Industrial Frequency Hopping 2.4GHz Serial (ETSI), non-CE


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

The RLX-IFH24S provides powerful and secure wireless serial communications and is well suited for demanding, long-range (up to 5+ miles) SCADA and other serial applications in tough environments. Operating in the internationally license-free 2.4 GHz band, the RLX-IFH24S offers an alternative when 900 MHz radios cannot be used due to government regulations, band saturation, or customer preference.

With both RS-232 and RS-485 serial ports, serial protocols such as Modbus RTU, DF1, ASCII and DNP3 are supported. The RLX-IFH24S is user configurable as a master, repeater and remote radio and employs the 128 bit AES encryption algorithm approved by the United States government for top secret information.
