Product Description

AB AB 1756-L71 Controller, 2MB, 0.98MB I/O Memory, USB Port, Chassis Mount

 

 

1756-L71 Description
The Allen-Bradley 1756-L71 is a high-performance ControlLogix 5571 series programmable automation controller (PAC) from Rockwell Automation. Designed for complex, demanding, and high-speed control applications, it serves as the central processing unit for large-scale industrial automation systems. It combines powerful deterministic control with advanced information processing capabilities, making it ideal for applications requiring integrated motion control, process control, high-speed discrete control, and extensive data handling. The L71 is a core component of the Integrated Architecture system, enabling seamless integration across control, communication, and information layers.

 

1756-L71 Features

  • Powerful Multi-Discipline Control:​ Executes ladder logic, structured text, function block diagram, and sequential function chart programming to handle discrete, process, safety, and motion control within a single controller.
  • Large Memory Capacity:​ Features a substantial embedded user memory for storing extensive application logic, tags, and data tables to support complex programs.
  • Integrated Motion Control:​ Supports time-stamped motion instructions and direct integration with Kinetix servo drives via CIP Motion over EtherNet/IP, enabling precise coordinated motion applications.
  • High-Speed I/O and Communication:​ Multiple communication ports support high-speed deterministic data exchange with I/O modules, drives, and other controllers over EtherNet/IP and ControlNet networks.
  • Enhanced Security:​ Provides features like user authentication, program source protection, and change detection to help secure intellectual property and control system integrity.
  • Modular & Scalable Design:​ Part of the ControlLogix chassis-based platform, allowing for easy system expansion with additional I/O, communication, and specialty modules.
  • Integrated USB Port:​ Enables direct connection for program upload/download, controller configuration, and firmware updates.
1756-L71 Material & Applications
  • Materials:​ The controller features a robust metal chassis with an aluminum heatsink for thermal management. Internal components include a high-performance microprocessor, RAM and Flash memory chips, and industrial-grade electronic circuitry. The faceplate is made of durable polycarbonate with status LEDs.
  • Applications:
    • Complex machine control and large-scale production lines.
    • Integrated motion control systems for packaging, assembly, and material handling.
    • Batch and continuous process control in chemical, food & beverage, and pharmaceutical industries.
    • Major infrastructure systems such as water/wastewater treatment and energy management.
    • High-speed discrete manufacturing requiring precise synchronization and data collection.
