- Easy two-wire wiring system - High-performance controllers and gateways - Graphic display for convenient configuration and diagnosis - For use with different fieldbuses The actuator-sensor interface (AS-i) is a manufacturer-independent standard for the connection of actuators and sensors of the first field level. AS-Interface has become established as an economic wiring system in industrial automation. A two-wire flat cable transmits data and energy. This considerably reduces wiring complexity since conventional parallel wiring of each sensor or actuator to the controller is no longer necessary. It also saves the user a great number of terminals, splitter boxes, input/output cards and cable lines. AS-i gateways with integrated PLC function control the data exchange to the sensor/actuator level and communicate rapidly with the superior control level. They can be used as independent, decentralised controllers or as gateways to all common fieldbus systems. The range includes interfaces with EtherNet/IP, Profibus, Profinet, EtherCAT or CANopen.
