Industrial 4-Port 10/100M Ethernet Media Converter (Physical Isolation)

View : 609
Type : Physical Isolation Industrial Media Converter
Description :

This device is an Ethernet IEEE802.3 media converter designed to provide 4 physically isolated 100M Ethernet ports.


This device is an Ethernet IEEE802.3 media converter designed to provide 4 physically isolated 100M Ethernet ports. It offers a total fiber bandwidth of bidirectional 100 Mbps. The device supports transmission over various fiber distances, including 20/40/60/80/120 kilometers. It enables the transmission of 4 different types of Ethernet services while maintaining mutual isolation between them.


The device is specifically designed for harsh industrial environments.

It provides 1 100M fiber port and 4 100M Ethernet ports.

The total Ethernet bandwidth is 100 Mbps, transmitted through a single fiber. The 4 Ethernet signals received at the other end are completely independent, ensuring no interference or impact on each other.

The ethernet interface (RJ45) supports 10/100 Mbps auto-negotiation, full/half duplex mode, and MDI/MDI-X auto-detection.

The power supply features strong lightning protection, with resistance against high voltage induction and surge. The fanless design ensures efficient heat dissipation and reduces repair time.

● When powered by dual DC input (5.08mm terminal):

  It can be powered by a wide range of DC voltage from 9V to 70V or AC voltage from 7V to 50V. The power supply has automatic polarity detection, eliminating the need to distinguish positive and negative terminals during installation.

  ● It supports internal isolation, redundant dual power inputs, and reverse connection protection.

● When powered by AC input (3-prong AC socket):

  ● It supports AC voltage from 85V to 265V or DC voltage from 110V to 300V.

It has an IP40 protection rating, with an anodized aluminum alloy casing that can withstand harsh environmental conditions.

It provides DIN 35mm rail or wall-mount mounting options.

Wide temperature type: working temperature -40℃~ +85℃.

It has passed the 100% burn-in testing.

Warranty period: 5 years.
