Field of application
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.
1- or 2-channel output isolating amplifier
Reliable control of active components such as control valves, current-to-pressure transducers
