Phoenix Contact offers explosion-proof, wireless I/O communications

Harrisburg, PA— Phoenix Contact reports that wireless I/O systems can now be safely installed in Division 1 areas by using its new XANT explosion-proof system. This patent-pending wireless I/O transmitter/receiver system features an Adalet cast-aluminum enclosure that houses a transmitter and antenna.

The system also includes a receiver and antenna, which are included loose with the packaged system, and can be housed in any of Adalet’s stainless steel or fiberglass enclosures. The rugged, aluminum enclosure is impact resistant to UL requirements, and includes an integral wire sealing chamber, eliminating the need for a field-installed, poured sealing fitting.

A second model, N4ANT, is also available for industrial or general-purpose, NEMA 4X-rated areas, where rugged protection is important.

Both models provide a wireless solution, which reduces installation labor costs, and eliminates the need for conduit and wires in hazardous or other industrial locations.

Phoenix Contact reports that these transmitter/receiver system uses spread-spectrum, frequency-hopping techniques to guarantee a license-free (902-928 MHz ISM band), interference-free link between remote devices and the control room. Typical in-plant range is 600-1,000 ft with no line-of-sight, but that range is much further in outdoor applications. Capable of carrying one 4-20mA analog signal, the systems also feature 1-W transmitter power and three contact outputs.
