The PT-G7728 Series is a family of IEC 61850-3 Edition 2 Class 2 compliant, Layer 2, modular, managed switches, built to provide high reliability and flexibility in digital substations and mission-critical industrial automation networks. Designed with a hot-swappable interface and power modules, the series enables continuous operation even during hardware changes or upgrades, eliminating costly downtime.

Each switch includes four fixed Gigabit ports (2x copper, 2x SFP) and six interface module slots that can accommodate a wide range of LM-7000H series Ethernet and PoE+ modules. Up to 28 Gigabit ports are supported in total, allowing operators to configure an optimised port mix for substation, utility, or industrial requirements. Two hot-swappable power slots provide redundancy with wide-range supply options, including 24/48 VDC or 110/220 VAC/VDC, ensuring resilient operation across diverse field conditions.

Redundancy and resiliency are built in, supporting Turbo Ring v1/v2, Turbo Chain, MSTP, RSTP, STP, and link aggregation. Time-sensitive applications benefit from hardware-based IEEE 1588v2 PTP, including power profiles IEC 61850-9-3 and IEEE C37.238, providing precise clock synchronisation across protection and control systems.

The PT-G7728 Series also integrates a built-in MMS server based on IEC 61850-90-4 switch data modelling, enabling seamless SCADA integration. Advanced Layer 2 management features include VLANs, quality of service, IGMP snooping/querier, ACLs, and SNMPv1/v2c/v3, offering fine-grained control and monitoring of traffic flows.

Certified to IEC 61850-3 and IEEE 1613, the PT-G7728 withstands EMI, surges, vibration, and temperature extremes from -40 to 75°C. Combined with its modular design and hot-swappable flexibility, the PT-G7728 provides a scalable, standards-based foundation for building resilient, high-bandwidth substation backbones and industrial automation networks.
