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 RNO22 output isolating amplifier is used to safely control active components such as control valves, actuators, I/P converters or indicators. The intrinsically safe device separates and transmits analog 0/4 to 20 mA signals and offers bidirectional HART® transparency for digital communication with smart actuators. The compact interface device with up to two galvanically isolated channels enables open- and short-circuit monitoring for reliable operation of critical equipment.
