Trusted Wireless mod-ules from Phoenix Contact can also be employed for implementing safe and disturbance-free wireless solutions in potentially explosive sites. The certification given in accordance with Atex and IECE ensures that the unidirectional and bidirectional RAD-ISM-2400 wireless system and its expansion modules can be employed internationally in Zone 2 of the Ex area. The wireless link is established quickly and simply by means of the plug and play principle. For this purpose, the radio path between the transmitter and the receiver functions in Zone 1 and Zone 0, because the transmission power for these is below the limit necessary to ignite an explosive mixture. In this way, process engineering data, such as analog control signals and digital status and control signals, can be recorded in potentially explosive atmospheres and transmitted over a distance ranging between several hundred meters and several kilometres from the transmitter. They are then outputted one-to-one at the receiver.
