Phoenix Contact’s wireless I/O enables monitoring, control from multiple locations

Harrisburg, PA—To enhance its point-to-point two-way wireless device, RAD-ISM-900-BD-BUS for analog and digital signals, Phoenix Contact Inc. is introducing a bi-directional multipoint-to-point wireless I/O system, RAD-ISM-900-XD-BUS.


Harrisburg, PA— To enhance its point-to-point two-way wireless device, RAD-ISM-900-BD-BUS for analog and digital signals, Phoenix Contact Inc. is introducing a bi-directional multipoint-to-point wireless I/O system, RAD-ISM-900-XD-BUS.

The multipoint-to-point design gives users flexibility in bringing multiple channels of I/O from up to eight remote locations back to one master station. The bi-directional feature allows these devices to be used in monitoring and control applications, and eliminates cable and conduit for analog and digital signals in harsh industrial environments.

Phoenix says the addition to its wireless product line uses spread-spectrum, frequency-hopping techniques to guarantee a license-free, interference-free link between remote devices and the control room. Costly cable and conduit runs for many signals on new projects, or retrofitting of existing systems, are eliminated and replaced with a maintenance-free, reliable, versatile wireless solution.

Typical in-plant range is 600 to 1,000 feet with no line of sight, and much further in outdoor applications. The transceivers are powered separately with a 12-30 V dc source, such as a power supply, battery, or solar. Phoenix adds the process signals are quick and easy to install. They’re simply wired to the transmitters’ input terminals, and output via wires connected to the receivers. No wiring is required in between.

Both transceivers and I/O modules are featured in a slim, 22.5-mm, DIN-rail mount housing with integrated bus connection for communications and power. This allows them to be plugged into each other for easier installation. These devices offer diagnostic LED indicators for digital input/output signal status and radio link status and a radio signal strength indication (RSSI) port at each remote location.
