Analog I/O Units
Section 7-4
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.
