WLg-ACCESS-ATEX is designed for industrial applications in explosive environments like the chemical industries, refineries, electric stations, very dusty environments and also those where sparks and electric arcs occur.

It's network interface enables connection to any industrial equipments (PC, PLC, I/O, acquistion systems, displays...) to communicate through the wireless Ethernet network.

Thanks to its built-in WEB interface, the setup of the device is achieved using the web browser installed on your computer (Internet Explorer, Netscape, Mozilla....)

WLg-ACCESS-ATEX doesn't require any additional software to be installed in your computer (no peripheral driver needed).

WLg-ACCESS-ATEX work wth any kind of industrial protocols carried by Ethernet TCP/IP.
