Page 12: Switch-Off Delay
DP2122 Speed monitor 4.4.7 Switch-off delay The switch-off delay enables filtering of input signals. The switching delay is activated or restarted by a negative switching edge of the input signal. Only if the input signal is still inactive after the delay time has elapsed, the output wil be set to the inactive switching state. -
