Rugged 4-Port Fast Ethernet + Video + RS485 + 1G Fiber Industrial Switch
Overview
The E-link LNK-GY4E1V1D Series is a physically isolated industrial Ethernet switch that
integrates 4x10/100M Ethernet, 1xVideo, 1xRS485, and 1xGigabit fiber uplink for secure and
efficient data transmission across multiple independent networks.
Built for demanding industrial applications, it enables simultaneous operation of private and public
networks without interference, ideal for video monitoring, automation, and DSLAM bandwidth
expansion.
Encased in an IP40-rated aluminum shell, it ensures high reliability, redundant power, and stable
operation from -40°C to +85°C in harsh field environments.
Features
4x10/100M isolated Ethernet ports with auto-negotiation and auto-MDI/MDI-X
Dedicated 1xBNC analog video input for real-time monitoring
1xRS485 data channel for control signal transmission
1xGigabit fiber uplink supporting multimode and single-mode up to 80km
Physical network isolation for enhanced data security and EMI protection
Redundant 24V DC dual power input with overload and polarity protection
IP40-rated aluminum enclosure, fanless and compact for industrial use
Wide operating temperature from -40°C to +85°C, supports DIN-Rail/wall mounting
Complies with EN50155, NEMA TS-2, and IEC industrial standards
