Mitsubishi Electric PLC CPU Module Product Description

Mitsubishi Electric's PLC CPU modules are the core of its automation control systems. The product lineup covers a wide range of needs, from compact devices to large-scale process control, and is mainly divided into five series: MELSEC iQ-R, MELSEC iQ-F, MELSEC-L, MELSEC-Q, and MELSEC-F.

Core Series Overview



Series Positioning Key Features Typical Applications
MELSEC iQ-R Next-generation PAC (Programmable Automation Controller), medium- to large-scale control High-speed system bus, program capacity from 10K to 1200K steps, supports dedicated CPUs for process, safety, motion, etc. Large-scale systems requiring high speed and high precision, such as automotive, semiconductor, and process industries
MELSEC iQ-F Next-generation compact controller, small- to medium-scale control Built-in Ethernet, analog, positioning, and other functions; instruction speed as fast as 34 ns Small equipment, stand-alone machines, IoT edge control
MELSEC-L Base-less modular controller, space-saving Integrated CPU with built-in I/O; instruction speed as fast as 9.5 ns; maximum program capacity 260K steps Equipment with limited space, small and medium-sized production lines
MELSEC-Q Multi-CPU architecture controller, medium- to large-scale control Supports multi-CPU cooperation for process, C language, motion, robotics, etc. Systems requiring complex calculations or multi-axis motion
MELSEC-F Classic compact controller Integrated power supply, CPU, and I/O; highly cost-effective Simple logic control, small machinery

Main Features and Functions

Mitsubishi PLC CPU modules share the following common technical characteristics:

  • High-Speed Processing Capability: The basic instruction processing speed of the iQ-R series can reach 0.98 ns (e.g., R04CPU), the L series can reach 9.5 ns, and the iQ-F series is 34 ns, meeting the real-time requirements of high-speed production lines and precision control.

  • Flexible Memory Capacity: Program capacity ranges from 10K steps for entry-level iQ-R models to 1200K steps for process CPUs. Users can choose flexibly according to system scale.

  • Rich Built-in Functions: Modern CPU modules generally include a built-in Ethernet port, USB interface, and SD memory card slot. Some models also integrate analog I/O, high-speed counters, and positioning functions, reducing the need for additional modules.

  • Dedicated CPU Expansion: For specific needs, Mitsubishi offers dedicated modules such as process CPUs (for advanced PID loop control), safety CPUs (compliant with ISO 13849-1 PL e / IEC 61508 SIL 3), and motion CPUs (controlling up to 32 axes).

Application Areas

Mitsubishi PLC CPU modules are widely used in various industrial automation scenarios:

  • Manufacturing: Production line control in automotive, semiconductor, electronics, packaging, food and beverage, and other industries.

  • Process Industries: Process monitoring and PID control in chemical, pharmaceutical, cosmetics, and other industries. The iQ-R process CPU can simultaneously perform advanced PID and high-speed sequence control.

  • Infrastructure: Redundant control systems for social infrastructure such as water treatment, power, and transportation.

  • Machine Control: Equipment requiring high-speed positioning and motion control, such as machine tools, injection molding machines, and textile machinery.

Overall, Mitsubishi Electric offers a comprehensive selection of PLC CPU modules through the MELSEC series. The iQ-R is aimed at high-performance and large-scale systems, the iQ-F and L series focus on compactness and integration, the Q series provides multi-CPU cooperation capability, and the F series focuses on economy and practicality. When selecting a model, comprehensive consideration should be given to the project's specific requirements for processing speed, program capacity, built-in functions, and special control (process, safety, motion).
