RN Series: Reliable signal processing and conditioning
New interface components for reliable power supply, switching and signal doubling in safety systems
The RN Series interface modules power the foundation of measurement instrument loops and safety instrumented systems built on the widely used analog process control infrastructure. The intrinsically safe signal processing and conditioning devices (up to SIL 2 (SC 3) in accordance with IEC 61508) ensure reliable power supply and safe operations in hazardous areas, establishing a trusted signal link between field instruments and the process control level.
Benefits
Intrinsically safe signal processing and conditioning devices certified up to SIL 2 (SC 3)
Smart integrated safety features such as NAMUR signal conversion and line fault monitoring
Compatible with multi-platform DIN rail bus connector system, ensures fast and easy commissioning and interoperability with compatible interfaces
Tried and tested to seamlessly complement Endress+Hauser 2- and 4-wire (4 to 20 mA) instruments
Signal doubling safely opens a second channel for the process optimization domain without affecting the traditional automation system (in accordance with NAMUR NE 175)
Compact housings for efficient use of space in control cabinets
Easy selection, supply, installation, commissioning, troubleshooting and service
Smart power
Smart functions such as NAMUR signal conversion, line fault monitoring, galvanic signal isolation, signal doubling, output signal amplification with bidirectional HART transparency give operators control and flexibility in systems of any scale, protecting assets and safeguarding data signal integrity in the process.
The RN Series at a glance
Typical application scenarios
2- and 4-wire (4 to 20 mA) instruments (e.g. Cerabar PMP71, Proline 200/300, ModuLine TM131, …)
RN22 active barrier, sensor supply with HART transparency
Data managers (e.g. Memograph M RSG45)
RN22 signal doubler
Point level switches (e.g. Liquiphant FTL51)
RLN22 or RLN42 NAMUR isolating amplifier
Active components (e.g. control valves, actuators)
RNO22 isolating output amplifier
RNB22 230 V/110 VAC to 24 VDC system power supply
RNF22 Feed-in & error message module, redundant power supply
Seamless system integration
All RN Series interface modules perfectly integrate with Endress+Hauser instruments, and work equally seamlessly with instruments from other vendors. The compact, space-saving housings with up to two channels on 12.5 mm are plug-and-play ready for standard DIN rails and control cabinets.
Independent of the industry, our offering promotes simplicity every step of the way: from easy selection and supply, to installation, commissioning, troubleshooting and service at all stages of the life cycle.
