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.
