Analog Input Units
116
The Analog Input Unit converts analog input data to digital values. The digital
values depend on the input signal ranges, as shown in the following diagrams.
When the input exceeds the specified range, the AD conversion data will be
fixed at either the lower limit or upper limit.
--10 to 10 V
The --10- to 10-V range corresponds to the hexadecimal values F448 to 0BB8
(--3000 to 3000). The entire data range is F31C to 0CE4 (--3300 to 3300). A
negative voltage is expressed as a two’s complement (16 bits). If the line is
disconnected, the data will be the same as an input of 0 V (0000 Hex).

The 0- to 10-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 disconnected, the data
will be the same as an input of 0 V (0000 Hex).

is expressed as a two’s complement (16 bits). If the line is disconnected, the data
will be the same as an input of 0 V (0000 Hex).
