JBC T210 and T245
« on: January 09, 2020, 01:02:09 pm »
Hello. I'm new in this form. Sorry for my broken English.
I want to build a JBC station but all sources are supported by T245. I couldn't find any circuitry and software with T210 or NT105 support. Would you help me with this topic?12-0-24v 300watt toroid transformer I want to make a suitable system. because it works very well with the t245.

You should be able to use the exact same circuit for the T210 as for the T245. I didn't see any difference there.
A big difference is indeed if you try to use the Nano series (afair 7V heater instead of 24V, different controlling since the cartridges only have two pins) or the big 400 series (48V heater, but circuitry is identical).

But why should that be? it has the same pinout (except from the sense resistor at the middle pin) and the 210s work in any 245 station and vice versa. I have an original JBC and my DIY one, both irons work in both stations. please show the circuit diagram you built.

Sorry, I don't get it. Where on your board are the dual fets that blow? I just see a burnt contact on that connector.

Ok. So, what did you do to find the problem? It's like poking with a stick in a dark hole with that small information you give. Please try to list as many information as you can about what happened, when did it happened, what did you do then,..., so that we can find a way to solve your problem.

As I already wrote as an answer to your private message to me: no, I can't, since I don't have a schematic for it, nor the program anymore. it was just cobbled together stuff that was lying around.
Either way that wouldn't help your cause. You need to find out WHY stuff is blowing up, not just "ah, this doesn't work, lets use another project".
Besides that, my DIY solution is rather simmilar to the one you linked to, at least in respect to the power switch part, so that wouldn't help you either.

Registered for the sake of this message.
Also building a DIY station JBC. Also interested in connecting the C210 handle.
What did the author do? Burned a station and deleted messages?

As far as I understand in DIY stations or for example, Liesto for the C210 knob reduces the value of mV.

It is also interesting how the original JBC station understands that the C210 is connected to it. On C210, there seems to be one additional positive contact.

I didn't notice until now, that he deleted all of his messages. What is this nonsense?  |O

Yes, he blew his DIY solution but instead of trying to figure it out he wanted a ready to go circuit without any work for himself, at least that is what it seems like after this deletion orgy.

Also yes, the C210 seems to be sensed by the station by using that additional middle positive contact. I assume it measures some valie between GND and the middle contact, maybe a voltage or current. On one of the handpieces I have there is also a resistor connected to the middle pin, so that would support that.

What is your c210 handle? Chinese as I understand it? Can you give a link?


It would be interesting to understand what is changing in firmware when the station realized that a C210 handle is connected to it.

Or is it just that the resistor limits the current and this is where all the magic ends?  :-DD

it's this one. Don't know where JBC produces their handles. https://www.weidinger.eu/shop/loettechnik/jbc/jbc_loet-_und_entloetgeraete/jbc_loet-_entloetkolben/wl13282

I assume it changes pretty much nothing, except maybe some PID parameters. in my DIY station I don't care which tool is conected. if it heats, it heats. the thermo junction is identical, so the software can handle both.

I doubt that you would like to hold a resistor in your hand, that reduces the current from a PSU capable of delivering 50 Watts to something a 20 watts iron can handle ;)
