Could some expert please explain what high-level analog input and low-level analog input are? I’m not sure about these two concepts right now. Thank you! !

A high-level analog input refers to a module for receiving 4-20mA analog signal inputs, while a low-level analog input refers to a module for receiving signals from thermal resistors and thermocouples. Is it Honeywell’s system?
