R. Stahl introduces big-screen T-Ex HMIs for hazardous areas

October 24, 2010 - SCREEN-TEC T-Ex operating and monitoring systems from R. STAHL ensure increased plant safety and optimal access to process information in hazardous areas: the HMIs, which are equipped with 22" or 24" displays, provide a resolution of 1,680 x 1,050 or 1,920 x 1,080 pixels. They support the latest versions of process control systems from a wide range of manufacturers. The additional screen space facilitates complex visualisations, e.g. in large-scale plants, and enables the display of additional information – scrolling or switching between pages are therefore no longer required. All T-Ex displays are based on modern LED backlight technology: process images are displayed with a 350 cd/m² luminance and a 1000:1 contrast. The high contrast makes all process information easily and clearly recognisable for users, ensuring that the screen is eye-friendly. T-Ex terminals are ATEX- and IECEx-certified for Zones 1, 2, 21 and 22; further certifications are pending.The operating and monitoring stations are currently available as remote KVM solutions. KVM over IP, WLAN Thin Client and Embedded PC models will fol-low shortly. Data transfer is carried out by means of CAT7 or fibre optic cables – the latter allow for maximum distances of 10,000 m. Engineers can save costs by using the plant's existing wiring. The T-terminals are protected by slim stainless steel enclosures and require little installation space. The keyboard allows for ergonomic, stress-free use: the keyboard/trackball unit and the enclosure’s stainless steel surface form a smooth plane which provides IP66 protection.
