Note
:
If the label on your AC I/O module
does not
indicate 120/240V,
your module is designed for use
only
with 120V. Additionally,
all AC wiring must be shielded.
AC Discrete Inputs
You can configure each channel as an AC input/detector. Each
channel can detect the presence of an AC signal between 90 and 265
Vrms at 47 to 63 Hz. In discrete input mode the module monitors the
status of various AC sources.
You can also software-configure each channel to function as a latched
DI, which remains in active state until reset. Other parameters can invert
the field signal and gather statistical information on the number of
transitions and the time accumulated in the on or off state. The fastest
time that each channel within the module can be read is 20 times per
second. See
Figure 3-18.
