Product description
Lantronix SI-IES-521D-LRT – Dual-Port PoE++ Injector/Converter for Harsh Environments
The SI-IES-521D-LRT expands the capabilities of the SI-IES-5x1D-LRT series by offering two PoE++ ports, each supplying up to 90 watts. This makes it an ideal choice for deployments that require multiple high-power devices such as Wi-Fi 6/6E access points, PTZ cameras or multi-sensor surveillance units.
Multi-Gigabit Performance & Flexible Fiber Uplinks
Supporting up to 2.5G Ethernet and featuring a 1G/10G SFP+ slot, the device enables long-distance fiber backhaul and seamless integration into modern industrial, transportation and security networks.
Built for Demanding Industrial Conditions
With a robust IP31 metal enclosure and extended temperature tolerance from -40°C to +75°C, the SI-IES-521D-LRT is suitable for outdoor traffic cabinets, tunnels, parking facilities and industrial control cabinets.
Typical Applications
- Outdoor and indoor surveillance systems
- Smart transportation and traffic management
- Industrial automation and machine control
