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.The R. STAHL product range includes field device couplers for installation in Zone 1, Zone 2 and Class 1 Div. 2 for connection of e.g. I.S. or FISCO and non-I.S. fieldbus devices, simple discrete I.S. signals and more. The bus is supplied with the necessary power using a simplex or redundant power supply. Physical Layer Diagnostics is integrated as standard in the fieldbus power supply and can also be transmitted via FF H1 on asset management systems.
Besides the new ISbus components for FOUNDATIONTM fieldbus and Profibus PA, R. STAHL also supplies all-inclusive system solutions. These range from different types of field housings, 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 signals. 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.
