The PowerTrans PT-7828 switches are high performance Layer 3 Ethernet
switches that support Layer 3 routing functionality to facilitate the deployment
of applications across networks. The PT-7828 switches are also designed to meet
the strict demands of power substation automation systems (IEC 61850-3, IEEE
1613), and railway applications (EN50155/EN50121-4).
The PT-7828'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 and wiring costs. The
modular design of the PT-7828 makes network planning easy, and allows greater
flexibility by letting you install up to 4 Gigabit ports and 24 fast Ethernet
ports. Optional front or rear wiring makes the PT-7828 switches suitable for a
variety of applications.
