DESCRIPTION:
Use these screens (Digital Aux. Output A
- J) to setup and control an Auxiliary Digital Output using
the signal from an Analog Input. The following descrip-
tions apply to all Digital Aux. Output pages.
The graphic below illustrates one scenario in which an
analog Temperature input is used to drive a digital output.
When the temperature exceeds the On When value of 75°,
the output will energize. It will remain in this state until
the analog input falls below the Off When value of 73°.
This state will persist until the input again exceeds the
On When value. The resulting temperature control would
resemble the following sine wave:
75°
74
°
73°
76°
72°
Output is
energized
Output is
de-energized
