USING THE OUTPUT
The output line can be configured to
rep
licate (follow) any of the
input lines. This allows other
pulse
-
counting or alarm
-
sensing equipment to have access to the same signals. For instance
the
CNI2
may be counting
pulses on Line
-
2
and another piece of equipment located nearby
may
need to count
these
pulses
too.
There are some limitations that you should be aware of. The processor samples each input line
at a rate defined by the
SAMPLE RATE
. It then sets the output line to the same state with each
pass. Input signals that change faster tha
n the sample rate may
not be accurately reproduced
as illustrated here.

Also, when an input signal changes state there could be a delay of up to one sample period
before the output matches that state, as illustrated
here.
