Router industrial 4G LTE Cat 4 Milesight UR32L-L04EU-P com PoE, Dual SIM, série, I/O, VPN, caixa metálica, calha DIN

Where basic office routers stop at Wi-Fi coverage, the Milesight UR32L-L04EU-P starts its work: built for the machine room, the remote cabinet, and the outdoor enclosure. This industrial cellular router pairs 4G LTE Cat 4 connectivity with 802.3af/at Power over Ethernet, so a single cable can carry both data and power to the device. Dual Mini SIM slots with automatic failover keep the uplink alive when one carrier drops, while the wide 9–48 V DC input and -40 °C to +70 °C operating range mean it fits into harsh environments without extra cooling or heating.

Highlights

• 4G LTE Cat 4 with fallback to 3G and 2G; up to 150 Mbps down / 50 Mbps up
• Two 10/100 Mbps Ethernet ports, one configurable as WAN or LAN
• 802.3af/at PoE PD — power the router directly from a PoE switch or injector
• Dual Mini SIM (2FF) slots for carrier redundancy and failover
• RS232/RS485 serial port plus digital input and digital output for industrial integration
• Comprehensive VPN support: OpenVPN, IPsec, PPTP, L2TP, GRE, DMVPN
• Metal housing, IP30 protection, DIN-rail and wall-mount options

In daily use

Deploy the UR32L-L04EU-P as the primary gateway for remote metering, vending, digital signage, or SCADA applications. The configurable serial port bridges legacy Modbus RTU/ASCII devices to Modbus TCP or MQTT, while the digital I/O can trigger alarms or accept external sensors. Management is straightforward via Web GUI, CLI, SNMP, or Milesight DeviceHub for centralised fleet control. The router supports advanced routing protocols such as OSPF and BGP, and VRRP for high-availability setups. With PoE PD, you can install the unit in locations without a nearby power outlet, reducing cabling cost and complexity.
