240v remote controls

[Ron Hampe]

I'm looking for a minimum 30A remote control for my BlackBox Hurricane vacuum. This is located in a separate bay and provides vacuum to hold the material down to the spoil board on my cnc.

Any suggestions?

Thanks

[Russell Hayes]

Have you considered a 240v contactor switch actuated by 120v with a 120v remote?

[Maurice Mcmurry]

I salvaged a 30 amp 240 volt relay off of an air conditioner condensing unit for my dust collector. It is controlled by 24 volts. The 24 volt circuit turns on and off with a pull chain switch. I have a daisy chain of string to pull the chain from several locations. It is sort of goofy. Eventually each blast gate will have a switch.

The best way to go is to "roll your own" using an appropriately rated contactor on the 240v side for amperage and either 120v or low voltage on the control side so you can remotely switch it however you want to. (The same technique applies to larger DCs that don't already have a contactor based remote control system integral)

[Ralph Okonieski]

I use the Ivac contactor for my dust collector. It is excellent. A contactor is the best solution IMHO and not very expensive in the grand scheme of things.

[Richard Coers]

Do you have one, or which one did you recommend? The OP asked for a 30A and that one is rated at 30A.

[Greg Funk]

Do you have one, or which one did you recommend? The OP asked for a 30A and that one is rated at 30A.It's rated at 30A for a resistive load but a maximum 1HP motor. A normal motor will typically take 5-10x its rated current while starting, so contactors designed to handle motors are considerably more robust than the equivalent contactor for a resistive load. The Ivac switch mentioned above looks reasonable.

3HP contactors from Schneider, WEG, Franklin or other name brand electrical suppliers are also options but they are generally more expensive.

[Jacques Gagnon]

I use the iVac contactor (same as the one mentioned by Ralph) on my 5hp Clearvue dust collector. It works very well.

[Ian Lerew]

I have the PSI LR2244 but it doesn’t appear to be available anywhere. Like others have said your best bet would be to use a 120v remote controlled switch to turn on a electrically held contactor. You can get a 30 amp definite purpose contactor for around $30 on Amazon.

I made a remote setup so I could use any 110V lamp remote control to power my dust collector. Pretty east and it's been in regular use since I made it and installed it in 2004. So I'd say that the $65 I spent to build it and set it up, was money well spent. :)

I am looking into this option for my Oneida 5HP Smart Dust Collector. The factory supplied remote system on these units is not robust or reliable. I am on my 3rd remote transmitter/fob set in 6 months, all supplied by Oneida under warranty. My question is whether the ivac contactor solution can be installed DIY, or if I will need an electrician? All I am looking for is a robust, reliable way to start and stop my DC remotely. I open and close all blast gates manually, so not looking for ivac's automated blast gate system. Thank you for your help!

[ray grundhoefer]

I used a 120volt christmas tree remote and a 2pole contactor with 120 volt coil for my dust collector. Works great

[Robert Hayward]

I use this very remote to switch my 30 amp dust collector. Mine controls a $15 contactor though. The $15 contactor with a 30 amp rating has been working as intended for a couple years. The wire connectors on the remote are much too small to handle a 10 gauge wire required for 30 amps in my area.

[Bill Dufour]

Look on ebay to get a name brand used contactor with a 120 volt coil. Then control with the 120 volt remote of your choice. You just missed the christmas light remotes sale.

Brand new contactors are quite inexpensive...no need to order something used from the 'Bay, IMHO. The one I bought to control my compressor was a whopping $17 from Amazon with free shipping. 30 amp load with 120v control. Packard brand which is a small business.

Jim, I'm going to do this and couple it with my Lutron Caseta switch. Is this the model you found on Amazon - DP301202 C230B 2 Pole 30 Amp Contactor, 120 Voltage Coil? (don't want to post a link)

Same story here, and 2 yrs in operation. I use it to control the 120v coil 40A contactor for my dust collector. $14... doesn't get much cheaper or easier than that.

I had no idea they were that cheap new. I still prefer a used quality USA made one over a new made in China model. Of course adjustable overloads are a nice modern feature.

I built one using the parts shown from Amazon. Works just fine on my 2 HP grizzly dust collector. Been working just fine for the past 4 years. Jim

This is fascinating to me, that there might be such an inexpensive and simple fix to my problem. I'm not real well versed in electrical installations........is this something I can do myself, or should I hire an electrician? Is the contactor wired to the VFD? My system has a VFD to convert incoming single phase 240V to three phase on the motor (load) side. It also varies the motor speed, but I'm not clear what paces it (suction pressure or CFM).

thanks!

[Michael Burnside]

I think DIY is possible. The 2 poles break the two hot connections on the single phase 240 going to your VFD. Then for remote I plan to use a Lutron outdoor switch, cut the output side and gave it drive the contractor. There are cheaper switches but Lutron is instant, works on a dedicated FCC band and just works every time. I already have one for my CNC 120V DC and love it.

Loosely speaking (since I don't know what VFD or DC you are using)....
You don't need a Direct-On-Line (DOL) contactor if you have a VFD. The VFD can likely be programmed (set a parameter or 3) to allow an external switch to start/stop the VFD(& motor) via a discrete input to the VFD. The input will usually operate at 5VDC or 24VDC, and can be switched by nearly anything: a standard light switch, a remote, or a clap-on-clap-off.

I do this on my EF-5's Chinese VFD. The remote make/model I have escapes me at the moment (I'm on the road : can't see it)*, and Amazon has so many different options that my quick search did not find it.

As for pacing, VFD control via pressure or flow would require a sensor ($ transmitter $) for at least one of those processes, and so allow the VFD to modulate from that signal. If your VFD does in fact vary motor speed automatically, it is likely that it is programmed to keep the load at or near FLA (the VFD can 'see' the amp draw internally), and this is the basic SMART control on various DC platforms. I have made threats to do this FLA control my VFD, but in reality the DC works just fine as-is.

Be careful of installing a DOL contactor in series with a VFD. If upstream of the VFD, it is manageable. Sometimes. Make sure you can reach the fault reset button. If downstream (between the VFD and motor), it will almost always fault the VFD, and very likely permanently damage it.

As mentioned, it is just as easy to remote start/stop a VFD as it is a DOL contactor. No need for both.

I thought I was clear when I said "240 going TO your VFD". I never suggested intercepting the VFD output which would be patently idiotic IMHO.

Very clear. And clearly we are aligned. Good luck with your project.

I will spare you my experiences with patent VFD users.

Very easy if you think it through, but if you're not comfortable, get help from someone who is. These are basic devices. They are effectively an on/off switch but rather than having a handle you move with your fingers, they use an electric current to throw the contacts on/off. This allows the circuit you are wanting to control to be as beefy as you need for your application while you use either 120v AC or low voltage to provide control. The control doesn't "use" a bunch of power. It's just a signal. This is why you can actually use cheap holiday light remote switches on the control side to do the deed.

[Tim Greif]

Pretty simple DIY project. Here's a good example using stuff I found on ebay and Amazon. Square-D size 0 contactor for $30 on ebay already had a 115 volt coil. I used a Wifi outlet as a remote control switch to activate the 115 volt coil and close the contactor. You could just as easily use a normal light switch to control the coil using 115 volt shop circuit. My setup controls a 2-HP lawn irrigation pump at my river cottage pumping river water to the sprinklers. The Wifi switch lets me control it on a time schedule or direct from my phone from anywhere. I got the plastic weatherproof enclosure on Amazon. Works great. While I'm sure Jim's recommendation of Packard controllers is fine, I'm more comfortable with good old Square-D industrial stuff. Pretty bullet-proof regardless of age.

If you don't want to "roll your own", Clearvue has a package already put together. It requires a connection to both a 240V outlet and a 120V outlet, so I would imagine it uses a contactor similar to what Jim Becker describes above.

It supports a 5HP 240V motor at rated at 30 amps.

I finally gave up on the Oneida OEM remote control system for my DC. Am on my 3rd unit in less than 1 year and it's simply not reliable. I have ordered the iVAC Pro Magnetic Switch Controller and and remote system. The wiring instructions look pretty straightforward. Hoping this solves the problem.

Have any of you used the iVAC MSC, and if so, are you happy with it?

thanks!
