The relay can send binary and analog signals to other devices

using the IEC 61850-8-1 GOOSE (Generic Object Oriented

Substation Event) profile. Binary GOOSE messaging can be

employed, for example, for protection and interlocking-based

protection schemes. The relay meets the GOOSE performance

requirements for tripping applications in distribution

substations, as defined by the IEC 61850 standard (<10 ms

data exchange between the devices).

For redundant Ethernet communication, the relay offers two

galvanic Ethernet network interfaces. A third port with galvanic

Ethernet network interface is also available providing

connectivity for any other Ethernet device to an IEC 61850

station bus inside a switchgear bay, for example connection of

a remote I/O. Ethernet network redundancy can be achieved

using the high-availability seamless redundancy protocol (HSR)

or the parallel redundancy protocol (PRP) or with a self-healing

ring using Rapid Spanning Tree Protocol (RSTP) in managed

switches. Ethernet redundancy can be applied to Ethernet

based IEC 61850 and Modbus protocols.
