| Abstract: | The actuator-sensor interface (AS-interface) has established itself as a system for networking primarily binary sensors and actuators at the lowest level of the automation hierarchy. The high number of installed systems, the ease of use and the reliable operating behaviour also make the AS-interface interesting in the area of machine safety. The safe AS-interface system is intended for safety applications up to Category 4 in accordance with EN 954-1. Mixed operation of standard components and safe components is possible. |
