They all won’t respond correctly to the sense input (TC, RTD, Voltage/Current) and 2 of them are stuck at -208 no matter what. I don’t see any glaring issues on the boards, the capacitors are all happy, nothing burned out/damaged. Can’t find any reference to them on the internet except for a manual here.

I’ve also got an Omega CN8500 with similar issues.

Anyone else familiar with these controllers?
