Introduction
The PT-7528 Series is designed for power substation automation applications that operate in extremely harsh environments. The PT-7528 Series supports Moxa’s Noise Guard technology, is compliant with IEC 61850-3, and its EMC immunity exceeds IEEE 1613 Class 2 standards to ensure zero packet loss while transmitting at wire speed. The PT-7528 Series also features critical packet prioritization (GOOSE and SMVs), a built-in MMS server, and a configuration wizard designed specifically for substation automation.
With Gigabit Ethernet, redundant ring, and 110/220 VDC/VAC isolated redundant power supplies, the PT-7528 Series further increases the reliability of your communications and saves cabling/wiring costs. The wide range of PT-7528 models available support multiple types of port configuration, with up to 28 copper or 24 fiber ports, and up to 4 Gigabit ports. Taken together, these features allow greater flexibility, making the PT-7528 Series suitable for a variety of industrial applications.
