Programmable Logic Controllers PLCs


With the AC500 PLC range we provide a reliable and powerful platform to design and create scalable, cost-effective and flexible automation solutions.



  • The scalability of the AC500 PLCs is achieved by offering a large variety of devices to design and implement configurations suitable for simple control tasks or complex automation solutions.
  • The AC500 PLC provides action flexibility with one integrated software.


  • The AC500 PLC range consists of various CPUs, I/O modules, communication modules, communication interface modules and accessories.
  • The “all modules used on any CPUs concept” in combination with our life cycle policy helps our customers to react quickly, flexibly and economically on new requirements.


  • Our AC500 is designed to offer the needed easiness, security and reliability to expand the automation system to new challenges.
  • The memory, performance and the networking capabilities mean more functionality, advanced visualization, more operating comfort – for even better individual customer solutions.

The AC500-eCo from ABB is a range of scalable PLCs offering cost effectiveness for modern industrial automation applications where small flexible PLC solutions often represent the ideal solution.



    • Save money by starting small - the flexibility of the AC500 platform enables to scale up as and when needs dictate.
    • ABB’s AC500-eCo has been designed to integrate seamlessly into the broader AC500 family, offering you the decisive benefit of having a fully scalable and modular system.
    • The AC500-eCo offers individually customized solutions to be created by using S500 and S500-eCo I/O modules for small applications.
    • The Automation Builder engineering suite available across the entire AC500 PLC range will save you time with easy configuration, many libraries and function blocks for the most diverse specific customer requirements.

Easy handling

    • The user program can be downloaded via a SD card without the need for programming tools.
    • CPUs with integrated I/Os for small applications available.
    • Pre-wiring is possible via the use of pluggable terminal blocks.
    • The modules can be fitted to the DIN rail with easy-to-use snap-on mechanism.


    • The AC500-eCo is approved for customer use by accredited certification organizations around the world. This means the entire range can be deployed safely, reliably and globally.

When it comes to reliability, efficiency and flexibility in safety automation, for over 30 years, ABB has been the partner experts rely on to cover even their most complex applications. Our engineers are known around the globe for their innovative and solid approach aimed at protecting people, machines, processes and the environment.

  • Certified for SIL3 (IEC 61508, IEC 62061, IEC 61511) and PL e (ISO 13849-1) safety applications.
  • Both PROFIsafe F-Host and F-Device functions over PROFINET are supported including the connectivity to more than one F-Host.
  • Ideal choice for both simple and complex functional safety applications like material handling (cranes, hoists, mobile platforms, distribution centers, harbors, airports, etc.), robotics, wind turbines and many more.
  • Separate safety CPU offers the benefit of safety functions which remain active even when the non-safety control is inactive.
  • Able to handle floating point data type resulting in highly accurate calculations for controlling speed, position, etc.
  • Comes with a full range of trigonometric functions often used in precise measurements involved in crane applications.
  • Offers greater flexibility and simplicity due to programming in Structured Text (ST) as well as Function Block Diagram (FBD) and Ladder Diagram (LD).
  • The configuration and programming is done using Automation Builder with a safety-certified editor.
  • TÜV certified Safety Code Analysis (SCA) tool opens the door to writing well-structured and easily understandable code which dramatically saves your time and money on solution certification efforts.

AC500-S Safety PLC range - extreme conditions XC modules

  • Applicable for harsh environmental applications like harbor cranes, mobile platforms, wind (offshore and onshore), etc.
  • Physical dimensions, basic electrical characteristics and software compatibility correspond with the standard AC500-S version.
  • Cost-savings in engineering and operation.


We provide a reliable and powerful platform to design and create scalable, cost-effective and flexible automation solutions. Our platform should be functional and operational - even under rough environmental conditions. Therefore we develop the eXtreme Conditions versions.

The benefits from the AC500 PLC platform like one Automation Builder engineering suite, I/O modules, scalability and flexibility, high performance communication, libraries and web services are combined with resistance to


  • High humidity
  • Salt mist
  • Vibration
  • High altitude
  • Hazardous gases
  • Temperature: from -40 to + 70 °C.

The AC500-XC range replaces expensive cabinets by its built-in protection against dirt, water, gases and dust. Many traditional practices such as HVAC for the panel, shock absorbers, door sealing etc. are not required. 

AC500-S Safety PLC range - extreme conditions XC modules 


  • Applicable for harsh environmental applications like crane, hoist, winch, robots, wind (offshore and onshore), solar etc.
  • Physical dimensions, basic electrical characteristics and software compatibility correspond with the standard AC500-S version.
  • Engineering and operations are much more cost-efficient since spending money on special cabinets and cabling practices can be avoided.
