FX1S Series:
Mitsubishi PLC is an integrated small unit type PLC. And it has intact functions and communication functions and other scalability. If you consider the space and cost of the installation, it is an ideal choice.
FX1N Series:
It is a popular PLC with strong functions from Mitsubishi Electric. It has the scalability of extended input and output, analog control and communication, link function, etc. It is a Mitsubishi PLC that is widely used for general sequential operation.
FX2N Series:
At the time, it was the Mitsubishi PLC that was the most advanced series in the FX family. It features high-speed processing and the ability to expand many special utility modules to meet individual needs, providing maximum flexibility and control for factory automation applications.
FX3U Series:
It is a new third-generation Mitsubishi PLC recently launched by Mitsubishi Electric Corporation, which may be called a small supreme product. The fundamental function of the transistor output type has been greatly improved, and the basic unit of the transistor output type has a built-in positioning function of 3 axes with a maximum of 100kHz, and a new positioning command has been added, which makes the positioning control function stronger and more convenient to use. The FX3U series is a replacement for the FX2N, which was discontinued by Mitsubishi Electric in December 2012. In the future, everyone will choose the FX3U series. Mitsubishi PLC-FX3U series product introduction:

● The module can monitor and test the soft components and set the clock.
● The FX3U series can also install the display module on the panel of the control cabinet.
● FX3U series PLC programming software: GX Developer 8.23Z or above is required.
FX3G Series:
It is a new third-generation Mitsubishi PLC recently launched by Mitsubishi Electric Corporation, the fundamental unit comes with two high-speed communication interfaces (RS422&USB, built-in up to 32K large-capacity memory, the fundamental instruction processing speed can reach 0.21μs in the standardized form, the control plan: 14-256 points (including CC-LINK network I/O), the positioning function is simple (up to three axes), and up to 4 FX3U special adapters can be connected to the left side of the fundamental unit, which can realize floating-point arithmetic. You can set a two-level password, each level of 16 characters, to enhance the password protection function
FX1NC FX2NC FX3UC Mitsubishi PLC:
While maintaining the original robust function, a very considerable plan was realized, and the I/O type wiring interface was reduced, which reduced wiring costs and greatly saved time.
Q Series Mitsubishi PLC:
Mitsubishi Machinery Co., Ltd. launched a large PLC, CPU types include basic CPU, high-performance CPU, process control CPU, motion control CPU, redundant CPU, etc. Able to meet all kinds of complex control needs. With the rapid development of Mitsubishi Electric's business in China, in order to better meet the requirements of domestic users for the high function and low cost of Mitsubishi PLC and Q series products, Mitsubishi Electric Automation has launched an economical QUTESET type Mitsubishi PLC, that is, a 5-slot Q00JCOUSET with a 64-point high-density hybrid unit; The other 8-slot Q00JCPU-S8SET, which comes with two 16-point switching inputs and two 16-point switching outputs, is fully compatible with Q00J and fully supports software such as GX-Developer, so it has an excellent cost performance.
A series Mitsubishi PLC: using Mitsubishi's special sequential control chip (MSP), the speed/instruction is comparable to that of large Mitsubishi PLC in the United States; A2ASCPU supports 32 PID circuits. The number of circuits in QnASCPU is unlimited, and can be changed with the size of the memory capacity. The program capacity ranges from 8K steps to 124K steps, and the memory of QnASCPU can be expanded to 2M bytes if a memory card is used. There are a variety of special modules to choose from, including network, positioning control, high-speed counting, temperature control and other modules.

Advantages of Mitsubishi servo system:
The servo system is an automatic control system that makes the output of the object's position, direction, and condition change according to the arbitrary change of the input quantity (or given value). In the automatic control system, the system that can echo the control signal with a certain degree of accuracy is called the follow-up system, also known as the servo system.
