[smartBridges] ABO differnece between ABI???

[Blazen Wireless]

Okay what is the actual difference between these two units? I have heard = mixed responses that they are the same unit just a different case. Are = the ABI able to handle the same heat and cold as say the ABO if mounted = inside a nema type enclosure? Has anyone been using these in an outside hot and cold environment?
