Programmable Controllers
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.
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
CPU
Module for PLC system control.
The L Series CPU features a variety of I/O functions as standard inclusions.
Customize it to include the functions that suit your application, and enable various control applications.
Branch/extension module
This module allows the system to be extended to match the size of your production facility.
Power supply
Module for electricity supply of CPU, input/output, and other modules.
I/O module
These modules use an analog method for data input/output. They achieve fine-tuned control with high-speed, high-accuracy, and high-resolution.
Analog I/O module
These modules use an analog method for data input/output. They achieve fine-tuned control with high-speed, high-accuracy, and high-resolution.
Counter module
Easily and accurately count high-speed pulse with this module.
Positioning module
Modules for high-speed, high-accuracy positioning control.
Information module
This module allows the exchange of information with the control system host.
Control network module
Interface module group for control-system networks.
Each FA level is seamlessly integrated with a diverse network.
Option
We also provide an extensive lineup of peripheral products such as connectors for input/output modules and industrial hubs.
