Kiln PID Controller retrofit?

I've ran a cheap SSR on my CNC router to control the spindle for a couple of years now. I've not had any issues with it and so far not worried with it. I will admit that I over rated it by 200%

 

Kelly, You're over 50, forget it. If you are anything like my parents, setting the clock on a VCR is mission impossible. Mail it my way.

 

The versions I have are labelled REX C100, I left a comment on a youtube video with two different parameters that had to be changed, one unlocked a configuration menu and the second set the upper limit to 1500 deg C, I'll see if I can find the exact video, it's been a while.

I'll take a look at those XMTG-8000 controllers, as for the REX C100, there's this other video:

 

Good! Maybe Kelly can do a ramp and soak video for those of us approaching 50 that are VCR clock retarded.

 

How about this one? I suffered through the video, but near the end, he talks about a ramp up and soak. Funny how no where this thing is sold mentions how many friggen segments it has. It's cheap as chips. https://www.aliexpress.com/item/Fre...troller-for-Industrial-Usage/32773825607.html Anything with segments listed on fleabay is 80bucks.

I'll save you some time... start around 5:20 and follow him to the end.

 

Here it is on Ali... These jokers cant even agree on the damn model number.. XMTG or XMTD... WTF?

Instructions here. Looks like it's just the size.

It looks like a real ramp-soak controller according to the video, why would you buy the basic REX C100 knock off when you can get one of these for a few bucks more.

 

I took the bait. That controller is 220vt 50/60 is the only I saw... So I grabbed it, a 60amp relay and a ceramic t-couple. With a 4buck coupon, I was out the door for $25bucks. What a deal.

 

He even posted how to program this thing to do ramp soak as the manfct. instructions suck. Pg 4 has the nitty gritty for this controller. Bless his little vodka filled heart!

The answer btw is 32. This thing has 32 segments! kickazz!

 

A lot of those have switchmode power supplies good for 100-250VAC it would be unusual to be 250V only, though weirder things have happened.

 

Good point mark. These asshats cant even decide what the correct model number is. I can try shoving 110 at it and see if she chooches.
Now that I'm about to be armed with a competent controller, it's time to figure out the annealing schedule.

 

You might look at the power input connections on the back, they may list the voltage. Or not.

 

Looks like the fourth letter denotes the physical dimensions of the unit and from some of the Ali Express ads it's powered from 220VAC +-10%.

 

That looks like the resistive temperature device (RTD) version of the XMT-7000 unit (thermocouple). This Alibaba ad for it claims it's 220VAC +-10% and then in the same line says it runs off 85-265VAC: https://xmxbl.en.alibaba.com/produc..._XMT_8000_digital_temperature_controller.html it seems there's always an element of surprise in the specs, like other controllers with electromechanical relay output that claim to be SSR outputs.

 

Yeah, those stupid clowns always have screwed up descriptions. I hope it's 85-265... but won't be butthurt if it's not. Alibaba is decent if you don't mind buying in bulk. For onesey twoseys it's aliexpress for me.

Thanks for posting that Kelly. I have printed it off.

 

I read that as a 220 volt AC input, ie: it is designed to plug into the wall in Europe, not in the US.

Will it run off of 120 VAC?
I would assume no, else it would not say 220 VAC, but that is just my guess.

I thought I posted this stuff somewhere here, but I am not seeing it.
This is what I bought.
I don't have it operating yet, but think it will work (I hope).
Everything was purchased on ebay.
I bought some big aluminum heat sinks too; I don't recall if I needed one or two.

And it does say 90-260 V, AC/DC, and I run my controller with a 120VAC power, so I guess my assumption above was wrong?

The instructions are in Chinglish, so a little tricky to understand, but not too bad.

If you forget to buy a heat sink, you will burn up the SSR.

 

I went with a 100 amp unit on the Fotec SSR.
This cut sheet goes up to 75 amps, but I think the one I bought is 100 amps.

The nameplate on my larger kiln says 10,350 watts at 240 volt, 1-phase, 45 amps, and it uses a 2-pole breaker which I think is a 60 amp unit.

You want devices rated at least 125% of your full load current.
