The intelligent self diagnostic fieldbus distributor (WAFD) can connect PROFIBUSPA equipment (such as pressure transmitters, differential pressure transmitters, temperature transmitters, and actuators) is connected to a self diagnostic fieldbus distributor (WAFD). Self diagnostic fieldbus distributor(WAFD)Can self diagnosePA
The connection and open/short circuit status of the main line, PA branch line, and PA equipment automatically isolates the faulty PA section, solves the communication interruption caused by PA section faults, and ensures the safe operation of the system.
Connection of on-site devices for PROFIBUS PA
• Automatic bus termination
• Isolate defective PA sections
After repairing the fault, connect the isolated PA section

Expand PA section during operation
PA main line uses 2 cable entry glands
4 PA field devices use 4 cable entry glands
Connect PROFIBUS PA main line and PA branch line through cage spring method
Reverse polarity protection connection
• Diagnose through LED
• Powered through PA bus
Tighten the inlet cover on the bottom layer, or install an adapter on the assembly guide rail
• Protection level IP66 |
