Description
The RNO22 is a 1- or 2-channel output isolation amplifier 24 V DC with bidirectional HART transparency for digital communication with intelligent actuators. It is used to safely control active components such as control valves, actuators, I/P converters or display devices. The intrinsically safe device separates and transmits analogue signals 0/4 to 20 mA. The compact interface device with up to two galvanically separated channels allows for idle and short circuit monitoring for reliable operation of critical systems.

Features
Reliable control of active components such as control valves, current/pressure converters
Quick and easy wiring and start-up
Accurate and reliable signal transmission
Circuit breaker and short-circuit monitoring
