Industrial Frequency Hopping 900 MHz Serial (FCC), non-CE


Discontinued: No new product for sale. More Info

The RLX-IFH9S provides powerful and secure wireless serial communications and is well suited for demanding, long-range (up to 30+ miles) SCADA and other serial applications in tough environments. Operating in the license-free 900 MHz band, the RLX-IFH9S penetrates foliage and walls / ceilings better than higher frequency radios. With both RS-232 and RS-485 serial ports, serial protocols such as Modbus RTU, DF1, ASCII and DNP3 are supported. The RLX-IFH9S 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.

RLX-IFH9S radios are quickly and easily 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.
