R. STAHL HMI Systems has released the latest 4x8 HMI series. The explosion protected Panel PCs for zones ½ consist of a front module with the bright display, a second module containing a processor unit with a fast CPU (AMD Dual Core G-T56N or Intel Core i7-3517UE), and a large heat sink with massive ribs.
Due to the stack effect, display and processor module heat is dissipated via natural convection in ambient temperatures up to +65°C. Operation of the HMIs in extremely cold environments with temperatures down to -40°C is also possible with an optional integrated heater – no additional enclosures or external fittings required.
The seawater-proof sealed aluminium enclosures protect against humidity in line with IP66. The Panel PCs offer numerous state of the art functions for operating and managing tasks on drilling platforms including integrated cameras for video calls, RFID interface for access control systems, and various wireless communication systems (Bluetooth as well as intrinsically safe 802.11a/b/g/n WiFi capability).
Combining a bright multi-touch panel and a hardened glass screen, the HMIs feature a sunlight readable display and that remains glare free even in very strong ambient light. An integrated brightness sensor automatically adapts the display brightness to changing natural or artificial light conditions.
The HMIs come with Windows 7 Ultimate or Windows Embedded Standard 7. They are available with 15 in., 21.5 in. and 24 in. WU format screens. The compact units can be mounted in many ways, for example on ayoke, as a Rig Floor PC or with a VESA mount inside a container. IECEx and ATEX certificates have already been obtained. INMETRO, TR, NEC and CSA certifications are pending and due for completion in the first half of 2015.
