240v relay question - Electronic Circuits Projects Diagrams Free

767pilot · 26th February 2007, 08:29 PM

I want to do a simple test, just make sure the relay can energise
It is 240v ac coil so is it just a case of applying the live and neutral across the coil and it will energise or is there something else I need to add with it being mains voltage

thanks

If you are in the US, either live wire is 120V to neutral. To get 240V you need to use the 2 hot wires ( L1 & L2 ) like a dryer or oven.

If you are not in the US, and the normal supply is 220V~240VAC, then YES, you simply connect L and N to A1 and A2 respectively

hi pilot,

As your 'Location:' is in the UK, just use the local 240Vac mains supply.

As you dont know the 'history' of the relay, use a 3A fused plug, just in case its faulty.

You could also connect it in series with a 100W light bulb just to be on the safe side, though I personally wouldn't bother.
