Product Introduction：
HS-2820-8S-SC-4GSFP is a new 20 port (8+8+4) multi port rail non network redundant Industrial Ethernet switch 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 switch chip with the first market share in the industry. The software and hardware 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 thousand (100) megabits module for uplink data transmission. It is very convenient to establish a real-time industrial control network with high bandwidth and large data throughput. It supports IEEE 802.1Q VLAN, IEEE802.1p QoS and other protocols, and 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, and easily realize remote setting, monitoring and management of various devices in the network. It supports IEEE802.1d/1w STP/RSTP/MSTP protocol, which improves the reliability of network topology construction, operation and data transmission.
HS-2820 Series has redundant dual power DC extremely wide voltage range (10-55V) input function, greatly improves the adaptability and reliability of power input, and protects the reliable transmission of network data of industrial automation system. The equipment has relay alarm output port, and it can be set flexibly and richly with alarm output functions, such as power operation, optical, electric port link, ring network main and standby link, etc. in case of power failure or optical, electrical port link and ring network main and standby link change, the relay will respond to output alarm signal quickly, so as to inform the field personnel to maintain in time Troubleshoot. HS-2820 Series products meet FCC and CE standards, meet the requirements of industrial level 4 design, support normal operation under the condition of wide temperature of -40 ℃ ~ 75 ℃, adapt to the harsh working environment conditions, meet the operation requirements of industrial site, and provide powerful means and network system solutions for the construction and operation of real-time data network of customers.
