Weidmuller Industrial Wi-Fi appliance packs up to 10 times that of commercial-grade wireless devices.

Weidmuller introduced a 2.4Ghz, Wi-Fi Industrial Ethernet device, designed for wireless connections in process/automation applications connecting to PLCs, DCS/SCADA, data loggers or field instruments with an RS232/485 or Ethernet port/interface. Built around the 802.11b/g standard, the company’s WI-MOD-E-G wireless Ethernet appliance has a throughput speed of up to 108Mbps. It features 400mW of transmit power, up to 10 times that of consumer/commercial grade wireless devices.

The unit can operate as a Wi-Fi router/bridge, access point/client and serial server (RS232/485). By attaching an I/O expansion unit to the device, a user can send or receive up to 16-digital or 8-analog signals and Ethernet (Wi-Fi) at the same time. In addition, the WI-MOD-E-G provides standalone Modbus Master-Slave functionality within the network, and with other modules in the system featuring DHCP automatic IP addressing capability. For security, the unit features WEP and WPA2 PSK encryption, MAC address filtering, IP filtering, password login and white/black list authentication.
