Background:
Building a control box for use between a g0602 converted cnc lathe with steppers, and mini-mill with steppers.
Building it with 48vdc 13a linear power supply, 3 KL-5056D drivers, 5vdc power supply, 20a rocker switch for on/off, and will wire in a couple of 120v outlets to power the mill/lathe (obviously only one at a time) and a coolant pump (so only one outlet is needed and it will shut them off if e-stop is used).
Looks like most e-stop buttons are rated only for 10a, and plan on running closer to 15-20a with the machine, drivers, pump all running, so it looks like I need to run a relay with something like a 24vdc coil (prefer 48vdc since I already have the power supply), and I have several, but most seem to only capable of 10a at 110/120vac.
I have contactors that are rated for the amps, but the coil is 110vac which again will carry more amps than the e-stop is rated for.
So, what are some options out there for me?
