You probably want to start with a 3 phase contactor and drive THAT from one of these remotes... https://uk.rs-online.com/web/p/contactors/3949790/ ....could be driven by a simple mains switching remote. I'd put a damn great red button break in series with it tho for when the remote doesn't work... Harry has a very good point! -- Truth welcomes investigation because truth knows investigation will lead to converts. It is deception that uses all the other techniques. |

I have 13 amp sockets which I can control using a mobile phone. The sockets use wifi to connect to my broadband router. -- Michael Chare |

Whoops This is what I was referring to https://www.amazon.de/AC80-260V-1Cha...2B0W7XVA63TRJ8 As the others said, it won't control a three phase load directly since its intended as a light switch it will be only switching one pole, and you need three or four (depending on if your three phase machine has a neutral or not), and also it will have very limited current switching capability (and that might be even more limited when switching inductive loads like motors). You could use it to remotely switch a three phase contactor or possibly even a variable frequency drive. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Yes you would need a relay, but surely if you are going to actually use this machine, would not somebody be operating its other functions, you need an NC machine to be able to do all the adjustments remotely. I cannot think of any reason for doing this unless you are machining something radioactive or toxic like beryllium or plutonium! It could be a big 3 phase pump or something like that. Lots of them around here, its an irrigation area. Some feeding massive great lateral move sprinkler systems. "John Rumm" wrote in message o.uk...

UNBELIEVABLE: It's 07:28 am in Australia and this Senile Australian Cretin has been out of Bed and TROLLING for OVER SIX HOURS already!!!! LOL
On Wed, 11 Mar 2020 07:28:29 +1100, cantankerous trolling geezer Rodent
Speed, the auto-contradicting senile sociopath, blabbered, again: FLUSH senile asshole's troll**** 07:28??? LOL Don't you want to sleep and die AT ALL, you obnoxious pest? LOL -- Marland answering senile Rodent's statement, "I don't leak": "That¢s because so much **** and ****e emanates from your gob that there is nothing left to exit normally, your arsehole has clammed shut through disuse and the end of prick is only clear because you are such a ******."

Not having seen the documentation for it, its hard to know if it also supports remote switching. If it does then that might be ideal. and this the remote https://www.amazon.de/AC80-260V-1Cha...2B0W7XVA63TRJ8 Its to be used as remote control for this https://uk.feldershop.com/en/Extract...-3x-400-V.html IIUC that model is available with the choice of single or three phase motor. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Not having seen the documentation for it, its hard to know if it also supports remote switching. If it does then that might be ideal. It should do. The green button is a push to make spring loaded switch. There are usually terminals available for remote switching (I know it says remote switching on the diagram but that would apply to the green button on the DOL. Note the hold on contactor in the diagram. https://www.electronicshub.org/dol-starter/ and how the red stop switch (locks when you press it and needs a manual turn to reset it) will kill the power even if the green button is pressed. -- Adam |
