How to Turn an Input ON and OFF
An input is turned on by pulling the input pin to 24 Volt common. When the input is not pulled to 24 Volt
common, it is OFF. Consult the appropriate ULTRA Plus or IQ-Series Installation Manual (1398-5.1, Part
Number 0013-1027-004 or Part Number 0013-1022-004) for voltage and current specifications of the inputs.
What Does Turning ON and OFF an Output Do?
When an output is turned ON by the ULTRA Plus or IQ, the ULTRA Plus or IQ pulls that output pin to 24
Volt common. When and output is turned OFF, the pin is left to float. Consult the appropriate ULTRA Plus or
IQ-Series Installation Manual for voltage and current specifications of the outputs.

functions that may be assigned to them. In addition inputs that are used as program select lines also may be
used simultaneously as general purpose inputs. Inputs can be used as the condition for any conditional
