AS-Interface

AS-Interface portfolio

AS-Interface, short for Actuator Sensor Interface (ASi), is a simple and cost-effective wiring technology for sensors and actuators in the field. Both the power supply and the data transmission are carried out via a two-core, reverse polarity protected flat cable. ASi devices are connected simply and flexibly using piercing technology—without additional connectors and at any point along the flat cable.

AS-Interface Advantages at a Glance:

  • Cost-effective integration of decentralized IOs
  • Open to all common fieldbus protocols
  • Flexible connection along the flat cable using piercing technology
  • ASi network lengths of several hundred meters are possible
  • Complete topology freedom (star, ring, or line)

Gateways

ASi gateways are the bridge from AS-Interface to higher-level industrial networks. They control ASi communication and make the data available to the control systems in a structured manner. As an open standard, ASi supports many protocols such as PROFINET, EtherNet/IP, EtherCAT, and others. A modern web server offers the option of complete configuration and extensive diagnostics. The integrated REST API also enables innovative IIoT applications.

AS-Interface modules

Modules

ASi modules allow the connection of sensors, motorized drive rollers, or valves at field level. A variety of modules with IP20 degree of protection for control cabinet installation through to IP67 for direct installation in the field fit seamlessly into numerous applications.

Highlights:

  • The G10 series are the smallest ASi modules in the world with IP68/69K degree of protection
  • The G20 motor control modules enable the connection of motorized drive rollers and smart motors, and are also available as a stand-alone module with integrated ZPA logic
  • The small CB10 module can be flexibly integrated into boxes or used for panel mounting

Indication / Operation

In automation networks, operating buttons and stack lights are the central interfaces between man and machine. Due to the integrated ASi interface, the devices can be connected directly to the ASi network. In addition to non-safety-related operator button boxes, Pepperl+Fuchs also offers emergency stop buttons. The color and number of modular signal lights can be flexibly adapted to the application.

AS-Interface safety components

Safety at Work

AS-Interface offers secure data communication up to PL e/SIL 3. Safety components are especially easy to implement with AS-Interface and meet the latest safety requirements up to PL e (EN ISO 13849) and up to SIL 3 (IEC 61508/EN 62061). Even older AS-Interface networks can be quickly retrofitted with a monitor as a security network. This is due to the unique backwards compatibility. As a result, AS-Interface also ensures a high level of investment security for the future.
