AC500-S S500 I/O modules

Safety I/O modules ensure secure signal processing. They are ideal for applications with emergency stops, guard monitoring, and zone control.

Certified protection you can rely on

All AC500-S I/O modules are certified to SIL3 and PL e standards – ensuring safe and compliant automation. Whether used centrally or remotely via PROFINET/PROFIsafe, they offer high performance and flexible integration.

 

  • DI581-S: Up to 16 (SIL2) or 8 (SIL3) digital safety inputs, fully protected and designed for long cable runs.

     

  • DX581-S: Combine digital safety in- and outputs in one module up to SIL3-certified channels.

     

  • AI581-S: Four fast analog input module with 14-bit resolution and SIL3 support for current signals.

     

  • TU582-S: Reliable spring-type terminal unit for clean, tool-free installation.

All modules are also available in XC versions – for extreme environmental conditions like vibration, cold, or humidity.
