Overview

The PT-G7728 Series 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 Series is designed to meet evolving network requirements, featuring a hot-swappable module design that enables you to change, add, or remove modules without having to shut down the switch.

Multiple types of interface modules (RJ45, SFP, PoE, PRP/HSR) and power units (24/48 VDC, 110/220 VAC/VDC) provide even greater flexibility to suit different operating conditions. The PT-G7728 Series complies with the IEC 61850-3 Edition 2 Class 2 standard to ensure reliable data transmissions when the device is subjected to high levels of EMI, shock, or vibration.
