000). The entire data range is FED4 to 189C (−300 to 6300). 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.

0 to 20 mA
The 0 to 20 mA range corresponds to the hexadecimal values 0000 to 1770 (0
to 6000). The entire data range is FED4 to 189C (−300 to 6300). A negative
voltage is expressed as a two's complement.

4 to 20 mA
The 4 to 20 mA range corresponds to the hexadecimal values 0000 to 1770 (0
to 6000). The entire data range is FED4 to 189C (−300 to 6300). 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.
