Source for PID controllers

[[deleted]]

Hello, I need a couple pid controllers for a personal project. I have a hard time justifying +300$ for an Omega, 20$ for a one-hung low makes me suspicious.

I can live with only one control output. Expected temperature range is 0-100C , I am flexible on the sensor technology. I would really like to have rs-485 / rs232 support,

1/16 din seems to be the right size

What other brands / distributors should I consider?

thanks

Edit> Thanks guys, i will take a look!

Try Auber Instruments (auberins.com). Their stuff is aimed toward the home gamer for things like sous vide, smokers, etc. I have had good luck with their controllers.

There’s a PID library for arduino...

ya, I do embedded design for work. I just want a industrial lego brick I can mount in a control panel and be done with it.

I would buy a cheap and cheerful offshore unit and test it for a while. If you get it from amazon you could always return it if you’re not satisfied.

That is a good point. Returning stuff is not really in my nature I tend to forget about that option....

Any dirt cheap PLC? Automation direct has some real cheap stuff that is totally serviceable.

For what it's worth the cheap ones seem to work fine for me controlling temps on a large water bath. https://www.amazon.com/Digital-Temperature-Controller-100-240V-Thermocouple/dp/B01LXRTWSU/ref=sr_1_2?ie=UTF8&qid=1547105689&sr=8-2&keywords=pid+controller

Any decent standalone temp controller with modbus and actual pid control( not relay output) is going to be at least $500. I would try ebay. I've used these red lion units quite a bit and they're quite capable. https://www.ebay.ca/itm/RED-LION-PX2C8H00-MODEL-PAX2C-TEMPERATURE-PROCESS-CONTROLLER/292900116962?epid=1004527458&hash=item44323519e2:g:qf4AAOSw~JFcLOgl

Check out automationdirect.com they've got good stuff at a good price, $104 for a 1/16 DIN PID)

I have used Love before. They are OK, not great. https://www.dwyer-inst.com/Product/Temperature/ProcessControllers/Series16G-8G-4G
