The ENDRESS+HAUSER 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.
Smart and compact
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. 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.
