Field of application

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.

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

Benefits

  • Space-saving one-channel and two-channel version

  • No power supply necessary

  • International Ex approvals; Can be used up to SIL 3

  • Bidirectional HART® transmission

  • Communication sockets for HART® + integrated HART® resistor for sensor configuration
