MELSEC L Series

The MELSEC-L Series will innovate and evolve your production site.

Its site perspective achieves excellent ease-of-use.

The MELSEC-L Series has been designed based on a passion for monozukuri (creation), trustworthy technology and reliability. This concept also applies to system installation and operation.

With various I/O functions as standard inclusions, the MELSEC-L Series serves to improve work efficiency by realizing convenience, ease-of-use, and diverse control.


Overview




Convenience that fits in the palm of your hand

The L Series is a compact-class controller, part of the MELSEC products renowned for exceptional cost verses performance and strong reliability.

It provides the performance, functions, and capabilities required for today's demanding applications in a small package.

MELSEC-L Series greatly expands the range of functionality traditionally associated with compact programmable controllers and through user-centric design, pushes the limits of ease of use.


Ideally configured to satisfy the applications requirements

MELSEC L Series has been designed with three key concepts in mind.

Reliability

Robust and trusted MELSEC product quality.

Ease-of-use

Enabling engineers and programmers to do their job as efficiently as possible to reduce costs.

Flexibility

L Series is a cost-efficient control system flexible to various applications, enabling an ideal system design.


 

The CPU module contains a diverse range of control functions

A large variety of I/O types and features are built-in for convenience.

Due to an abundance of advanced functionality, L Series CPUs are flexible enough to meet a wide variety of needs.


 

High speed, large memory capacity CPU

The CPU has a basic operation processing speed of 9.5 ns*1 and 260K steps*2 of program capacity ideal for complex programs and equipment control.


*1: For L06CPU(-P), L26CPU(-P), L26CPU-(P)BT

*2: For L26CPU(-P), L26CPU-(P)BT




Advanced capabilities focused on improving efficiency

The user-friendly display unit enables routine operations to be made without a computer. An SD memory card slot*3 is included as standard for data logging and program storage. Write programs and manage L Series controllers using GX Works2 and iQ Works, the most advanced and effective software for Mitsubishi controllers yet.


*3: Included with L02CPU(-P), L06CPU(-P), L26CPU(-P), L26CPU-(P)BT
