Digital Expansion Module 80190-280-02-R

The 28/20 port full gigabit unmanaged industrial Ethernet switch adopts a high-strength IP40 protective shell and industrial grade EMC design, including four models: CRS3228-8TX, CRS3228-8FX, CRS3228-8SFP, and CRS3220. It is a layer 2 Ethernet switch independently developed by Shenzhen Xunji Technology Co., Ltd. The product provides 16 fixed 10/100/1000M adaptive Ethernet ports, 4 fixed 1000M SFP interfaces (optional 1000Base or 1000Base-T modules), and 8 optional 1000Base-X optical ports (default SC interface, optional FC, ST) or 8 10/100/1000M adaptive Ethernet ports or 8 1000M SFP ports (optional 1000Base-X or 1000Base-T modules). Based on industrial installation requirements, we provide a 1U standard rack mounted installation method. This product adopts fanless, low-power, industrial grade design, with a working temperature range of -40~75 ℃, which can meet the requirements of various industrial sites and provide a convenient Ethernet communication solution.
