Introduction
The PowerTrans PT-508 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, and 24/48 VDC or 110/220 VDC/VAC dual isolated redundant power supplies increase the reliability of your communications and save on switchescabling/wiring costs. In addition, the DIN-Rail and wallmount design of the PT-508 makes network planning easy, and allows greater flexibility by letting you install up to 8 fast Ethernet ports for power distribution applications.
