FGR2-IO Series

900 MHz Remote I/O Solutions

Companies turn to FreeWave for I/O wireless solutions that are rugged, easy to use, flexible, and cost-effective. Our I/O portfolio, including the FGR2-IO Series, drives wireless industrial operations and provides the foundation for process automation and savings.

FGR2-IO radios are available as standalone board-level or enclosed devices, as well as in an expandable format to meet any wireless I/O need. All models can operate in one of two modes: Modbus and Wire Replacement. In Modbus mode, all radios can be directly connected as an I/O peripheral to a SCADA network. For wireless replacement mode, FGR2-IOS and FGR2-IOE can operate as a slave connected to an FGRIO-M master.
