Pepperl+Fuchs Podcasts


Pepperl+Fuchs’ TechTalk helps listeners gain an insight into modern automation technologies by focusing on AS-Interface (Actuator Sensor Interface) and its associated safety technology, Safety at Work. TechTalk covers topics that range from hardware selection to installation and maintenance. Control engineers familiar with AS-Interface will get the latest news on specification enhancements, hear about new products, and familiarize themselves with established and cutting-edge troubleshooting methods, tips, and tricks.  Users who are interested in applying these technologies will learn what it takes to set up an AS-Interface system, how Safety at Work improves safety systems, and why those technologies have the potential to save time and money during all phases of a project.

AS-Interface power supplies are designed to power the connected devices and allow safe and fast AS-Interface communication.  Every now and then, the term Power24 comes up.  Tim explains how AS-Interface power supplies are different (compared to conventional 24 VDC power supplies) and what Power24 really means.

  • --AS-Interface power supplies operate with 30.5 V.  Consequently, AS-Interface devices do not need expensive DC-DC converters
  • --Integrated decoupling enables communication and power on the same 2-conductor cable
  • --Power24 is a limited specification with reduced segment length; decoupling is still necessary
  • --Large installations can take advantage of decoupling inside the gateway
