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
