Highlights

  • Input 2 x analog 4...20 mA
  • Output 2 x analog 4...20 mA
  • Bidirectional HART® transmission
  • Compact side-by-side housing for DIN rail

Fields of application

  • Separation of active 0/4 to 20 mA signals from transmitters, valves and adjusters.

Details

The RB223 passive barrier can be used to galvanically isolate active signal circuits (0 to 20 mA) in three applications:
Transmission from non-Ex to Ex areas e.g for active adjusters, controllers or indicators,
Transmission from Ex to non-Ex areas for connection of active, intrinsically safe circuits to the PLC,
Transmission from Ex to non-Ex areas for supply of intrinsically safe transmitters with non-intrinsically safe transmitter power supply.
