Hardware & Enclosure Features
Compact DIN-Rail Mount: This standard 35mm design lets you install it in crowded control panels without taking up too much space.
Rugged Industrial Build: This outdoor-ready case is built to last in extreme temperatures and with a lot of electrical noise.
Versatile Interfaces: Equipped with 1×WAN, 4×LAN, WiFi, and 4G LTE ports that make it easy to connect to older PLCs and embedded systems.
High-Speed Processing: Advanced 32-bit industrial processor makes sure that complex network protocols and large data volumes are handled quickly.
Networking & Security
Smart 4G/Wired Failover: Automatically switches between the main wired WAN and a backup cellular network to make sure there is no downtime.
Flexible Routing Modes: Works with WAN to LAN/WiFi, WiFi to LAN/WiFi, and 4G to LAN/WiFi setups for different types of networks.
Enterprise-Grade Security: Built-in stateful firewall and secure VPN protocols protect critical industrial operations from unauthorized access.
A: Yes, metal control cabinets make wireless signals much worse by creating a Faraday cage effect. The VT-LTE400 has a standard 50Ω/SMA antenna interface. If you’re putting the router inside a metal box, we strongly suggest that you skip the standard glue stick antenna and use the optional suction cup antenna instead. This lets you move the antenna to the outside of the cabinet for the best 4G and WiFi reception.
A: The VT-LTE400 is meticulously developed for highly reliable, low-bandwidth industrial IoT telemetry , such as transmitting Modbus TCP and MQTT data. Its maximum LTE transmission rates of 10Mbps down and 5Mbps up are perfectly suited for PLC data acquisition and SCADA system polling. However, continuous multi-channel HD video streaming may exceed this capacity.
A: The VT-LTE400 provides connectivity through its integrated 4×10/100M LAN ports. To integrate older PLCs that lack Ethernet interfaces, you will need to deploy one of our [Serial Port to Ethernet Converters] alongside the router. The converter will translate your legacy serial protocols (like Modbus RTU) into Modbus TCP, allowing the VT-LTE400 to seamlessly bridge that data into centralized enterprise networks via encrypted VPN.
A: The router is engineered with a smart wired-to-4G failover that automatically switches to the 4G network if the WAN port fails , ensuring reliable connectivity in critical operations. While this hardware-level failover happens in milliseconds, a brief transition period occurs. To achieve zero data loss, ensure that your edge gateway software or MQTT clients are configured with local data buffering and automatic reconnect features to perfectly complement the router’s hardware redundancy.
