Product Introduction：
HS-3820-8S-SC-4GSFP is a 20 port (8 + 8 + 4) multi port rail type redundant Industrial Ethernet switch newly developed by Chengdu Huashu Communication Technology Co., Ltd. according to the actual needs of customers. It supports RJ45, SC / ST / LC and other interfaces. It adopts the high-end switching chip with the first market share in the industry. Its software and hardware functions are powerful, stable and reliable. Hs-3820 series can provide 8 10 / 100M Ethernet RJ45 ports, 8 remote Ethernet optical ports supporting SC / ST interface, and 4 Gigabit interfaces (SFP) for uplink data transmission or ring network application. It is very convenient to build a real-time industrial control network with high bandwidth and large data throughput. It supports IEEE 802.1Q VLAN, IEEE 802.1p QoS and other protocols, realizes the effective planning, management and monitoring of business data, and provides port mirroring, link aggregation, MAC address filtering, lldp and other means to effectively monitor and manage network data and network bandwidth. Support SNMPv1 / V2C / V3 and web server protocol, easily realize the remote setting, monitoring and management of various devices in the network. Support IEEE802.1d/1w STP / RSTP / MSTP protocol, improve the reliability of network topology construction, operation and data transmission. It supports the proprietary technology of super ring ring network, and two optional ports can form a high reliable and stable industrial Ethernet redundant ring network, providing a highly flexible, reliable and stable combined application for industrial equipment networking, data acquisition and transmission.
HS-3820 Series has redundant dual power supply DC input function with extremely wide voltage range (10 ~ 55v), which greatly improves the adaptability and reliability of power input and protects the reliable transmission of network data of industrial automation system. The device has relay alarm output port, which can be set flexibly and humanely, and has rich alarm output functions, such as power operation, optical and electrical port link, ring network main and standby link, etc. when there is power failure or optical and electrical port link, ring network main and standby link changes, the relay will quickly respond to output alarm signal, so as to timely inform the field personnel of maintenance Troubleshooting. HS-3820A Series products meet the FCC and CE standards, meet the industrial level 4 design requirements, support the normal operation under the conditions of wide temperature - 40 ℃ ~ 75 ℃, adapt to the harsh working environment conditions, meet the operation requirements of the industrial site, and provide a powerful means and network system solutions for the construction and operation of the customer's industrial real-time data network.
