The inductance is definitely the limiting factor.  Try running a single M15 
with pulling magnet selector from a 24 VDC loop supply.  The range is nil.  My 
personal experience is that you can run three 60 ma M14/15/19 pulling magnet 
selectors plus any number of nominally zero resistance/inductance units (TD, 
etc) off of a single standard 115 VDC supplied loop without serious degradation. 
 I never tried four, so I don't know.  But based on the 24 VDC experience I 
rather doubt it.

I would guess you be able to run more holding magnet selector machines (at 60 
MA) than pulling magnet ones.  But I never owned but one so equipped so I 
don't know for sure.
