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.
