AS-Interface

AS-Interface (ASi) is a globally standardized fieldbus system for the first level of automation. The abbreviation ASi stands for Actuator-Sensor Interface. ASi connects sensors and actuators with a controller via a single two-core profile cable. The yellow ASi cable transmits power and data at the same time. The main advantages of AS-Interface are, among others, dramatically less wiring, free choice of topology and cost-efficient integration of safety on the same infrastructure.

The latest ASi-5 generation can now handle larger data volumes at much higher transmission speeds and it enables intelligent sensors such as IO-Link to be integrated with ease.
