Introduction
 
The PowerTrans PT-7728 is designed to meet the demands of power substation automation systems (IEC 61850-3, IEEE1613), 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 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. The optional front or rear wiring makes the PT-7728 suitable for a variety of applications.
