ET-AI-08 module is euipped with 8 analog inputs 0/4..20mA and -10/0..10V (each channel has contacts for current and voltage input).
Module ET AI sends information by ET-BUS, together with accurate time stamp of the event, to CPU module ET-CP.
ET-AI module has internal diagnostic system, which transfers actual working parameters and error information to the CPU ET-CP. Programmer can use this data e.g for alarming needs or presentation of controller's status to a user.
