The intrinsically safe keyboard made of stainless steel is approved for the POLARIS SMART HMI 7″ W for zone 1/21 and for zone 2/22. It is connected directly to the intrinsically safe USB port. The keyboard can also be connected to the complete POLARIS series. The keyboard is completely made of stainless steel and has been developed for extreme industrial conditions (virtually insensitive to force), and its long-travel keys make it very comfortable to use. The keyboard is available in different languages.
