ASi Bus Termination

Profit from the variety of ways to extend ASi cable runs to 1000 m for example. Use the ASi Bus Termination, ASi Tuner and ASi Repeaters to extend the range of the ASi network flexibly and cost-effectively.

Splitting into several Segments

  • Dividing the ASi cable into multiple 100 m networks with their own Master and own power supply or by using double masters
  • Short ASi cables minimize interference susceptibility
  • Retains all the advantages of a 100 m ASi network
  • Not possible without an upper bus system

Refreshing the signal using ASi Repeaters

  • Extending the ASi cable by up to 100 m using ASi repeaters
  • Heavily saturated EMC areas can then be bridged
  • ASi repeater causes a slight time delay in each telegram

Reflection signal attenuation using the ASi Bus Termination

  • Very simple and cost-effective solutions using ASi Bus Termination 
  • Possible network extension by up to 100 m
  • ASi network should be checked at commissioning using the Software for Diagnostics, Service and Release Measurements ( BW2902 )

ASi Cable

The yellow ASi cable represents the simplest connection technology and efficient power distribution. Discover how you can save around 68 % on wiring costs compared to round cable solutions.


The standardized fieldbus system AS-Interface (ASi) helps you drastically reduce your wiring complexity. You also benefit from free choice of topology and cost-effective integration of safety features on the same infrastructure.

ASi Repeaters Are Also Available in the Web Shop

Here you will find ASi repeaters for installation in the switching cabinet and in IP67 for cable extension up to 1000 m. They are best suited to meet more stringent EMC requirements.
