[GreenKeys] Loop Supply

[Ralph Mowery]

I thought the holding type magnets could be paralleled for 60 ma and series
for 20 or 30 ma but the pulling types (larger coils) were series for 60 ma
only.

 

Even with that is there exactly 60 ma loop current, or just an estiment ?

I'm foggy about the specifics of the 15 (about 57 years of cobwebs), but you
show in your drawing what appears to be magnets wired in series instead of
parallel, which would be normal for 60ma.  You can go 30ma with parallel
connection, normal was 20.
