S8455I 4-Port Serial Device Server with Managed Ethernet Switch and Fiber Connectivity

Enhance your industrial networking infrastructure with the S8455I serial device server. Designed for harsh environments and mission-critical applications, this high-performance 4-port RS-232/422/485 device server features a built-in managed Ethernet switch and advanced redundancy protocols for seamless data communication and enhanced reliability.

Key Features and Benefits

  • 4 RS-232/422/485 Serial Ports: Connect a wide range of legacy serial devices to your network with flexible serial communication support.
  • Integrated Managed Ethernet Switch: Streamline your network by combining serial and Ethernet connectivity in one space-saving device.
  • Diverse Ethernet Port Options: Choose between S8455I fiber models with 2 multi-mode fiber ports and 3 copper ports, or all-copper models with 5 Ethernet ports to suit your network requirements.
  • Industrial-Grade Performance: Operates in wide temperature ranges from -40°C to 75°C with a rugged design built to withstand demanding environments.
  • Serial QoS Prioritization: Optimize network performance with configurable Quality of Service (QoS) for critical serial data.
  • High-Speed Redundancy: Ensure network uptime with Turbo Ring and Turbo Chain (< 20 ms recovery) and RSTP/STP support (IEEE 802.1w/D).
  • Advanced Network Management: Includes SNMPv1/v2c/v3, VLAN, IGMP snooping/GMRP, LACP, and RMON support for efficient monitoring and control.
  • Electromagnetic Protection: Features 15 KV ESD protection, 2 kV isolation (isolation models), and built-in surge protection for serial, Ethernet, and power interfaces.
  • Flexible RS-485 Configuration: Adjustable pull high/low resistor settings for customized signal tuning on RS-485 ports.
  • Wide Power Input: Supports 12 to 48 VDC input for versatile power installation options.

Ideal for Industrial Networking Applications

Whether you're modernizing legacy systems or deploying new industrial automation solutions, the S8455I delivers reliable connectivity for SCADA, factory automation, intelligent transportation systems, and remote monitoring. Its combination of serial device server functionality, managed switching, and fiber Ethernet flexibility makes it the perfect solution for complex industrial networks.
