S500 I/O modules

Modular I/O modules support a wide range of signal types. They are suitable for both centralized control and remote I/O expansion.

Flexible I/O integration for every application

With S500 I/O modules, you can easily adapt your system architecture to project needs – whether centralized, decentralized, or multifunctional. Mix and match connection types to build exactly what your automation solution requires:

Central

Via the local I/O bus of the CPU module

Connect up to 10 I/O modules directly to the CPU

Decentralized

Using fieldbus links between CPU and remote I/O

Each fieldbus slave can host up to 10 modules

Multifunctional

Some modules, like the AI531. handle up to 8 different analog signal types in one device
