plc analog input module illustrate

In or on the value of time is called a continuous physical plc analog output modules. The analog plc intelligent controller indicating the called analog signal. Operating in the analog signal to an electronic circuit called an analog circuit. 
For example: 
Thermocouple voltage signal at the output of the work belongs to an analog signal, because in any case the measured temperature jumps are unlikely to occur, so the measured communication modules plc signal either in time or quantity are continuous. Moreover, the voltage signal of any value in a continuous process of change is a specific physical meaning, that means a corresponding temperature.
