| Introduction | Data sheets |
Fieldbus technology has become established in recent years alongside conventional field devices and field devices with HART support. The solutions from the Profibus Organisation or the Fieldbus FoundationTM are now used in the majority of new installations. Solutions with fieldbus barriers have largely replaced the FISCO installations. Fieldbus barriers, such as the R. STAHL field device couplers, are operated in Zone 1 or 2 on a non-intrinsically safe bus (often called power trunk) and can integrate both Ex i / FISCO field devices (Ex i FDC), Ex d / Ex m field devices (Ex e FDC) and simple digital and Ex i signals (digital I/O couplers). The bus is supplied with the necessary power for up to 32 field devices using a single power supply or redundant fieldbus power supplies.
Besides the new ISbus components for the FOUNDATIONTM fieldbus and Profibus PA , R. STAHL also supplies all-inclusive system solutions. These range from different types of field housing, made from plastic, stainless steel, or aluminium, and innovative solutions with Ex-plug connectors for the non-intrinsically safe fieldbus to complete system solutions for all different forms of field signal. Depending on the application and customer requirements, R. STAHL optimally combines the components and systems from the Fieldbus ISbus and remote I/O IS1 sectors to create the most efficient and low-cost solution.
