AS-Interface network – Basic principles

AS-Interface (Actuator Sensor Interface) is an international standard according to EN 50295 and IEC 62026-2 for actuator/sensor communication from AS-International Association e. V.

The AS-Interface offers the following advantages:

• Direct, simple connection of actuators/sensors or modules
• Data and power on a single two-core cable (unshielded cable)
• Any network topology
• Easy startup
• Optional external DC 24 V voltage supply for subordinate devices with increased energy requirements

• AS‑Interface master/AS‑Interface device
• AS‑Interface technology
• Network topology
• Addressing
• Extended ID1 code
