DELAY


DELAY

delay

The DELAY device generates delayed signals respect to the input signal. Two kinds of functionality are available : DELAY MODE or HOLD MODE. In DELAY MODE a pulse applied on its input generates a single pulse after the programmed time. In HOLD MODE a pulse on its input activates the output for all the programmed time.

There is the possibility to condition the behavior of the device for the pulses following the first trigger pulse. Using the NO RETTRIGERABLE option the pulse following the first trigger pulse will be ignored. With the RETTRIGERABLE option set, the elapsed time will be cleared every time a rising-edge is recognized on the input so the time-past event will take place starting from the last pulse.

DELAY device, like CLOCK and DEBOUNCE , are SYSTEM TIMER dependant.

For further information see TIMING RESOLUTION .
