Remote Controlled Switch Board Issue
See attached circuit.
This is the circuit which I designed.
The issue is there is no common GND between VSINE (220V Neutral) and 5V circuit GND.
I am using Hi-Link 5V 3W SMPS module to get power for circuit.
Will the ZCD circuit work?
I want to turn On/Off SSRs at ZC and so I have used the ZCD circuit. ZCD circuit input is from LINE.
In simulation if I connect NEUTRAL to chassis connector (I guess GND and Chassis are both 0V in Proteus) then circuit works but in real hardware connecting NEUTRAL to 5V circuit GND is wrong.
