Touch enable operator panels.

R. STAHL HMI Systems provides a line-up of highly robust touch-enabled operating devices developed for efficient, direct operation and visualisation of applications in hazardous areas.

Certified for zones 1 and 21, the ET-208 Operator Interfaces with 7-inch widescreens and a hardened glass front feature front-side IP69 protection. This makes them cleanroom-suitable according to FDA requirements, because their operating front can be cleaned with a pressure washer. The HMIs come in a V2A stainless steel enclosure.

They are corrosion-proof, certified according to ISA-S71.04-1985, severity G3, according to EN 60068-2-6. Seawater presents no problem, either. Highly versatile for universal applications, they can be operated in ambient temperatures ranging from -40 °C to +65 °C. The luminous display and an antireflection coating ensure good readability outdoors in strong daylight.

The HMIs are equipped with interfaces for Industrial Ethernet and RS-422/RS-485, and optionally offer WiFi capability as well. A powerful Cortex A8 processor ensures fast data processing. In the standard configuration, the IP69 grade devices feature the Windows Embedded Compact 7 operating system. R. STAHL’s proprietary SPSPlusWIN software can be used to flexibly create and edit screens, process connections and messages for the HMIs.

• Stahl products are marketed in Ireland by Douglas Controls & Automation.
