plc analog input module is continuously changing physical

plc analog input modules are continuously changing physical quantities such as voltage, temperature, pressure and speed, such as PLC, can not directly handle digital output plc‍, analog input module requires use of A / D converter converts the analog input signal into a proportional to the digital. PLC in digital (such as the output of the PID controller) with analog output module requires the programmable logic controller plc‍ converter to convert them into the corresponding digital proportional voltage or current for external actuators (eg electric control valve or drive) to use.

plc analog input module volume manometry explanation

plc analog output modules measured voltage values​​, active power, reactive power, temperature, etc. and transformer tap positions measured value represents the amount of profibus module plc‍ quantities (also known as logical volume) control, also known as analog. Hitachi reagents because the instrument is not to draw the lessons by volume parameter settings, but to be more absorbing part (in this section referred to as analog), the purpose of this design is to prevent high-speed counter plc‍ diluted. Compare it to the operating mode changes continuously called physical analog. Multimeter pointer deflection intercropping continuous change at any time, and maintain a correspondence between the input, so called analog multimeter (VOM).

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.‍

plc analog io module for two-point conversion

Analog plc analog io modules for converting the two points (voltage value and current value) of the analog input value of the digital value 12, and the process is further plc power supply module‍ to a control value (here, the PLC). FX2N-2AD can be used to connect FX0N, FX2N, FX2NC series of procedures and control systems. 

(1) analog value is set by selecting the input voltage or current value (using the cable way to enter) to complete. Meanwhile, the general assumption set two-channel analog input values ​​(voltage or current values​​). 

(2) The analog input industrial automation plc‍ ​​of these two channels can accept 0 ~ 10V DC (points), 0 ~ 5V DC, or between 4 ~ 20mA, please select your eigenvalues ​​in these two ranges. 

(3) The analog input value is adjustable. 

(4) The module can automatically allocate 8 I / Point O (input / output) to the input or output value.‍
