Here is the capture I need. Please see the below:Here's my take on a zero crossing circuit that can meet the timing requirements while minimizing power without using a transformer.
It uses a capacitive voltage divider (C1 and C2) to losslessly reduce the voltage and rectifies that to get ≈6v to 14V DC to operate a LM393 zero crossing detector that drives the opto coupler.
C2 is a film or ceramic capacitor rated for at least 500V.
C1 and C3 should be rated for at least 20V.
Capacitor C1 becomes slight reversed biased on the negative half-cycle as determined by the clamp diode D2 but that voltage isn't high enough to damage the capacitor if it's electrolytic (which can generally tolerate up to 1.5V reverse bias).
The LTspice simulation shows the opto output zero crossing rise-time occurs within <30μs of the input zero crossing (top plot).
The main power consuming component is R3 which should have a 1W or greater rating.
The 1GΩ to ground (R5) at the output is just for simulation purposes. In the real circuit there would be no deliberate connection between the main's ground and the output ground.

This is the zoom out graph when input line voltage (sine wave,yellow) crosses zero, the relay( blue ) crosses 1 voltage.
This is the zoom in graph, you can see delay time
Is this circuit to realize this function, isn't it?
