PowerTrans PT-7728-PTP switches are designed to meet the demands of
power substation automation systems (IEC 61850-3, IEEE 1613). The
PT-7728-PTP's Gigabit and fast Ethernet backbone, redundant ring, and
24/48 VDC or 110/220 VDC/VAC dual isolated redundant power supplies
increase the reliability of your communications and save on
cabling/wiring costs.
Moxa's PT-7728-PTP IEC 61850-3 fast Ethernet switches support the
latest version of IEEE 1588 v2 technology to fulfill precision time
synchronization requirements for protection and control applications.
These Ethernet switches guarantee time-stamping accuracy within 1 μs for
the IEC 61850 process layer. They can be configured for 1588 v2 Master,
Boundary Clock, and Transparent Clock functionality.
The modular design of the PT-7728-PTP also makes network planning
easy, and allows greater flexibility by letting you install up to 4
Gigabit ports, 24 fast Ethernet ports, and up to 14 IEEE 1588 fast
Ethernet ports. Along with a choice of either front or rear wiring,
these features together make the PT-7728-PTP suitable for a variety of
industrial applications.
