Modern power relays for 120VAC?

Got room for a socket? Use a contactor.

Or buy one of the infinite gain units from Larkin :-) ...Jim Thompson

P.S.: Low contact resistance is also important. The usual 20mOhms is a bit much.

We use this:

TYCO PB T90N1D12-24

That, John, is a far better reply than JT's, which was insulting you and inviting your response. You will do good by not replying to his post at all, since it means nothing.

Just my opinion.

Thanks, I've already looked at that one, and pretty much all others that Digikey, Mouser and Newark carry. It spec's contact resistance at 75mOhm max. In reality I am quite certain it'll be under 25mOhm but at 20 amps that's still a whopping 10W. I think I am going to look at solar inverter stuff. Their relays are much better in contact resistance and they often have a "green spec", meaning they have the coil hold current right in the datasheet.

That's how much he knows about relays... nothing.

Besides, I have to keep friendly with Joerg. He owes me a beer.

Ga-a-a-awd! Another PLONKER.

John would be insulted, no matter what, for he's also a PLONKER.

Look up the definition... it was O'Reilly's word of the day, yesterday. ...Jim Thompson

And I still have the wooden beer coin for Zeitgeist somewhere around here :-)

Jim's classification doesn't need looking up: redneck asshole.

Gotcha, Ol' "Infinite Gain" :-)

But you're such a plonker, you don't really know what a redneck is.

I don't know why you need to be such a turd, but why don't you move yourself (the turd) outside with your "parentage", the dogs? ...Jim Thompson

Not to turn this into a beer thread..... but I had a Samuel Adams Apricot Ale the other day (imported from across the pond, supposedly). Damn fine stuff! Quite taste-y. And I'm usually very picky about brews.

Total Wine carries it locally. If you ever get the chance, try it.

Hello,

I looked for a power relay here

Relays are a very, very mature product line. I'm not sure what you were expecting to happen in the past few years!

You can't budge any of those specs?

If the steady state coil power dissipation is a big deal, high amp relays with "pull-in coils" and "hold-in coils" (we called them "contactors" or "solenoids" back then) were popular in the past but I don't see them in the catalogs anymore.

I'm not sure who is selling your end product but if it's going to have a name like HONEYWELL on it you know they want you to make it so it costs them $5 but they sell for $800, right?

I really don't like beer with fruit or spices in there. Almost every time we end up with a sampler pack there is a cinnamon ale or whatever in there. Blech! The exception is a spritz of lemon in lighter lagers, and only during hot summer months.

Yes, those are contactors and they are the best. But unfortunately I don't have the room for such a monster size relay. It has to go on a little circuit board :-(

I've looked at solar inverter relays and bigger 30A pump relays. None has two coils but I can pull in and then PWM them. Cajoling the inductive data and the plunger mass out of the manufacturer promises to be fun, that'll be on the calendar today :-)

No, this is a very different business :-)

We love Purple Haze, a wheat beer from Abita Springs, that has just a hint of raspberry.

Cinnamon ale sounds dreadful.

That depends on the definition of "hint". If I can taste it I'd probably not want another one.

The worst are pumpkin ales. But then again I also do not like pumpkin pie.

Well, you like those bitter hoppy things with optical densities around

I have a pumpkin phobia, but the story is too terrible to repeat.
