I will update more later - The board has not failed - Its still working.
TTL outs - they drive simple ssds.
The reason I said "failing" because temp sensors start disappearing after few hours. After cooling the CAI- they come back!! (they are from Amazon, US supplier - So hopefully has some QC compared to Chinese suppliers)
The reason we need "industrial" boards is because they just need to work without thinking of cooling etc. The same box housed SSRs and PLCs - They work. Now I have moved it out in the sun(and they still work!)
The board is being used at roof(there are no furnaces here). The HVAC (Carrier) is on roof and in sun- And it houses a lot of electronics(their CCN network, which are 2 full sized ISA sized boards), even LED display.
I understand there are a bit of compromises - 40 odd USD cannot be compared to 200+ Siemens PLC, but still - This is no outside use board. It needs protection - in the same league that of pi boards etc.
PS - Direct sunshine is usually 5-7C higher as we measure on tiles on the roof. The Electrical box is open from below - so temp inside the box should be approximately the same as air temp outside- and today was 45 max.
