Introduction

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

                                                                      
Its network interface enables any industrial equipment (PC, PLC, I/O, acquisition 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 on your computer (no peripheral driver needed).

 

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