Our Fundamental Selection instruments feature an extended 5-year warranty – a clear testament of our trust in their long-term reliability and performance.
Should a warranty case occur, you can count on a fast replacement process and minimal administrative effort – giving you peace of mind when it matters most and helping you keep your operations running smoothly.
Warranty terms apply
The extended warranty is subject to specific conditions. For full details, please refer to the locally applicable General Terms and Conditions (GTC), which can be found on the respective country page of our website.
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.
Separation of active 0/4 to 20 mA signals from transmitters, valves and adjusters.
