RIO600 is a remote I/O unit designed to expand the digital and analog I/O of ABB’s Relion® series protection relays and to provide I/O for the station automation device COM600 using IEC 61850 communication. The unit allows maximum I/O flexibility and provides seamless IEC 61850 connectivity between the substation binary and analog signals.
One of the benefits with RIO600 is that it helps simplify and decrease the wiring inside the substation. In a traditional, fully hard-wired medium-voltage switchgear/substation control and protection system, you find extensive I/O wiring. The RIO600 unit, however, provides these additional inputs and outputs distributed within the switchgear itself.
RIO600 uses the Ethernet-based IEC 61850 for horizontal GOOSE communication. The signals can be transmitted within the switchgear and to the higher-level automation systems. Similarly, signals from the upper-level automation systems can be executed to RIO600 through connected protection relays. It also provides connectivity to Modbus TCP-based communication, which is widely used in different applications.
For grid automation applications, RIO600 offers Fault Passage Indication (FPI) functionality. RIO600 enables accurate current and voltage measurements from the medium-voltage network utilizing ABB's light weight sensor technology. Based on the measured values, RIO600 gives directional fault passage indication and reports it to the upper level system. RIO600 also enables power flow and power quality monitoring.
Thanks to its modularity you can install the RIO600 user-specific module configurations as required per application in the power system. The unit offers full flexibility as one device can contain up to 40 inputs or outputs and it can have different types of modules in its stack. RIO600 is designed on an industrial hardware platform and provides the same thoroughly tested reliability, performance and real-time functionality as ABB's protection relays.
