interoperability of substation automation devices.
The relays feature draw-out-type design with a variety of mounting methods, compact size
and ease of use. Depending on the product, optional functionality is available at the time
of order for both software and hardware, for example, autoreclosure and additional I/Os.
The RER620 relays support a range of communication protocols including IEC 61850
with GOOSE messaging, Modbus
