Profibus Couplers

Profibus DP Repeater(Bridge Coupler))

Profibus DP to DP Coupler(Protocol Repeater)

Profibus DP repeater is a kind of protocol conversion repeater, which can provide BUS isolation.The module can be used independently, it can replace 6ES7972-0AA01-0xA0,it can prolong the transmission distance,increase the BUS nodes and bridge different networks.

Functions and Characters

  • It does not require a configuration, the application is simple and convenient
  • RS-485 interface,in compliance with EN50170 Part 1
  • Support bus rates 9.6kBit/s, 19.2kBit/s ,45.45kBit/s, 93.75kBit/s, 187.5kBit/s, 500kBit/s;1.5MBit/s, 3MBit/s, 6MBit/s,12Mbit/s.Auto-sensing baud rates.
  • Can be connected in a multi-drop BUS way,32 pieces can be connected together in a BUS line.
  • Isolation:1.5KV
  • Power is DC12 to 30V 
  • With failure alarm relay output
  • 6 double color LED indication module current states
