The remote I/O unit RIO600 expands the number of digital and analog inputs and outputs of Relion® protection and control relays as well as the substation management unit COM600, in both primary and secondary substations. In grid automation applications, RIO600 can be used for advanced fault passage indication, reporting the information further to the upper-level system for faster fault restoration.
SMU615 is a dedicated merging unit with a standard digital interface, making it possible to connect ABB sensors and conventional instrument transformers to the IEC 61850-9-2 LE-based process bus for extended interoperability of substation automation devices.
