When you automate a process, sensors and actuators are always required. Whether it be in a lo-

gistics center, where light barriers check the position of a package on a conveyor belt, in a bev-

erage bottling plant where the liquid level is checked, or in a steel mill where beams have to be

cut at a precise position. Sensors – the eyes and ears of process control – are everywhere.

For a long time, these transmitters and transducers were cabled in the same old way: Each indi-

vidual sensor and actuator was directly wired to the higher-level control, resulting in complex

and messy bundles of cables with the associated electrical cabinets. In the mid nineties, with

the introduction of the AS-Interface®, bus technology – already a standard at the field and con-

trol level – established itself in the world of binary sensors and actuators.

A general standard was agreed on which was rugged and flexible enough to fulfill all of the re-

quirements of an industrial data bus. However, it simultaneously addressed the special require-

ments of the “lowest” control level. Now, process-related devices (sensors, actuators, and opera-

tor units) can be interlinked with one another and connected to industrial communication

systems – and that extremely simply and effectively.

In all of the automation technology, the AS-Interface is the simplest and most favorably priced

solution. As of now, there is no serious competition. With the backing of a strong international

organization as well as the leading manufacturers, AS-Interface will dominate the market, also

in the future.

This brochure addresses those interested in the AS-Interface as well as users and provides an in-

sight into the technology behind the AS-Interface and how it is used in the field.
