View : 639
Type : Managed Din Rail Industrial Switch
Description :

This product adopts an industrial rail design, it is a new generation of multi-service access network management gigabit redundant Ethernet switch.


This product adopts an industrial rail design, it is a new generation of multi-service access network management gigabit redundant Ethernet switch, which has the characteristics of high integration and rich functions. It has 8 gigabit electrical ports and 4 gigabit optical ports, especially suitable for occasions with large data streams such as video transmission.


It supports rich Layer-2 management protocols required for industrial switch applications, supports ITU G.8032 redundant ring network protocol, and forms cascaded, single-ring, tangent-ring networks and other topological structures. The self-healing time is less than 20ms, ensuring the real-time and stability of the network. The switch adopts mature technology and open network standards, and it can adapt to low and high temperature, it has features of anti-electromagnetic interference, anti-salt spray, anti-seismic and anti-shake, meets the harsh working environment requirements of industrial sites. It can provide efficient, reliable and quick solution for industrial Internet of Things.


managed 8 port gigabit ethernet switch


The switch features an aluminum alloy housing, an industrial rail design, good heat dissipation characteristics, a gold oxide process, and an IP40 protection level. It is specifically designed for harsh industrial environments.

It supports 8 Gigabit Ethernet ports, 4 Gigabit SFP optical ports, and optional 4-port RS485/232/422 or 3-in-1 serial ports.

Each ethernet or optical port supports the standard ERPS ring network protocol, with a self-healing time of less than 20ms.

It supports port bandwidth limitation, port traffic control, and broadcast storm suppression.

It supports Web, CLI, and Telnet management functions.

It supports power down alarm and loop alarm.

●  It supports POE (POE+) devices.

● Serial server function:

  ● Serial communication supports line speeds from 300bps to 921600bps with non-blocking communication. It supports automatic baud rate scanning and custom baud rates.

  ● It supports various operation modes such as Modbus TCP, TCP Server, TCP Client, UDP Server, and UDP Client.

  ● It transparently converts Modbus-RTU to Modbus-TCP, enabling serial device data to be accessed through the network.

  ● It supports monitoring of serial port status and parameters, providing clear communication status.

  ● It supports communication across gateways and routers, and it has features such as virtual serial port driver access mode and automatic reconnection after network interruption.

  ● It offers flexible serial data framing settings to meet various packetization requirements.

  ● It supports standard TCP/IP socket applications to access TCP with multiple connections, allowing up to four users to monitor or manage serial devices simultaneously.

  ● In UDP mode, it supports communication between a single host or multiple hosts, enabling multiple users to monitor or manage serial devices simultaneously.

  ● It supports various configuration methods, including Windows configuration tool, serial port, and web-based configuration.

● Management functions:

  It supports CLI, WEB, and SNMP management methods.

  ● It supports port-based ingress/egress rate limiting, half-duplex backpressure flow control, and 802.3X full-duplex flow control.
