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.
The modular design of the PT-7728 also makes network planning easy,
and allows greater flexibility by letting you install up to 4 Gigabit
ports and 24 fast Ethernet ports. Along with the optional front or rear
wiring, these features together make the PT-7728 suitable for a variety
of industrial applications.
