Phoenix Contact has expanded its portfolio of Radioline 2.0 Industrial Wireless Solutions with the addition of Radioline 900MHz Wireless System. The system joins Radioline 2.4 GHz, which was released last year. Radioline 2.4GHz and 900MHz lines extend industrial systems and networks for up to 250 devices. Whether I/O signals or serial data (RS-232 or RS-485), it is one wireless system for multiple applications, the company explains. The Radioline 2.4GHz can be used for applications with clear line of sight for distances up to 3.5 km, and Radioline 900MHz for distances up to 32 km.
