Functional description

General

After a positive edge at the binary input xIN and a subsequent delay time tShift,

a impulse with a time duration tPT is generated at the impulse output xQ. Alternatively, impulse generation can also be triggered by the setpoint / parameter

xTest.

Time output tET

If the impulse output xQ is active, the time difference between the target duration tPT and the time duration of the impulse on

xQ is displayed. If pulse output xQ is inactive, the value T#0s is always displayed.
