Hello all!
I have done a control circuit that needs to operate two contactors (with 240v ac coil). I'm experiencing interference on the circuit, the LCD goes mad when installed. And after some research I found that maybe, using an RC Snubber circuit on each coil would resolve the problem...
If the RC Snubber is the way to go, now I need to select the components. Some people say that 220 Ohm resistor and a 0.5µF are good values for a 240v AC coil, what do you think? And since I can not measure the power consumption of the coil right now, what would be the power required for the resistor?
Thank you!
