Digital Filter Setting Time
Set the digital filter time to 0 – 20 (00h - 14h).
Setting the digital filter time to 0 disables the function of filtering (0 is set as default and upon turning
on the power).

The following lists the relation between digital filter time and setting data.

CAUTION
The digital filter applies to all input channels; it cannot apply to only specific input pins.
To pass input signal without fail, the pulse width should be twice or larger than setting filter
time.
A digital filter doesnt work effectively if the filter time i s set (setting data: 1-10) shorter than
the opto-coupler response time.
The signal level remains the same over
the digital filter setting time, the digital filter
recognizes that signals as normal and
changes the filter output signal level.
