Standard Splitter Output (STD SPLITTER) 
This function can be used for heat/cool applications.  It is a deadband-based splitter that divides a Split 
loop’s output (-100% to +100%) into two outputs CVn A1 and CVn A2, both of which are zero when the 
loop output is zero (Figure 4-14).  A deadband provides a range of loop output within which both split 
outputs remain at zero.  For overlapped outputs, use Advanced Splitter.  Note: A third output CVnA3 is 
displayed Online and should be ignored.

Prompt 
Range/Selections 
Definition 
RANGE LOW 
RANGE HIGH 
OFF or number 
Enter the output’s display limits.  Output is not clamped or 
flashed when it exceeds these limits. 
INPUT 
OFF, analog parameter, 
number 
Input source.  Typically, this is the output value (OV) of a 
Split Output type of loop. 
FEEDBACK #1 
AOn BC, LPn BC, CVn BC 
Enter an AO, LP or CV for the back calculation value (BC) 
of the analog output assigned to the A1 output. 
FEEDBACK #2 
AOn BC, LPn BC, CVn BC 
Enter an AO, LP or CV for the back calculation value (BC) 
of the analog output assigned to the A2 output. 
OUTPUT 
DEADBAND 
OFF or number 
Deadband up to 10% of the input span.  In this range, both 
split outputs will remain at zero.
