Widescreen HMIs for hazardous areas are a future-proof solution to replace and upgrade existing 15 and 19 in. operating stations. The modern 22 and 24 in. HMIs increase operating and visualization comfort across the board. Their LED backlights generally ensure a more luminous display and better readability of images. Large screens also provide the required higher widescreen format resolutions. HMIs fully support possible future upgrades at control level while displaying process images of current systems in the usual way, without requiring any new engineering or configuration.
