PROFIBUS Linking Device LD 800P

The Linking Device LD 800P is the interface between the PROFIBUS DP and the PROFIBUS PA.

LD 800P performs the following tasks:

  • Potential separation between the PROFIBUS DP and the PROFIBUS PA
  • Conversion of the RS 485 physical arrangement of the PROFIBUS DP to the physical arrangement based on IEC 61158-2 of the PROFIBUS PA
  • Adapting the PROFIBUS DP transfer rate to the PROFIBUS PA transfer rate of 31.25 kBd
  • Power supply of PROFIBUS PA stations over the bus line
  • Diagnostics via LEDs
  • Ensuring intrinsic safety if the PL 890 power link module with an intrinsically safe interface is used
