SWITZERLAND – Switzerland-headquartered instrumentation and automation company Endress +Hauser has introduced new interface components for reliable power supply, switching and signal doubling in safety systems.  

The new RN Series are comprised of RN22: (RN42): Active/passive barrier; signal doubler, RLN22: (RLN42): NAMUR isolating amplifier, RNO22: Output isolating amplifier, RNB22: System power supply (single or redundant), and RNF22: Feed-in and error message module. 

Endress notes that 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.  

Additionally, the interface components are equipped with intrinsically safe signal processing and conditioning devices that ensure reliable power supply and safe operations in hazardous areas, establishing a trusted signal link between field instruments and the process control level. 

Moreover, 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 instrument and automation company further notes that a multi-platform T-connector bus system ensures fast and easy commissioning and interoperability with compatible interface vendors. 

Endress+Hauser pumps US$9m in India facility expansion 

Earlier, Endress+Hauser announced that it was planning to invest Rs 100 crore (US$9 million) to expand its manufacturing facilities in India.  

According to Narendra Kulkarni, Endress+Hauser India Managing Director, the expansion works will see the company build a new 60,000 square feet building in the existing campus located in Waluj Industrial area, Aurangabad.  

Kulkarni said the company has also drawn up plans for the second phase of expansion, which can entail an investment of Rs 300 crore over medium to long-term, depending on the market conditions. 

“In the second phase, the company is mulling a 50,000 sq ft construction on the same plot over the next five years. After the end of the second phase of expansion, the company would have used up 70 per cent of its 25-acre land parcel,” he said. 

Endress+Hauser has been present in Aurangabad since 2013 and is presently engaged in manufacturing temperature measuring products, system products like indicators and recorders in India. 

The expansion works being undertaken by its flowtec and automation divisions are set to further increase the company’s presence in Asia’s second-largest economy.
