These records are stored in non volatile
memory. Therefore, there is no need
for internal battery monitoring or
maintenance.
Trip circuit monitoring

complete supervision circuits for breaker
trip and closing coils and circuits. These
supervision inputs monitor both the
battery voltage level and the continuity of
the trip and/or closing circuits, applying
current through those circuits and

three ports that operate independently.
Redundant ports are available for high
reliability applications:
Available protocols for rear port 1 and 2
are ModBus RTU, IEC 103 and serial DNP
3.0.
The third port is located in a removable
communications card. This plug-and-
play card can be easily changed in the
future as new standards arrive to the
market, thus providing a migration path
to the customer.
The protocol available for the third port
is DNP 3.0 over TCP/IP, UDP/IP, ModBus
