The RFI-MSIO from RF Innovations  is a Modbus capable low cost SCADA unit ideal for use with data radios in remote telemetry applications. The unit is compatible with Modbus RTU devices and ready to use with RF Innovations data radios for a complete wireless monitoring solution.

The unit provides access to analog and digital inputs and outputs in a simple ready to use package with no need to program. The RFI-MSIO can be used as a Modbus Slave in point-to-multipoint networks, or as a Modbus Master in a point-to-point mode. The point-to-point mode provides simple transfer of the available inputs and outputs, and when used with RFI data radios, provides remote transfer over a number of kilometers.

The unit includes a number of features important to reliable operation over data radio networks including message retries and watchdog monitoring for health of the communications. The unit also has a physical relay output for the watchdog output so connected systems can switch to fallback mode in the event of communications loss.

The unit is suitable for large scale Modbus SCADA systems as it provides an easy to use alternative to remote PLC slave units.
