Fieldbus Solutions - STAHL - #12

Today, differing applications and diverse customer requirements lead to simultaneous use of several fieldbuses. In addition, mechanical concepts matched to the tasks and ambient conditions are required. R. STAHL, together with its customers, plans selection of the components, bus systems and field-compliant housings. This means that we are able to supply the optimum all-in solution for the interface between field devices and automation system: for conventional sensors and actuators, for HART field devices and for fieldbus devices, and for any combination of them. Figure 1 shows a typical Zone 1 field station by way of example. The Remote I/O System IS1 of R. STAHL is fitted for cost-cutting connection of all conventional sensors/actuators. Unrestricted communication with HART devices is also possible. The IS1 system offers several options for this. Corresponding couplers connected via the fieldbus directly to the automation system are fitted for connection of field devices, H1 or PA. This means one field station for all applications.
