Product Overview

The ISF401 is a 100 Mbps industrial-grade fiber media converter, functioning as a non-managed industrial Ethernet switch. It provides conversion between 4 x 10/100Base-TX twisted pair electrical signals and 1 x 100Base-X SC optical signal, utilizing advanced switching technology and store-and-forward methods for efficient data transmission.

Built to industrial standards, the ISF401 features dual redundant power supply support and is designed to be dustproof, moisture-proof, and resistant to lightning and extreme temperatures. With a robust Mean Time Between Failures (MTBF) of 300,000 hours, this switch is ideal for various industrial applications, including industrial automation control, traffic control systems, building automation, and data center monitoring. It ensures reliable performance for the Industrial Internet of Things (IIoT), making it suitable for long-term operation in harsh environments.

Key Features

  • 4 x 10/100Base-TX Ethernet ports and 1 x 100Base-X fiber optic port
  • Supports 10/100 Mbps speed auto-negotiation on all Ethernet ports
  • Automatic half/full duplex negotiation and Auto MDI/MDI-X functionality on all ports
  • Supports wire-speed forwarding for smoother and more efficient data transmission
  • Equipped with imported lightning protection components to withstand lightning strikes and high voltage surges
  • Designed for a wide temperature range from -45°C to +85°C, ensuring adaptability to extreme conditions
  • Dual redundant power supply support with overload and reverse polarity protection
  • Plug-and-play design for easy installation without any configuration required
  • IP40-rated protection with a rugged, high-strength metal housing; fanless design with low power consumption
  • IEC Class A electromagnetic protection, providing superior electromagnetic compatibility (EMC)
