Description The analog input can be scaled using the Analog Input Span parameter.
Examples:
For a 0-10V input or 0-20mA input, a 100% Analog Input Span setting results in a 0% input reading
with a 0V input and a 100% input reading with a 10V input.
For a 0-5V input, a 50% Analog Input Span setting results in a 0% input reading with a 0V input and
a 100% input reading with a 5V input.
For a 4-20mA input, a 80% Analog Input Span setting and a 20% Analog Input Offset setting results
in a 0% input reading at 4mA and a 100% input reading at 20mA.
NOTE: Input signal readings are clamped at a 100% maximum.
