Industrial Frequency Hopping 2.4GHz Ethernet


Discontinued: No new product for sale. More Info
Recommended replacements: RLX2-IFH24E

The Industrial Frequency Hopping 2.4GHz series of radios provide powerful and secure wireless Ethernet and serial communications. They are well suited for demanding, long-range (up to 15+ miles) SCADA and other Ethernet applications, including those in harsh or hazardous environments. Operating in the internationally license-free 2.4 GHz band, the RLX-IFH24E offers an alternative when other wireless technologies cannot be used due to government regulations, band saturation, or customer preference.

The RLX-IFH24E is user configurable as a master, repeater and remote radio. It provides virtual peer-to-peer packet switching and network optimization using advanced Smart Switch technology. Combined with an industry leading high-speed transmitter, the RLX-IFH24E is ideal for applications requiring fast and reliable communications at long distances.

The RLX-IFH24E is quickly configured using the included, graphical ControlScape software. An OPC server software is also included and allows users to monitor radio network health with any OPC client based HMI software.
The RLX-IFH24E employs proprietary frequency hopping algorithms and 128 bit AES encryption algorithm approved by most governments for critical networks.
