611 series overview

Overview

The 611 series is part of ABB's Relion® product family. The 611 series protection
relays offer functionality within basic protection and control configurations. There are
product variants for feeder, motor, busbar and voltage protection applications. The
relays, characterized by their compactness and withdrawable-unit design, are
designed for most utility substations and industrial power systems including radial,
looped and meshed distribution networks that may also involve distributed power
generation.
The 611 series relays support the Edition 1 and Edition 2 versions of the IEC 61850
standard for communication and interoperability of substation automation devices,
including fast GOOSE messaging. The 611 series relays are able to use IEC 61850 and
Modbus® communication protocols simultaneously. The relays also support the
parallel redundancy protocol PRP and the high-availability seamless redundancy
HSR protocol. IEEE 1588 v2 is available for high-accuracy time synchronization in
all variants with an optional redundant Ethernet communication module.
