R.STAHL’s compact IS pac Exi isolator system provides the entire, sophisticated functionality required for process automation in hazardous areas subject to the risk of gas and dust explosion. It offers solutions for all conceivable requirements made of point-to-point transmission of process signals. There is a device with one or two channels for all processes and standard applications. Stand-alone application on single DIN rails, group installation of 20, 30 or more devices, simple integration in automation systems, transmission of HART signals or use in SIL applications: always the same design with consistent operator procedures. This drastically simplifies your planning procedures and wiring. The consequence of this flexibility is an unrivalled level of economy and efficiency. The IS pac product family is rounded off by individual system solutions from R.STAHL for use in Zone 1 and Zone 21 and by module versions that can be used for electrical isolation of non-intrinsically safe signals. This landmark system has proven its worth during many years of operation worldwide.
