AS-Interface.
Safe, cost-saving automation.
The international standard for intelligent automation.
AS-Interface (Actuator-Sensor-Interface) stands for clever automation technology. Whereas in conventional parallel wiring each signal is individually connected to the controller, ASi prevents cable spaghetti:
using just a simple two conductor cable – the yellow flat cable – the ASi bus connects the full field level to the controller – while at the same time all the modules are provided with power.
ASi is a worldwide industry standard – with over 36 million installed nodes. Discover why AS-Interface is so simple, efficient and innovative, and all the uses this manufacturer-neutral bus has to offer!
Simple
to install, configure, operate and expand
Efficient
it’s rugged, noise immune, diagnostics-friendly and cost-effective
Innovative
just one cable is used for data and power, topology is freely selectable, highly compatible
Proven in industrial applications of all kinds
More and more companies from various sectors are profiting by automating their systems with AS-Interface systems. This open bus technology is widely used in industrial automation, material handling and machine engineering. Find out more information about how ASi is used in seven different sectors below.
Simple networking of field level systems with AS-Interface
AS-Interface is an economical system for the lower field level as well. It networks binary sensors and actuators using simple installation methods to connect them with the higher controller level. The technology is promoted and further developed by the AS-International Association user organization.
ASi cable
Conventional parallel wiring
Just one cable for data and power
Parallel wiring, the geometry of the flat cable also prevents polarity reversal.
Simple cable piercing technology
Secure and errorless installation of the components is possible without any training. The installation cost and effort are markedly reduced. ASi modules are also easy to add and move.
Free choice of topology
The AS-Interface network topology is freely selectable and every ASi module can be installed at any position. For example, it is possible to configure star, ring or linear structures.
Continuous evolution of the ASi product world
AS-Interface products and components are continually being improved – including incorporating the new requirements of Industry 4.0. Today, E-STOPS aren’t the only things that are simple to connect and directly evaluate in the safety monitor. There are also numerous intelligent modules; including speed monitoring and motor control. You can find more information about the individual ASi components below, including links to examples of products and solutions from Bihl+Wiedemann.
