Analog Output Span I/O 22
LCD Display
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.
z
NOTE: For a 4-20mA output, set the Analog Output Span to 80% and the Analog Output Offset to 20%.
z
NOTE: The output does not exceed 100% (10V or 20mA).
Example: 0% output => 4mA, 100% output => 20ma
See Also Analog Output Offset parameter (I/O23) on page 118.
