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

  • Transmission and galvanic isolation of 0/4 to 20 mA signals

  • Intrinsically safe [Ex-ia], installation in Ex Zone 2

  • Suited for use in safety instrumented systems up to SIL 2 (SC 3) in accordance with IEC 61508

  • Bidirectional transmission of digital HART® communication signals

  • Ambient temperature range: –40 to 70 °C (–40 to 158 °F)

Benefits

  • Safe and reliable control of active components in hazardous areas

  • Quick and easy wiring and commissioning: plug-in terminals, power supply via DIN rail bus connector

  • Compact housing: up to 2 channels on 12.5 mm (0.49 in) for efficient use of space in control cabinets

  • Accurate and reliable signal transmission

  • Line break and short-circuit monitoring
