Phoenix Contact Introduces RAD-WHG/WLAN-XD WirelessHART Gateway

Phoenix Contact’s RAD-WHG/WLAN-XD WirelessHART gateway features an integrated 802.11b/g WLAN transceiver that is rail-mounted. The 45 mm-wide RAD-WHG/WLAN-XD connects up to 250 WirelessHART field devices, converting HART data to Modbus TCP or HART UDP. The integrated WLAN can serve as the backhaul connection, allowing the gateway to be installed in the field closer to the monitored devices.

To maintain a secure connection, the gateway uses the 802.11i (WPA2) standard with 128-bit AES encryption to protect the WLAN data. The WLAN transceiver can also be disabled, and the host connection made via the wired Ethernet port. All programming and diagnostics can be accessed via an embedded web server. The RAD-WHG/WLAN-XD can also be programmed using a HART handheld programmer.
