I have a 24 VAC Contactor that I want to drive with a microcontroller through a photmos. How do I calculate the proper size resistor and capacitor for a snubber circuit? Here are some of the specifics. Thank you for your help!
Microcontroller - 5V DC 40 mA max on the output pin.
AQV252G Photomos http://www.futureelectronics.com/en/technologies/electromechanical/relays/solid-state-relays/Pages/9530346-AQV252G.aspx?IM=0
Transformer Data - 24 VAC 40 VA Transformer
Contactor Data
Contactor Nominal Coil Voltage 24
Maximum Pickup Volts 18
Drop-Out Volts Range 6 - 15
Nominal Inrush VA @ 60 Hz 20
Nominal Sealed VA @ 60 Hz 5.25
Nominal DC Resistance - Ohms ± 10% 16.5
