It would be helpful to post a model and a description of how exactly you want the signals to behave. Attached is an implementation of a turn-on, turn-off, and a combined turn-on & turn-off delay:

However, some users might be imagining a “non-deterministic turn-off delay”. See [this forum post for additional discussion](https://forum.plexim.com/t/turn-off-and-turn-on-delay-implementation/281/4).
