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 (VAN-115/230AC-K27) and repeaters for AS-Interface -- Power supplies are important.  Fortunately, selecting them is fairly straightforward when considering a couple of specification parameters.  AS-Interface Repeaters are typically used to extend the total length of a network.

  • --Select the AS-Interface power supply to match your available input voltage.  When fusing the input side, take a look at the total current consumption of the supply
  • --Output current specifies how much current can be provided to power modules, the gateway, and possibly, a repeater
  • --AS-Interface power supplies are primarily designed for AS-Interface.  Thus their secondary voltage is fixed at 30.5 V
  • --Just as with the gateways, make sure they are mounted such that they are properly vented to keep the operating temperature within the specified range
  • --Repeaters are easy to use. They are bi-directional ... but watch out when using a repeater with a terminator
