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.
