The world’s first 7''wide screen HMIs for ATEX zone 1.

The world’s first operating devices with a 7" wide screen suitable for use in ATEX zone 1 from R. STAHL HMI Systems combine state-of-the-art, user-friendly equipment with a highly robust design. The virtually indestructible devices are ideally suited for visualisation close to machines in drilling rigs or in the vicinity of compressors, mixers, and centrifuges in machine building applications.

Their wide 15:9 format display provides an 800 x 480 pixel resolution. Powerful processors and a bright display technology ensure high-contrast, glare-free display of process information. A modern capacitive touchscreen allows for easy, comfortable control of all process sequences. The HMI systems are designed to provide high reliability during continuous operation even under extreme conditions: they can be operated around the clock for years at ambient temperatures between -40 °C and +65 °C, and nearly all over the globe. The vibration-resistant interfaces feature a hardened glass front and a seawater-proof metal housing that ensures IP66 protection.

Even during outdoor use with strong incident daylight, the full-colour 7ʺ displays remain easy to read, since an anti-reflection coating minimises glare and overexposed areas.

By default, the new SERIES 200 operator interfaces are equipped with the Windows Embedded Compact 7 operating system. Alternatively, they are available as OPEN VERSIONS, allowing for the use of third-party software and enabling customers to easily install their own programs. Moreover, mechanical engineers can continue to use the comfortable Windows project engineering software SPSPlusWIN to create and edit screens as well as process connections and messages. Projects from existing devices can be imported and adapted for further use.

Integration into virtually all major automation systems is supported. The units are connected via explosion-proof Ethernet ports for copper or fibre optic cables, standard serial interfaces, or an optional WLAN module. Apart from Ex zones 1 and 21, the multilingual devices are of course also suitable for use in zones 2 and 22. Standard regional certifications (such as NEC, TR, CSA, KCC, INMETRO) will follow soon.

Additionally, the SERIES 200 provides excellent compatibility with units from the widely established, proven FALCON series (ET-/MT-65, ET-75, and ET-125). The new line is mechanically compatible to the dimensions of the predecessor generation – either directly or with an adapter frame. This also applies to units with additional application-specific stainless steel or plastic push buttons. Users can therefore easily exchange previous models with monochrome displays for modern colour wide screen displays.
