AS-Interface 
Overview 
The AS-Interface (actuator sensor interface, AS-i) is an open international standard for 
fieldbus communication between distributed actuators and sensors at the lowest control 
level.   
AS-i complies with the IEC 61158 / EN 50295 standards and was specifically designed for 
connecting binary sensors and actuators that comply with these standards. AS-i makes it 
possible to replace point-to-point cabling of the sensors and actuators by a bus line.
