P61 Analog Output Span I/O 14
LED Display 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: The DIP switch (SW1) on the card changes the analog input and analog output between 0-10V or
0-20mA. See Figure 18 to see DIP Switch Settings. ANALOG INPUT SW1-1 ANALOG OUTPUT SW1-2.
z NOTE: For a 4-20mA output, set the Analog Output Span to 80% and the Analog Output Offset (P62 / I/O
15) parameter to 20%.
z NOTE: The output does not exceed 100% (10V or 20mA).
Example: 0% output => 4mA, 100% output => 20ma

P62 Analog Output Offset I/O 15
LED Display LCD Display
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%
offset + (100-x)%span)=100%.
z NOTE: The DIP switch (SW1) on the card changes the analog input and analog output between 0-10V or
0-20mA. See Figure 18 to see DIP Switch Settings. ANALOG INPUT SW1-1 ANALOG OUTPUT SW1-2.
z NOTE: For a 4-20mA output, set the Analog Output Span (P61 / I/O 14) to 80% and the Analog Output
Offset to 20%.
