1) Line distance/line differential protection communication + binary signal transfer, optical multimode or
single-mode LC small form-factor pluggable transceiver (SFP)
The relay has a nonvolatile memory which does not need any periodical maintenance.
The nonvolatile memory stores all events, recordings and logs to a memory which
retains data if the relay loses its auxiliary supply.

Local HMI

The LHMI is used for setting, monitoring and controlling the protection relay and the
related process. It comprises a 7-inch color screen with capacitive touch sensing and
a Home button at the bottom of the LHMI.
The LHMI must be paired with the protection relay to enable all the
functionalities in it. See the operation manual for the pairing
procedure.
The LHMI is an accessory for the relay which is fully operational even
without the LHMI.
