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

Benefits

S500 I/O modules offer robust, scalable signal handling for centralized and distributed applications – supporting analog, digital, and mixed signals. Designed for industrial durability and system flexibility.

Handles analog, digital, and specialty I/Os.

Easy expansion

Add up to 10 modules per rack – highly scalable.

Industrial robustness

Shock and EMI-resistant – designed for heavy use.

Precise signal control

High-resolution inputs and fast counters.

Distributed architecture

Supports remote installation over fieldbus.

LED diagnostics

Clear status feedback on all channels.
