One or two-channel barrier for the safe separation of 4...20mA standard signal circuits
- 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.
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.
