AC500-eCo - CPUs

Based on the successful AC500 range, the extremely compact AC500-eCo PLCs offer the most flexible and economical configuration available, low-cost and straightforward servicing, and all requirements of a modern control system from small to demanding applications.

  • For over a decade, the AC500-eCo V2 has been a proven and reliable range of CPUs tested in the field, and it is well established on the market. It is succeeded by the new AC500-eCo V3 CPUs.
  • The AC500-eCo V3 CPUs are based on the same concept and footprint as AC500-eCo V2. They enhance the range with a larger memory, and more processing performance. The AC500-eCo V3 CPUs provide more onboard I/O channels and more scalability via option boards which extends the feature set while maintaining the footprint. Additionally, they include various fieldbus communication capabilities and connectivity to cloud applications with secure protocols.
  • ABB uses a standard IEC61131-3-based programming system for the entire AC500 family - you will be up and running in no time with Automation Builder engineering suite.
