There is a way to limit piston activation times using current limiters.

Basically... have the input go into a repeater which will power a block, then wire the power from the block into the piston that you want to limit.

From there, bring another current from the input into a NOT gate. That current should go into a repeater. From there, the current ought to go into a sticky piston that, when extended/powered, should connect with the powered block mentioned before.

Adjust the tick settings on the repeater placed after the NOT gate to adjust how long you want the piston to be extended for when powered.

I hope this helped. :3
