Field of application

The RNO22 is a 1- or 2-channel output isolating amplifier 24 V DC with bidirectional HART transparency for digital communication with smart actuators. It 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. The compact interface device with up to two galvanically isolated channels enables open- and short-circuit monitoring for reliable operation of critical equipment.
