Introduction

The PT-G7728/G7828 modular switches provide up to 28 gigabit ports, including 4 fixed ports, 6 interface module slots, and 2 power module slots to ensure sufficient flexibility for a variety of applications. The PT-G7728/G7828 switches are designed to meet evolving network requirements, including a hot-swappable module design that enables you to change or add devices without shutting down your device. IEC 61850-3 28-port full gigabit modular managed Ethernet switches. The multiple Ethernet modules (RJ45, SFP, PoE) and power units (24/48 VDC, 110/220 VAC/VDC) available provide even greater flexibility as well as suitability for different operating conditions. The switches support a full gigabit platform that provides enough bandwidth to set up an Ethernet backbone. Certifications include IEC 61850 Edition 2 Class 2 to ensure high availability and wide usage.
