The LNK-AINJ301M30series is a compact AI smart managed industrial PoEInjectorindependently developed by E-link.Itis a Hardened Gigabit High Power PoE Injector allows you to connect the IEEE 802.3 af/at PoE+device such as camera and access point with a nonPoE LAN switch within the distance of 100m.
This world-first innovative switch combines the dual advantages of managed and unmanaged switches.Engineers can monitor device status via multiple methods: mobile APP,PCweb management interface and LEDDisplaywithoutadditional test tools.
Datacover:voltage,current,temperature,Ethernet port status,PoEstatus,
We innovated this product based on standard switches:
Devicefunction:Scheduled System Reset, PoE ScheduledRestart. The redundant-mode supports auto -recover function. If the destination port of a packet is link-down, it forwards the packet to the other port of the backup pair
Meets IP40, aluminum housing, works stably under harsh industrial temperatures from -40℃to 75℃.
Equipped with dual redundant power supplies, it keeps Ethernet working stably 24X7.
Application Scenarios:
Intelligent Manufacturing & Automation:data transmission and multi-device interconnection
Power & New Energy: Surveillance communication andcluster networking.
Rail Transit & Tunnel Engineering: Real-time video monitoring andsignal transmission.
Oil, Gas & Mining Sites:Stablecommunication
Smart City & New Infrastructure Deployment
In addition, this product can be used in fields such as autonomous driving, humanoid robots, AI computing, metallurgy, chemical engineering, outdoor research base stations and field weather monitoring.
