WLg-ACCESS-ATEX is a rugged equipment designed for industrial applications in explosive environment like the chemical industries, refineries, electric stations, very dusty environments and also those where sparks and electric arcs occur ... for material handling, real-time information transmission.
It fulfils the most severe requirements in terms of operating environment: extended temperature range, shockproof and vibration proof, IP66 seal rating for protection against dust and water projections, ATEX level EX II (IP66)
The WLg-ACCESS-ATEX used in the ACCESS POINT mode makes it possible to create an industrial WiFi wireless network from any industrial equipment featuring an 10/100 Ethernet interface.
Used in the BRIDGE mode, the WLg-ACCESS-ATEX enables to connect any industrial equipment featuring a 10/100 Ethernet interface to the WiFi wireless network.
WLg-ACCESS-ATEX module can also be used as a WiFi network repeater (WDS) in order to extend radio coverage, device supports both INFRASTRUCTURE and AD-HOC modes.
The WLg-ACCESS-ATEX device is also designed to work as a wireless bridge between the wired MODBUS/TCP or PROFINET protocols and the radio network, this feature allows to connect any MODBUS/TCP or PROFINET equipments to this 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).
The WLg-ACCESS-ATEX is compliant with the IEEE 802.11 b/g or a/h standards (wireless Ethernet), it features a built-in 2-port Ethernet 10/100 base TX auto-sensing switch.
The radio link is made safe by using most modern methods of protection: WEP 64/128 bits, WPA-PSK, WPA2-PSK and authentification IEEE 802.1x (RADIUS server).
The nominal range (open space) of the module is 300 m for a transmit power of +20 dBm and -92 dBm in reception (g mode) and -95 dBm (IEEE 802.11b mode).

Application examples
The WLg-ACCESS-ATEX enables to connect two Ethernet networks or two Ethernet equipments in the AD-HOC mode (direct radio connection without infrastructure) or within a radio network controlled by an Access Point as well.
The WLg-ACCESS-ATEX can also be configured to work as a WiFi access Point.
WLg-ACCESS-ATEX also supports the MODBUS/TCP & PROFINET protocols, thus you can easily replace a network cable by the radio link to connect any industrial equipment which rely on these protocols.
