AS-Interface Products

IDT’s AS-Interface products are used as a part of a master or slave node and work as an interface to the physical bus. The devices realize power supply, physical data transfer and communication protocol handling. All products are fully compliant with AS-Interface Complete Specification V3.0.

About the AS-Interface

AS-Interface (Actuator Sensor Interface) is a bus system for low level field applications in industrial automation. The primary application is communication with small binary sensors and actuators using the AS-I standard. IDT’s AS-Interface (actuator sensor interface) products fulfill all requirements of the latest AS-I standard V3.0, defined by the AS-Interface Association, and will give you quick access to the world of AS-Interface.

The AS-Interface modernizes automation systems effectively, saving installation costs and time. The easy "plug and play" capabilities of AS-Interface products will minimize maintenance costs. A significant feature of AS-Interface is the "Yellow Cable." The 2 wires in the AS-I cable transmit power and data to all points in the network. To transform the binary data in the physical layer of the AS-Interface, highly integrated circuits are required. The AS-Interface is an open standard based on IEC 62026-2 and EN 50295.
