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 Safety modules -- In this episode, Tim explains how to read a data sheet for an AS-Interface safety input module.  Specifically, he is talking about a VAA-2E1A-G10 style device with two safe inputs and one non-safe conventional electronic output.

  • --The operating voltage and why it is important
  • --The rated operating current includes the current needed to run the module plus the maximum current for the non-safe output
  • --This particular module is designed for mechanically safe contacts.  This is related to the contact testing
  • --'Dynamic data bits' indicate that the input data is used to send the dynamic safety data
  • --Functional safety specifications are important parameters needed when evaluating the performance of the entire system where the module is used
