    REX-C100 PID (cheapest PID on ebay)

    It's not necessarily the PID, could be your T-couple.

    REX-C100 PID (cheapest PID on ebay)

    Uhm.....cheap chinese PID some of which (non-counterfeit too) behave as dexcribed here (DOA) http://www.smokingmeatforums.com/t/148997/mypin-ta4-pid-manual-programming-instructions-and-general-pid-ssr-info-by-request VS Not so cheap Japanese for the same price? I have not seen the TA4 manual...

    REX-C100 PID (cheapest PID on ebay)

    Been a while since that thread had opened... Wanted to share: on eBay there sometimes are the real ones, not counterfeits being sold. About a month ago while dealing with a real one at work bought directly from RKC Instruments (for cooling prj) I decided to see if they are sold (used obviously)...

    REX-C100 PID (cheapest PID on ebay)

    Make sure your unit says explicitly 110V/220V"" and not "220V" only. They sent me one like that with SSR control, and it powers, but does not really measure correctly. It says 220V but they claimed it works from 110V. They did send me replacement for 110V but that was relay unit; I desoldered...

    REX-C100 PID (cheapest PID on ebay)

    Where's the e-bay link? A PID is a temperature controller, that has a complex algorithm of controlling a heater (a cooler) using "Proportional, Integral or Derivative" functions - read Wikipedia, if you are interested, it is quite simple.

    REX-C100 PID (cheapest PID on ebay)

    Well, mine is also in C, and had it been the real thing (not a counterfeit) - it has a variable that changes C to F. But I went through the variables - sure enough, it's not there. You get what you pay for, but most of the time it is enough. :)

    REX-C100 PID (cheapest PID on ebay)

    From my own experience - it is not the same. The ones you buy on e-bay from Hongcong are most of the time counterfeits. They, yes, are PIDs and they work, but they are not in agreement with the REX C100 manual, the names of the variables are different, and one of the two I bought is just...

    REX-C100 PID (cheapest PID on ebay)

    Hey guys, thanks for the feedback: I was actually able to open the unit that same day posted here, with a bit more persistence on my part. De-soldered the relay, completed the mod. Ferari12, Yes I did run "ATU" (its autotune) and the operation I described to you was in fact after it was run...

    REX-C100 PID (cheapest PID on ebay)

    Thanks, mattd2, I think I'd be able to figure it out once I open the box. Myself I am an EE, so circuitry is no mystery - what's mystery is how to open the dang thing - doesn't seem to want to let me do it to it. The tab I have at the front panel doe not release anything once pressed. And Since...

    REX-C100 PID (cheapest PID on ebay)

    Actually I just realize the one I got for the SSR is defective - this is why it measures -55C when it is 25C. The other one, with the relay output, measures all correctly - boiling water is 100C. So how did you say you popped up the case? :) Can't see any tabs. I don't think this Chinese guy...

    REX-C100 PID (cheapest PID on ebay)

    Hey guys, I am new here and just saw that thread - was looking for C100 setup. But I wanted to tell you this: on ebay those guys sell "M"-type C100 (relay output). However the guy clearly advertised SSR drive output ("V"-type). Here's what I did - I wrote the guy and he admitted the error...
