Introduction

The 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 redundant ring, and 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 technology (IEEE 1588v2 PTP) 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 14 IEEE 1588 Fast Ethernet ports or up to 24 non-IEEE 1588 Ethernet ports and 4 Gigabit 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.
