Analog Input Units

0 to 5 V
The 0- 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). A negative
voltage is expressed as a two's complement (16 bits). If the line is discon-
nected, the data will be the same as an input of 0 V (0000 Hex).

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). If the input
voltage falls below 0.8 V, the open-circuit detection function will activate and
the converted data will be set to 7FFF.

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 (16 bits). If the line is discon-
nected, the data will be the same as an input of 0 mA (0000 Hex).
