Suited for industrial installations, retail, remote monitoring and other applications requiring reliable cellular connectivity.

## Long description

The DWM-311-TP 4G PoE modem provides reliable 4G LTE connectivity and Power over Ethernet (802.3af/at) in a compact industrial package. With dual-SIM failover, a Fast Ethernet PoE port and wide operating temperature range, the modem is designed for quick plug-and-play deployment in M2M and IoT applications such as environmental sensing, surveillance, traffic systems and small retail networks. The zinc-plated steel enclosure and DIN-rail mounting option support durable installation in demanding locations.
Advantages
The modem combines cellular data and PoE power delivery over a single Ethernet cable, reducing cabling and installation complexity. Dual-SIM failover and auto-reboot improve uptime, while PD-Alive and PoE scheduling help maintain continuous operation and optimize energy use. Industrial-grade housing and wide input voltage tolerance increase reliability in harsh environments.
Key specifications
Up to 150 Mbps 4G LTE data transfer speed
1 x 10/100 Fast Ethernet PoE LAN port (802.3af/at)
2 x SIM slots with failover capabilities
Plug-and-play operation — no complex setup required
Zinc-plated steel corrosion-resistant case
Operating temperature: -30 to 70°C

How to use
Install the DWM-311-TP on a DIN rail or other suitable surface, insert one or two SIM cards for carrier redundancy, and connect the modem to your PoE-enabled device using an Ethernet cable. Provide power via the PoE input (48–57 VDC) and configure network settings through the web-based interface if custom parameters are required. For most applications the device functions as plug-and-play and will automatically establish a 4G connection and supply PoE to the connected equipment.
Recommendations
For best performance, place the modem where it receives a strong cellular signal, ensure SIM cards are provisioned for data, and verify PoE power budgets for connected devices. Regularly check firmware updates and use DIN-rail mounting to secure the unit in industrial installations.
