I/O Expansion

The FreeWave Technologies IO Expansion Module offers a scalable solution to meet the demands of your automation requirements. The IO Expansion Module may either be stacked on an applicable IO radio or can serve as expandable remote IO modules through a serial connection. Regardless of the configuration, up to 15 modules may be stacked on the radio or base module. The IO Expansion Module is Class 1 Division 2 UL approved and adds significant flexibility to an existing Modbus IO network.
