Phoenix Contact Radioline Products

The Radioline wireless platform from Phoenix Contact offers wire replacement for simple 0/4 - 20 mA, Digital, RTD and serial communications. With software-free radio setup, Radioline offers a cost effective wireless solution where it is too costly or not possible to run wire.

Radioline features simple I/O to I/O communication without the need for programming software. More advanced configurations, such as high-speed serial communication, network topologies up to 250 nodes, nonintrusive diagnostics and 128-bit AES encryption, can be accessed via the free programming software. Radioline is available in two variants, 2.4 GHz and 900 MHz, allowing for applications to span distances from a couple hundred feet to several miles.

Advantages and Features:

  • Easy startup of wireless systems without programming
  • High degree of reliability – Trusted Wireless 2.0 technology, AES encryption, frequency hopping method, and coexistence management
  • Range of up to several miles
  • Save on devices: Transmit I/O signals or serial data using a single device - with the integrated RS-232/RS-485 interface
  • Set the address on the wireless module by simply turning the thumbwheel - no programming
  • Can be extended with up to 32 I/O modules – DIN rail connector and hot swappable design
  • Create a modular wireless station in the control cabinet and extend or replace it easily during operation
  • Distribute and multiply I/O signals freely
  • License free
