Product Description

TH-G5028 series are multi-port, high-standard Industrial Managed Ethernet Switch is a type of network switch that is designed for use in industrial environments. It features 28 ports, with some of them being Combo ports, which means that they can support either copper or fiber connections.

This provides flexibility for different types of network connections. This switch is also managed, which means that it can be configured and monitored for optimal performance. It typically supports advanced features such as VLAN, QoS, and SNMP management, and can also support protocols such as RSTP and MSTP for redundancy and fast recovery in case of network failures.
