RIO600 ABB remote I/O unit

Product details:

The RIO600 Remote I/O unit, dedicated to extending digital and analog I/O to ABB’s Relion® family of protected relays, provides I/O to the substation automation unit COM600 using IEC 61850 communications and grid automation applications.

The device provides strong I/O flexibility and enables seamless IEC 61850 connections between the substation switching and analog signals. One of the advantages of using RIO600 remote I/O units is that it helps simplify and reduce wiring inside the substation. In traditional, fully hardwired medium voltage switchgear/substation control and protection systems, you’ll find a lot of I/O wiring. However, these additional inputs and outputs provided by the RIO600 unit can be distributed directly within the switchgear.

RIO600

The RIO600 remote I/O unit provides fault channel indication (FPI) for grid automation applications. The RIO600 utilizes ABB’s lightweight sensor technology to accurately measure current and voltage in medium-voltage grids. RIO600 gives directional fault channel indications based on measurements and reports them to upper layer systems using Modbus TCP or IEC 61850. The RIO600 also supports power flow and power quality monitoring. High resistance transient and intermittent ground faults can be reliably detected even in compensation and isolation grids using advanced multi-frequency admittance (MFA) based ground fault indications.

The RIO600 remote I/O unit contains web technology based capabilities to access installations and processes within the substation through a web browser-based human machine interface (WebHMI). All standard substation monitoring can be handled using WebHMI.
