Application / Function

Application The RB223 isolator 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

Function The passive isolator transmits signal circuits from the input to the output by galvanic isolation. A HART® signal is also transmitted. The device is optionally available with intrinsically safe input/ output. The device is loop-powered and does not need any additional supply voltage of its own.
