I saw Tom's post on his dust collector remote activated blast gates. I would like to have a relay in my 220v outlet to my dust collector and remote control to just turn the outlet off and on with. I'm sure there's a way I can do it with moteinos. I don't care about power drain on the receiving end (the outlet). any suggestions?
I assume that your dust collector already has a magnetic start switch, as most do for a variety of reasons. If this is the case, all you need is a relay that can handle the load of the DC's contactor coil (would be less than an Amp, I would guess). This relay NO contacts would bridge the switch contacts of the starter.
This is what I did with my DC and it works well without undue electrical noise or the need for an additional power relay.
