PT-7728 Series
Gigabit/Fast Ethernet Modules for the PT-7828
PT-7728 Series
Introduction
The PowerTrans PT-7728 is designed to meet the demands of power
substation automation systems (IEC 61850-3, IEEE 1613), traffic control
systems (NEMA TS2), and railway applications (EN50121-4). The PT-
7728’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.
