S500 I/O modules

  • part of ABB AC500 PLC product range
  • ABB offers a wide range of configurable and scalable remote I/O modules for the most common industrial fieldbusses
  • the remote I/O solution with S500 consists of a communication interface and I/O modules
  • the smallest configuration can be just the interface module with the onboard I/O channels
  • the AC500 product range provides real-time performance with usage of the S500 EtherCAT interface modules CI511/CI512
  • for applications with axis interpolation and multi-axis control which require high performance and precision
  • the CI511/CI512 modules also provide a cam switch functionality allowing extremely fast and precise local reaction time for switching the I/Os in a desired sequence configured by cam tables in the module itself

You can choose and combine your needed type of connection:

  • central, using local I/O bus of CPU module
  • up to ten I/O modules can be connected to the CPU
  • decentralized periphery via fieldbus between CPU module and remote I/O modules
  • for each fieldbus slave, up to ten I/O modules can be connected
  • multifunctional approach: some modules cover a broad range of requirements, e.g. AI531 with 8 types of different signals in one module
