RIO600 Relion ® series Remote I/O unit
The RIO600 Relion Series Remote I/O unit is a device designed to extend digital and analog I/O of ABB’s Relion series of protective relays. It provides I/O for the substation automation unit COM600 by using IEC 61850 communication and grid automation applications. The device provides strong I/O flexibility and enables seamless IEC 61850 connections between switching and analog signals in the substation. One of the advantages of using the RIO600 remote I/O unit is that it helps simplify and reduce wiring inside the substation. However, these additional inputs and outputs provided by the RIO600 unit can be distributed directly within the switchgear. In grid automation applications, the RIO600 remote I/O unit provides fault channel indication (FPI) capabilities and also supports power flow and power quality monitoring. In addition, the RIO600 remote I/O unit contains web technology-based capabilities to access devices and processes within the substation through a web browser-based human machine interface (WebHMI). Therefore, the RIO600 remote I/O unit plays an important role in improving the efficiency of distribution networks and operations.
