Introduction
The PowerTrans PT-508 Series is designed to meet the demands of power substation automation systems (IEC 61850-3, IEEE 1613). The PT-508’s optical fiber Fast Ethernet backbone, redundant ring, redundant power inputs (24 VDC or 48 VDC), and isolated power inputs (24 VDC, 48 VDC, or 110/220 VDC/VAC) increase the reliability of your communications and save on cabling/wiring costs. In addition, the DIN-rail and wallmounting design of the PT-508 switches simplify network planning, and allows greater flexibility by letting you install up to 8 Fast Ethernet ports for power distribution applications.
