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 Ex area supply voltage of its own.
Application Example
a) Ex area
b) Non-Ex 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
