I don't change any cable or connection and 24V input is stable. No led turn on and I don't know what happened. a way to understand what happened exists? maybe chacking with a tester if all parts receive sufficient voltage? or maybe exist a fuse o a security hardware to check? thank you very much

And I also don't know how to check what is broken. What I can tell you is that I had the same issue with two IOT2050. But this was caused by myself by creating a short-circuit with an Arduino shield. Are you using a shield? Regarding this hardware issue you can try to contact your local Siemens Support and ask for Repair or Replace. Best regards!
