ASi connects sensors and actuators with a controller via a single two-conductor profile cable. The yellow ASi cable transmits power and data at the same time.
The proven main benefits of ASi are, among others, dramatically less wiring, free choice of topology and cost-efficient integration of safety on the same infrastructure. In addition, compared to other fieldbus systems, ASi needs no connectors for data and power integration.
ASi-5 is the latest innovation stage of AS-Interface (ASi), a globally standardised fieldbus system for the first automation level.
