I/O 10 / P55 Analog Output Span

I/O: Aout Span
10 100%
Range 1 – 125% (Default: 100%)
Description The analog output signal can be scaled using the Analog Output Span parameter. For a 0-10V output or 0-
20mA output, a 100% scaling outputs the maximum voltage (10V) or current (20mA) when the selected output
function requests 100% output. A scale of 50% outputs 50% voltage/current when the analog output function
requests a 100% output.
NOTE: For a 4-20mA output, set the Analog Output Span to 80% and the Analog Output Offset (I/O 11 /
P56) parameter to 20%.
NOTE: The output does not exceed 100% (10V or 20mA).
Example: 0% output => 4mA, 100% output => 20ma

I/O: Aout Offset
11 0%
Range 0 – 99% (Default: 0%)
Description The analog output signal can be offset using the Analog Output Offset parameter. A 50% offset outputs a 50%
output (5V in the 10V case) when 0% is commanded. If the selected variable requests 100% output, the span
should be reduced to (100 minus offset) so that a 100% output request causes a 100% output voltage (x%
(100-x)%span) =100%.
NOTE: For a 4-20mA output, set the Analog Output Span (I/O 10) to 80% and the Analog Output Offset
to 20%.
