AS-Interface: worldwide open installation standard

Advantages of AS-i: Higher performance. Less effort.

ifm’s AS-Interface (AS-i, ASI) opens up completely new possibilities for the user. From easy and quick set-up to additional data availability for machine monitoring to process transparency from the machine level to the PLC: AS-Interface offers convincing efficiency gains and cost savings. See for yourself!

Our customers who previously used standard parallel wiring see the following impacts:

15 - 30%
cost savings
through reduced installation complexity
20 - 50%
shorter installation times through considerable reduction of wiring and facilitated connection to the controller

Leading manufacturers of sensors, actuators and control technology have jointly developed AS-Interface. This creates a standardised and fieldbus-independent interface for automation, which offers the user a simple connection to control systems.

  • For use in harsh industrial environments and in wet areas up to IP69K
  • For functional safety up to PL e / SIL 3
  • ATEX II 3D / 3G

What does AS-i offer you?

  • A globally standardised system according to IEC 62026-2.
  • AS-Interface enables cabling while freely choosing your topology.
    It replaces the complex, conventional parallel wiring.
  • The cabling can be connected to control systems with different fieldbus systems (such as EtherNet/IP, Profibus-DP, Profinet, EtherCat etc.).

How do you benefit from AS-Interface?

  • Easy-to-implement, unshielded wiring and voltage concept.
  • AS-Interface is a flexible, inexpensive system that can be easily expanded.
  • Safe and non-safe data can be processed via the same system.
  • Less complex set-up and reduced input for documentation as well as diverse diagnostic capabilities.
  • Reduction of terminals through modular structure and flexible connection technology.

Bottom line

AS-Interface provides an easy and comfortable way to build a future-proof foundation for smart industrial automation.
