AS-Interface masters are a category of industrial automation products primarily associated with the AS-Interface (Actuator-Sensor Interface) standard, a global open network for connecting sensors and actuators. These products are developed by various companies, including leading industrial automation firms like Siemens (Germany), Pepperl+Fuchs (Germany), and Bihl+Wiedemann (Germany). AS-Interface masters serve as the central control units in AS-Interface networks, enabling efficient communication between sensors, actuators, and higher-level control systems (e.g., PLCs). They are widely used in manufacturing, process automation, and logistics industries for their simplicity, cost-effectiveness, and reliability. Key products include master modules, gateways, and power supplies compliant with the AS-Interface standard.
