Eliminate Remote Site Blind Spots
Eliminate Remote Site Blindspots Prevent remote PLCs and sensors from going down. Our cellular routers create always-on encrypted tunnels back to your central SCADA system, automatically failing over from wired WAN to 4G LTE the minute a primary network failure is detected.

Wired/4G Smart Failover
Internal logic constantly monitors WAN health. If the primary wired internet drops, the router automatically dials the 4G radio to maintain production data flow.
Enterprise-Grade VPN
Native support for IPsec and WireGuard. Establish highly encrypted, persistent tunnels from unmanned sites directly to your corporate firewall.
Port Forwarding & VLAN
Conserve limited IP resources. Use built-in NAT/Port Forwarding to map multiple downstream PLCs to a single cellular IP, while segmenting traffic via 802.1Q VLANs.

Wi-Fi Mesh & Roaming
Equipped with 802.11 b/g/n Wi-Fi. Supports 802.11r fast transition and Mesh configurations to expand wireless coverage across expansive factory floors.
Global Frequency Bands
Unlocked Micro SIM slot. Compatible with major carrier networks across EMEA and Asia (LTE-FDD B1/B3/B5/B7/B8/B20) for seamless global deployment.
Smart Backup & -40~85°C
Engineered for continuous operation with automatic link recovery. Rated for extreme -40°C to +85°C ambient cabinet temperatures.
Applications Of Industrial Cellular Routers
Engineered to secure remote unmanned assets where wired broadband is unavailable.

Water & Wastewater Pump Stations
Providing secure VPN backhaul for remote PLC telemetry data from isolated municipal water facilities.

Renewable Energy Smart Grids
Executing continuous Modbus RTU-to-TCP polling for solar inverter arrays across vast, hot desert deployments.

Secure ATM & Vending Networks
Replacing expensive leased lines with highly encrypted, low-latency 4G connections for secure financial transactions.

Elevator Remote Diagnostics
Mounting natively on DIN-rails inside cramped elevator shafts to transmit real-time predictive maintenance alerts.

Smart Bus Fleet Management
Utilizing anti-vibration armor and built-in Wi-Fi to deliver passenger internet and transmit onboard CCTV feeds.

Smart Agriculture IoT
Aggregating soil sensor data and orchestrating automated irrigation systems reliably from deep rural locations.
What Our Clients Say
Real-world reliability verified by field systems integrators.
“We deploy these routers in remote solar farms where temperatures regularly hit 65°C inside the cabinet. The smart backup logic is brilliant—if the cellular tower drops the connection, the VT-LTE400 restores the VPN tunnel automatically without us having to drive 3 hours to cycle the power.”
“We have our main factory broadband on WAN port and a 4G SIM in as backup. Last month a backhoe cut our fiber line. The Valtoris router switched to LTE so fast that our main SCADA polling loop didn’t even see an alarm. Phenomenal engineering.”

Frequently Asked Questions
How fast does the router failover from the wired WAN port to the 4G LTE backup?
Our 4G/Wired Smart Backup function relies on continuous hardware and ping-level link monitoring. When a physical drop or severe packet loss is detected on the primary WAN port, the internal routing table instantly shifts traffic to the active cellular interface. In most SCADA environments, this failover executes within seconds, ensuring your polling software does not experience a prolonged timeout.
Will maintaining an IPsec VPN tunnel consume my entire monthly M2M cellular data plan?
No. We understand that industrial M2M SIM cards often have strict 50MB to 500MB monthly limits. The VT-LTE400’s IPsec implementation utilizes optimized Dead Peer Detection (DPD) and Auto-Reconnect parameters. Tunnel maintenance requires only a few kilobytes per day when idle (no actual PLC data is transmitted), which is perfect for metered remote telemetry applications.
What happens to the router configuration during a remote brownout or power loss?
All network configurations, firewall rules, and VPN certificates are saved to non-volatile flash memory. During a sudden power loss, no settings are lost. The moment DC 9~24V power is restored, the operating system boots, the cellular module re-registers with the cell tower, and the VPN tunnels are automatically re-established without any human intervention.
Can I completely disable the Wi-Fi broadcast to comply with strict IT security policies?
Yes. Many energy and utility sites prohibit wireless broadcasting. You can log into the local Web UI (default 192.168.8.1) and completely disable the 802.11 b/g/n radio interface. The VT-LTE400 will then operate purely as a hardened, closed-loop Wired-to-Cellular gateway, routing traffic exclusively through the physical RJ45 LAN ports.
