12. Non-volatile memory
With non-volatile memory, relay retains fault data,
even after auxiliary power failure. The relay is
inherently reliable and features excellent immu-
nity to external electromagnatic interference.
13. Communication
The relay is available with optional communica-
tion feature. Modbus RTU protocol is supported
on RS-485 bus with four wire connection. This
allows relay to connect to control and monitoring
system through serial communication for remote
monitoring.
