Powering Legacy Edge Devices | E-link China Industrial 5VDC Output PoE+ Splitter

One Cable, Two Solutions: Industrial PoE+ Splitter Delivers Gigabit Data and 5VDC Power, Redefining Edge Device Power Architecture

802.3af/at Input, Regulated 5VDC/2A Output, -40~80°C Operation. Provides Zero-Modification Access for Traditional Non-PoE Devices.

In Industrial IoT deployments, a vast number of legacy devices (such as serial servers, specific sensors, display units, etc.) still rely on traditional DC power supplies like 5V, 12V, or 24V. They cannot directly utilize the increasingly prevalent PoE networks for power, forcing the deployment of separate power cabling on-site, which adds complexity and cost. To solve this "last-meter" challenge of integrating power and data, E-link China officially introduces the Industrial Gigabit PoE+ Splitter. This product intelligently separates a standard PoE network signal into a gigabit data stream and a stable 5VDC power output. It enables seamless integration of existing non-PoE devices into modern, unified industrial Ethernet architectures without any modification, serving as a critical bridge for the network upgrade of traditional equipment.

Core Functionality: Decoupling and Enabling

1. Intelligent Separation, Clean Outputs:

   • Single Input Port (RJ-45 PoE IN): Receives the combined data and power signal from a standard 802.3af/at PoE switch or injector.

   • Dual Independent Outputs:

     • Data Output Port (RJ-45 DATA OUT): Provides a pure Gigabit Ethernet data signal, ensuring lossless 10/100/1000BASE-T transmission.

     • Power Output Terminal (2-pin Terminal Block): Delivers a stable, isolated 5VDC supply, with a maximum output current of 2A (10W), meeting the needs of most low-power, non-standard devices.

2. Industrial-Grade Reliability Design:

   • Comprehensive Protection: Built-in output short-circuit, overload, and reverse-connection protection safeguards both the upstream PoE equipment and the downstream powered device.

   • Wide Environmental Tolerance: Operates in a -40°C to 80°C temperature range. Features an IP40-rated, fanless metal housing and supports DIN-rail and wall-mount installation for harsh industrial environments.

   • Remote Diagnostic Visibility: Equipped with comprehensive LED status indicators (PoE Status, Data Link, Power Output) for quick troubleshooting.

Typical Application Scenarios

• Industrial Camera Retrofit: Provides a PoE power solution for older or specific industrial cameras that only support 5V DC power, eliminating the need to replace the camera or run new power lines.

• Serial Device Networking: Supplies both data and power to RS-232/485 to Ethernet converters, PLC programmers, etc., simplifying wiring inside control cabinets.

• IoT Gateway/Sensors: Powers wireless gateways, LoRa concentrators, or various sensors that use 5V power, enabling single-cable deployment for remote wireless nodes.

• Digital Signage & Displays: Powers small indoor/outdoor information displays, utilizing existing network cabling for deployment.

• Security Auxiliary Equipment: Powers access control panels, alarm hosts, and other security subsystem devices.

Customer Value: Simplification, Cost Reduction, Efficiency Gain

• Lower Deployment Cost (TCO): Eliminates the cost of running separate AC-DC power lines and installing outlets for individual devices, saving up to 60% in cabling materials and labor.

• Increase System Reliability: Centralized PoE power is easier to manage and maintain, and can be backed by UPS to keep critical devices online during mains power failure.

• Enhance Deployment Flexibility: Device placement is no longer constrained by power outlet locations, allowing optimal placement (e.g., ceilings, pillars, remote points).

• Protect Existing Investment: No need to scrap or extensively modify existing non-PoE equipment, extending its service life and enabling a smooth transition to a fully networked architecture.
