New NEMA 4X Wireless I/O Device

Phoenix Contact expands the Radioline product family

Middletown, Pa. – Phoenix Contact has added a new 900 MHz spread-spectrum transceiver to its award-winning Radioline product family. The RAD-900-DAIO6 (Outdoor Radioline) makes retrofit and expansion projects much simpler and faster by eliminating or supplementing signal wiring for conventional I/O signals.

This device can monitor digital on/off status, actuate relay outputs, and transmit or receive 4–20 mA signals over distances up to 20 miles. The I/O signals can be mirrored at other stations in the wireless network or mapped to Modbus RTU for easy integration into a Modbus host system.

A single network can support up to 250 radios with any combination of repeaters and slaves, and the RAD-900-DAIO6 is completely interoperable with the existing Radioline products. Basic configuration requires no software. Simply set the Radio ID using a thumbwheel on the front of the transceiver. The user can access advanced configuration and diagnostics with the free PSI-CONF software.

The RAD-900-DAIO6 can be powered with 10.8–30 V DC or 100–240 V AC, making it a perfect solution for remote monitoring applications with any available power source. The unique NEMA 4X packaging, coupled with the wide operating temperature range (-40 to +70 C) and Class I, Division 2 approval, is designed for use in harsh industrial environments and can be installed in minutes with standard hardware. 

The technology behind Trusted Wireless 2.0 provides robustness and dependability. Frequency-hopping spread spectrum (FHSS) offers redundancy and fail-over in time, frequency, and space, ensuring very high reliability even in the most challenging radio environments. Trusted Wireless also provides the intelligence required for roaming and self-healing network structures, while 128-bit AES encryption protects data. The result is a secure and reliable wireless network that installs easily with no specialized expertise, automatically adapts to changing environments, and can be expanded as needed.
