hi Mark,
I have noticed for a while that the pdf's sometime will not download correctly from the Forum, also the Blog.
The way around this is to place the original pdf in a folder before zipping.
I have EDITED the previous post and the relay zip, give it a try, let me know.

One of these days I will get my head around electronics Math....Funny thing is the two coils in mention the 13ohm will run fine while the 200ohm barley wakes up.
The data on the coils says it pulls 50ma.
How does 50ma convert to ohms? I'm sure I measured the ohms on the coil wrong as its only a small coil-
**broken link removed** 12v version.??
Vasir sorry about muscling in on your thread but it may also answer some of your questions!!!

Hi Eric
The two coils are actually in series so I put a 7W 220R (closest I had) in parallel with the 243R coil and that worked a treat... is this right method??

hi Mark,
Can you confirm the working voltage of the 13R relay.?
If its 12Vdc then adding a 220R in parallel with a 240R relay coil would be approx 110R.
So the voltage across the 13R coil would only be [13/[123]] * 24 = 2.5V ! and across the 240R coil would be 21.5V. it will cook.!

So do I put a series resistor in on the 240R coil as well ?? (430R)?- (R= V/I) 21.5/0,05 ?
Cheers
Edit:
I have 2 coils both in series. 1 coil is 13 ohm and a working current of around 200ma V= I*R= 0.20*13= (2.6v)
the other coil is 240 ohm at 50ma V= I*R= 0.24*50= (12v)
My supply is 24vDC.

hi Mark,
I think a diagram would help you best, look at this image.
