RB223
Loop powered passive barrier
One or two-channel barrier for the safe separation of 4...20 mA standard signal circuits
-
©Endress+Hauser
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.
Fordele
Compact side-by-side housing for DIN rail
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
Anvendelsesområde
Separation of active 0/4 to 20 mA signals from transmitters, valves and adjusters.
