Plc analog output mod

In or on the time value of the physical quantity called continuous analog, plc digital input output module, respectively, generally with AI / AO, said. PLC analog output mode refers to the amount of the size of the control system is a continuous value in a certain range, such as temperatures, from 0-100, pressure from 0-10MPA, the opening degree of the liquid level from 1-5 meters, electric valve from 0-100%, and so on, these quantities are analog.
Outputs for analog is "analog output plc." The most common places electronic technology, such as DA conversion output is the analog current / voltage (continuously variable current / voltage), plc analog output module of the rectifier circuit is analog. Mathematically, if the physical quantity of an output at time t a (t) form a (t) = F (t) is a continuous function, then the output of the analog.
