#166646 - snubber Responding to: Lukas Valecky's previous message |
Thank you very much for all your replies. I only want to know if the schematic is correct to relay control...
And don't forget the snubber... Do you mean the diode in parallel with the relay coil in my schematic or the snubber at the output pins of the relay when switching inductive load? I need to control 12V door opener - for this I want to use resistor 50R and capacitor 0.1uF in series but I dont know what type is the the best - film or ceramic? Thanks... |
