This file I attached is already edited.Hi sir,
Thank u for ur idea can u send me the circuit edited with the 120v to 240v Ac please . . . . . ? ? ? ? ? ? ? ? ? ? ? ??
And some are only rated for 12V or more commonly 28 VDC. The ratings are there to indicate that the contacts open fast enough and end up far away from each other that arcing won't occur. You might be able to operate a 240V device with a 120V contact rated relay but I certainly wouldn't try it with a low voltage contact rated one.To answer this question correctly you need to provide the part number (or datashet) for the relay you used.
Some relays have contact ratings up to 240VAC but many do not and only allow 120V on the contact side.
