Analog Input Units
Section 9-2
Analog Input Signal
Ranges
Analog input data is digitally converted according to the input signal range as
shown below.
Note
When the input exceeds the specified range, the A/D conversion data will be
fixed at either the lower limit or upper limit.

10 to 10 V Inputs
When the resolution is 1/6,000, the –10 to 10 V range corresponds to hexa-
decimal values F448 to 0BB8 (–3,000 to 3,000). The range of data that can be
converted is F31C to 0CE4 hex (–3,300 to 3,300).
A negative voltage is expressed as two’s complement.
When the resolution is 1/12,000, the –10 to 10 V range corresponds to hexa-
decimal values E890 to 1770 (–6,000 to 6,000). The entire data range is E638
to 19C8 hex (–6,600 to 6,600).
A negative voltage is expressed as a two’s complement.
