Controller that operates below zero celsius

klikopc · Feb 2, 2010

Can you guys name me a couple of controllers that operate to about -20 Celsius?
I need one to work in outside conditions for the entire year!

which one would you recommend?

An insulated panel with a panel heater can be a good choice to keep any controller running through the cold winter months.

That would work, but i need a guarantee that it will work at any time, even if power goes out for a day and the controller gets to below zero temperatures, like for example in a car. It has to start up without any problems once power comes back and is not yet heated enough!

For what it is worth, take a look at Schneider Twido Extreme.

I never used them but the specs may meet you needs. Operation spec from -40C to 110C. It looks like it is made for heavy machinery / construction vehicle use so I do not know if it will work on your app. No idea how much this costs either.

I think one of the other EEs here was looking to use a small micro GE Fanuc once that supposedly had the op. specs down to -20C. I don't know what model # but it might be worth a look at their site.

Hi klikopc

Ab has a version of the controllogix pac's called XT that can be used down to -25C.

its properly very expensive, but should do the trick

Siemens has a Siplus line that will work

-25 to +60 C

Ifm electronics has controllers for -40..85°C, not too expensive, programmable with CoDeSys.

Thanks for the info guys!

Those are just what i'm looking for!!!!

Even though I hate to bring this up, I believe most SCADAPack's by Control Microsystems are rated down to -40.

i only use WAGO as they can run below zero they have DNV (marine) approval.

And then there is always Sauer Danfoss Plus 1 that is designed for mobile applications. -40C is no problem.

But since the programming software is expensive I would go for IFM:

This is programmed in Codesys that is free!
