TURCK has enhanced its interface module (IM) family with the FM approved IM21 rotational speed interface module, programmable via push buttons or using a PC—which simplifies device setup and saves installation time. The modules employ FDT/DTM software, together with PACTware, enabling users to efficiently set and save multiple application parameters. Boasting the same universal supply voltage and removable terminal design as current IM series models, the IM21 module quickly installs in new or existing systems. Its ease of use and high functionality facilitates sophisticated asset management, including trending and data logging of values. The IM21 module is also equipped with a dual-line transflective LCD display that promotes excellent readability, even in bright lighting conditions.
