Open-collector 200 Kpps 24V (maximum) < 25 mA
 UY: filter width setting
If the pulse frequency is too high, causing a pulse width smaller than the filter width, then this pulse
gets filtered out as noise. Therefore, set the filter width smaller than the actual pulse width.
You should set the filter width as 4 times smaller than the actual pulse width.
