couple of questions if you dont mind
-could you replace the large coil with two more relays just connected through the coil connections
YES.
-if yes would a huge bank of relays do the job for higher voltages
Yes, but a single contact can only handle so much "spark" and the higher
voltage makes this worse. You could, however, simply use more contacts, and
the factory relays with NC contacts are far superior to the adapted RS275-0001
reason i ask is the relays appear to be cheaper at the mo than buying copper wire plus im still rubbish at winding coils
In general, you have the right idea. Always apply OHM'S LAW to keep the ratios close.
For series circuits, it seems 4 ohms per volt is good. (89ohm/24V) while the relay is
actually rated 12v @ 89 Ohm, our short (on/off) duty cycle allows 24 volts easily. I
have learned so much about how the mechanical relay reacts, I should make a
new post with my "findings" (I'm sure others have found this too).
You are on the right track rgbargee!
