Module Resolution
Since the module has 12-bit resolution, the analog signal is converted into 4096 counts
ranging from 0–4095 (2
12
). For example, with a 0–10V range, send a 0 to get a 0V signal, and
send 4095 to get a 10V signal. This is equivalent to a binary value of 0000 0000 0000 to 1111
1111 1111, or 000 to FFF hexadecimal.
Each count can also be expressed in terms of the signal level by using the following equation.
The following table shows the smallest change in signal level due to a digital value change of
1 LSB count.
