RT430/434 is a GNSS clock referenced to GPS and GLONASS satellites, whose main
application is to be a source of temporal synchronization signals in different formats
and protocols to synchronize internal clocks of equipment and systems based on
digital processing.
With nanosecond time accuracy, the RT430/434 provides temporal synchronization
for applications as synchrophasor measurement, traveling wave fault location,
current differential protection operating over SONET and MPLS systems, and others.
The time synchronization protocols supported are:

PTP (Precision Time Protocol) according to IEEE 1588v2:2008;

PTP Profile for Power Utility Automation, in accordance with IEC 61850-9-3:2016
standard;

PTP Power Profile, in accordance with IEEE C37.238:2011 standard

NTP/SNTP;

IRIG-B004 (Demodulated);

IRIG-B124 (Modulated);

DCF77;

Serial Datagram;

Low frequency pulses, as PPS, PPM and others configurable options.
RT430/434 GNSS features a TCXO as standard internal oscillator for accurate free-
running time reference when not synchronized by satellite. Furthermore, it is free
from any internal battery, using a supercapacitor instead., negating environmental
concerns and avoiding the need for periodic battery replacement.
The RT430 is the first clock to offer Parallel Redundancy Protocol (PRP). Profit from the
high-availability, reliability, and security of your Ethernet network to distribute time
accurately and economically over the same network used on your digital substation.
The front display of the RT430/434 shows either local or UTC date and time,
considering the DST rules when defined by the user.
RT430 is available in different versions, depending on the features required in each of
the two Ethernet network interfaces, including PRP for both, and the quantity and
input voltage range of the power supplies.
Apart from the PRP, the RT434 has the same functions and protocols as RT430. The
RT434 versions depends on the features required by each of the two pairs of Ethernet
network interfaces, and the quantity and input voltage range of the power supplies.
The Cortecs from RT430 and RT434 demonstrate the available versions for ordering.
