Mitsubishi module FX2N-4DA overview:
Judging from the appearance of the fuselage, the appearance of Mitsubishi FX2N-4DA is almost the same as that of other models of analog input and output modules such as Mitsubishi FX2N-4AD and Mitsubishi FX2N-2DA. They have the same appearance and size. This is because the modular components are all assembled using embedded components, and the unified appearance greatly facilitates safety and use. Therefore, the main difference in appearance is to look at the description text on the fuselage.
Mitsubishi module FX2N-4DA :
Mitsubishi FX2N-4DA is an analog module. First, let me introduce to you the working principle of the analog module. The analog module converts pressure, liquid level, temperature and other signals into 1-5V, 4-20mA (there are also other signals, such as 0-10V, 0-5V, etc.) and then sends them to the PLC for processing. The PLC does not know the specific voltage or current signal size. Therefore, we need to use a number to represent its size, and then tell the PLC, so that the PLC can know the specific size of the input voltage and current signals.
Digital input and output signals are switching signals, 1 or 0. There are two types of analog signals, voltage or current signals, which are usually signals transmitted by a transmitter. For example, if a pressure transmitter is used to detect water pipe pressure, it will output an analog signal of 4-20ma or 0-10V to the PLC. , PLC for data processing.
For example, we now measure a temperature of 20 degrees (range 0-50 degrees, output range 1-5V). At this time, the voltage value generated by the temperature sensor is (5-1)*20/50=1.6V (The instrument characteristics must be linear to be calculated like this). After the PLC's analog input module receives the 1.6V input, it will convert it into a digital quantity. For example, the resolution of the analog input module we use is 0-4000 corresponding to 1-5V. Then, 2.0V should correspond to (4000-0)/(5-1)*1.6=1600. That is to say, after the PLC reads the number 1600 given to it by the analog input module, it can know that the temperature sensed from the temperature sensor is 20 degrees.
In the above example, the sensor range and output range are determined by the sensor. The resolution of the analog input module is determined by the analog module. The role of the analog output module is just opposite to that of the input module. It is used to convert digital information into 1-5V, 4-20mA. Multimedia entertainment functions

FX2N-4DA detailed description:
Mitsubishi FX2N-4DA has 4 output channels. Provides 12-bit digital input with high-precision resolution. The conversion speed is 2.1ms/4 channels, and changes in the number of channels used will not change the conversion speed. The output can be in the form of voltage or current. The choice depends on the wiring. During voltage output, the output signals of the two analog output channels are 0~10V DC and 0~5V DC; during current output, they are 4~20mA DC. The resolution is 2.5mV (0~10V DC) and 4uA (4~20mA). Digital to analog conversion characteristics can be adjusted. This module requires 8 I/O points. Applicable to FX1N, FX2N, FX2N sub-series. Other performances are similar to FX2N-2DA.
Data communication between the programmable controller basic unit and FX2N-4DA is also performed by FROM/TO instructions. The read and write operations are performed on the buffer register BFM of FX2N-4DA. The buffer area consists of 32 16-bit registers, numbered BFM﹟0~﹟31.
FX2N-4DA application scope
Applicable to: electric power industry, elevator industry, three-dimensional garage, automobile industry, automobile accessories, feed industry, aluminum smelting industrial machine, refrigeration industry, steel industry, combustion control system, non-ferrous metal smelting, glass industry, construction machinery, textile machinery, Water treatment and other industries
