AC500-XC - S500 I/O modules

We believe expanding or adding field devices should be quite simply. Therefore we develop multifunctional and software configurable I/O modules and provide numerous basic I/O modules with different channels, signal voltage and fieldbus connections.

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.
