RT430/RT434
GPS Precision-Time Clocks
RT430/434 is a clock referenced to GPS
satellites. Offering a complete solution,
these clocks are the universal precision
time synchronization units, with an
extensive number of outputs which
supports many timing protocols, including
the DST rules frequently used on power
systems applications. In accordance with
IEEE 1588v2 Precision Time Protocol
(PTP), the RT430 and RT434 are capable of
providing multiple IEDs synchronization
with better than 100ns time accuracy over
Ethernet networks. Choose the RT430 in
Ethernet applications where IEC 62439
PRP redundant architectures are required,
choose the RT434 where three or four
electrical network ports are required.
Time Sync Flexibility
The RT430 and RT434 are equipped with
multiple connector types, from isolated
electrical ports to optical fibers. Mostly of
the channels can be individually configured
to generate the protocol needed, such
as IRIG-B004, PPS, DCF77 and freely
configurable low frequency pulses.
PTP in PRP Networks
RT430 offers the accurate Precise Time
Protocol (IEEE 1588 PTP v2) combined
with the Paralell Redundancy Protocol
(IEC 62439-3 PRP), ensuring 100 ns
accuracy and high-availability in time
synchronization over Ethernet networks.
In case of failure in one of the redundant
networks, the recovery-time is zero.
