Delay Times for Inputs and
Outputs The time from an input physically energizing to the
time Pico actually reads the input is called the
input delay time, and can be set in Pico.
This function is useful, for example, to ensure a
clean input signal despite contact bounce.
Pico DC and Pico AC units function with different
input voltages and therefore have different
evaluation methods and delay times.
Delay Times for Pico DC Units (1760-L12BWB-xx, 1760-L12DWD
and 1760-L18BWB-EX)
The debounce delay time for DC signals is 20 ms.
