Functional sequence
1. A signal change (FALSE/TRUE edge or TRUE/FALSE edge) at the
bIn
input sets the
bOut
output to TRUE.
2. After the parameterised pulse duration has elapsed, the
bOut
output is reset to FALSE
unless another signal change has taken place at the
bIn
input.
– In case of another signal change at the input
bIn
, the pulse time restarts to elapse,
i.e. the output
bOut
can be retriggered.
