The FreeWave 900 MHz,  FGR2-IO Series provides outstanding performance and versatility in wireless transmission of process-control signals. FGRIO offers “transparent” acquisition, transport and reconstruction of analog, digital and power signals, eliminating the need for associated buried wiring.  The RTU requires no altered programming. The FGR2-IO Series is Class 1 Division 2 approved and is lower-cost and provides better signal integrity than vulnerable wiring. The FreeWave FGRIO-M master can be used for wire replacement networks, while the FGR2-IOS slave radio can be used for wire replacement and serial Modbus networks.
