WS2028E-4GS-24T Industrial Switch

28-Port Gigabit and Fast Ethernet Mixed Layer 2 Unmanaged Industrial Ethernet Switch

The WS2028E-4GS-24T series is a 28-port Gigabit and Fast Ethernet mixed Layer 2 unmanaged industrial Ethernet switch. There are six models in this series for selection, providing various interfaces such as Fast Ethernet electrical ports, Fast Ethernet optical ports, and Gigabit SFP slots. It supports single or dual power supplies with AC/DC power options and adopts a rack-mounted installation method, which can meet the requirements of different application sites.
The hardware is designed with a fanless, low-power consumption, wide-temperature, and wide-voltage structure. After passing strict tests that meet industry standards, it can adapt to industrial field environments with harsh EMC requirements and can be widely applied in industrial fields such as smart grids, rail transit, smart cities, safe cities, new energy, and intelligent manufacturing.

Interface Type: Supports 4 Gigabit optical ports (SFP slots) and 24 Fast Ethernet optical/electrical selectable ports

Input Voltage: 100 - 240VAC/DC, 24VDC, or 48VDC

Operating Temperature: Supports -40～75℃ Operating Temperature

Mounting Method: 1U Rack-Mounted Installation
