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.
Application Example
a) Ex area
b) NonEx area
c) Valve, actuator, display
d) Active
e) Passive
f) Process transmitter
g) 2-wire device (sensor, actuator)
h) 4-wire device (sensor, actuator)
i) Power supply
- Transmission from non-Ex to Ex areas e.g for active adjusters,
