MDS NETio Flexible I/O Signal Communications has three primary usages and transmits data in all three modes at the same time: Protocol Addressability, I/O Extension & IP/Ethernet and Serial Communications.

Protocol Addressability

NETio interfaces I/O from sensors and devices using multiple industrial protocols including Modbus-RTU, Modbus-TCP, and DNP3.

I/O Extension
NETio regenerates analog and digital signals between multiple field devices and controllers resulting in significant savings on wiring and termination costs.

IP/Ethernet and Serial Communications
NETio also supports IP/Ethernet and serial communication over long distances between SCADA systems and RTUs or PLCs.


The MDS NETio is an integrated, scalable family of wireless solutions that provide long distance, license-free communications, allowing users to interface both analog and digital I/O including sensors for pressure and flow as well as controls for pumps or alarms. NETio can wirelessly regenerate the I/O signals or use standard serial and IP/Ethernet protocols to communicate with controllers such as PLCs, RTUs and SCADA systems. 

Key Benefits

  • Direct connectivity to analog and digital devices without the need for a controller
  • License-free, long range communication of serial or IP/Ethernet data
  • Supports multiple industry-standard protocols including Modbus and DNP3
  • Reduces the high cost of wiring and termination fees
  • Reduces integration, configuration, and support costs found with multi-box solutions
  • Seamless connectivity to network access points
