About BiSS Safety

BiSS Safety is a profile definition for the established BiSS Interface. It defines how to utilize BiSS C features for a secured communication in safety critical applications up to SIL3.

BiSS Safety offers functional safety features:

  • Safe point-to-point communication using BiSS C
  • Certified for safety critical applications up to SIL3
  • Fully compatible with all BiSS C features

Typical BiSS Safety Applications

  • Functional Safety
  • Rotary/Linear encoders for safety critical applications
  • Drives for safety critical applications
  • Communication monitors for safety critical applications


The BiSS Safety profile definition is certified by TÜV Rheinland and follows in extracts the requirements stated in IEC 61784-3:2021. It can be used in safety critical applications up to SIL3 according to IEC 61508:2010.
