A pioneering standard cannot just be replaced.
We tailor it for the future.

AS-Interface is the certified, decentralized and powerful feeder system that perfectly manages data communication on the actuator/sensor level in all areas of automation technology – minimizing acquisition and engineering costs at the same time. The new generation ASi-5 raises this standard to a new level.


The new ASi-5 standard links the commonly available actuators and sensors of the lower fieldbus level to the upper Ethernet-based level even more efficiently, flexibly, and reliably.

The facts prove this:


Data width





Connected Devices


Addresser APP


Furthermore, ASi-5 is a strictly deterministic system: Inputs and outputs can be prioritized up to 1.2 ms.


The result: considerably more design options, the possibility for larger stand-alone applications, and reduced overhead costs. Additionally, ASi-5 permits the cost-efficient reading of a larger number of inputs and outputs in one location.

In short: ASi-5 increases the system’s performance, while simultaneously reducing costs.
