What you say is true. I was driving contactor using relay, which were driven by 4N33, on isolated powersupply. My input sensor signals are alos through PC817. Adding Moc3041 reduce noise problem. But it was eliminated by higher rating transformer and I increased Filter capacitpr to 2200microfarad. Now there is no problem of interfearance, but power off should persist for atleast 4 seconds, as unreg. supply do not die easily. Also I have connected Triac and Load||RC. Thanks A lot Vimal Amin |
