IES618-4D Series

8-port Managed Industrial Ethernet Switch with 4 Serial Ports

  • Support 4 serial ports, 4 100M copper ports, 4 fiber or copper ports optional
  • Adopt SW-Ring patent technology, support single ring, coupling ring, chain, Dual-homing network function
  • Support redundant 12~48VDC power supply input, non-polarity, reverse connection protection
  • Support -40~75℃ wide operating temperature range


IES618-4D series are layer 2 managed industrial Ethernet switches with 4 serial ports. This series include six types of products and provide 100M copper port, 100M fiber port, RS-232, RS-485 ports, which can meet the requirements of different application scenes.

Network management system supports various network protocols and industrial standards, such as STP/RSTP, 802.1Q VLAN, QoS, IGMP Static Multicast, Port Trunking, Port Mirroring, etc. It also possesses complete management functions, including Port Configuration, Port Statistics, Access Control, Network Diagnosis, Rapid Configuration, Online Upgrading and so on. Each serial port supports 4 TCP or UDP session connections, TCP Server and other serial port operating modes. Moreover, it supports CLI, WEB, Telnet, SNMP and other access modes. It can provide users with good experience via friendly design of network management system interface, simple and convenient operation.

DIP switch can instantly restore factory defaults and achieve product upgrading. When power supply or port occurs link failure, ALARM indicator will be bright and send out alarm, meanwhile, alarm device connected to the relay will send out alarm for rapid scene troubleshooting. Hardware adopts fanless, low power consumption, wide temperature and voltage design and has passed rigorous industrial standard tests, which can suit for the industrial scene environment with harsh requirements for EMC. It can be widely used in smart grid, rail transit, smart city, safety city, new energy, aerospace, intelligent manufacturing, military project and other industrial fields.

Features and Benefits

  •  SNMPv1/v2c is used for network management of various levels
  •  Port mirroring can conduct data analysis and monitoring, which is convenient for online debugging
  •  QoS supports real-time traffic classification and priority setting
  •  File management is convenient for rapid configuration and online upgrade of the device
  •  Port statistics can be used for the port real time traffic statistics
  •  User password can conduct user hierarchical management to improve the device administrative security
  •  Relay alarm is convenient for troubleshooting of construction site
  •  Storm suppression can restrain broadcast, unknown multicast and unknown unicast
  •  VLAN can simplify the network planning
  •  Port trunking can increase network bandwidth and the reliability of network connection to achieve optimal bandwidth utilization
  •  Bandwidth management and flow control can reasonably distribute network bandwidth, preventing unpredictable network status
  •  Static multicast can be used for filtering multicast traffic to save the network bandwidth
  •  SW-Ring and STP/RSTP can achieve network redundancy, preventing network storm
  •  Support multiple serial port operating mode: TCP Server, TCP Client, UDP, TCP auto, Realcom, advanced TCP Server and advanced UDP
