Tespro DTU is designed to deliver fast, reliable, and secure data transmission for industrial IoT and automation applications, where real-time data from sensors, PLCs, and SCADA systems is increasingly critical. With dual SIM redundancy, VPN security, and support for multiple industrial protocols, this DTU ensures uninterrupted data flow between field devices and cloud or SCADA platforms.
Built for the most challenging industrial environments, the Tespro DTU operates at temperatures from -40°C to 75°C, resists shock and vibration for factory floors and outdoor installations, and offers IP30/IP40 protection against dust and moisture. This robust design guarantees stable data transmission in harsh conditions, including energy plants, water treatment facilities, and remote IIoT sites.
Reliable data transmission is essential for industrial IoT, and the Tespro DTU features dual SIM redundancy that automatically switches to a backup SIM if the primary network fails. This delivers continuous connectivity for PLCs, sensors, and SCADA systems, with automatic failover within five seconds, ensuring uninterrupted industrial operations and real-time monitoring. As a result, critical industrial applications experience zero downtime.
For data security, the DTU includes built‑in VPN support for OpenVPN, IPSec, and WireGuard, encrypting industrial data for SCADA and PLC communications. This enables secure remote management and troubleshooting, keeping sensitive industrial data protected while allowing remote engineers to monitor and manage systems globally.
The DTU also supports widely used industrial protocols: Modbus TCP/RTU for PLC communication, MQTT for IoT messaging, IEC 104 for SCADA integration, and OPC UA for secure industrial data exchange. This broad compatibility makes it suitable for smart factories, energy monitoring, water treatment, and remote IIoT applications, seamlessly connecting multiple devices.
With cloud management integration, operators can monitor device status and network health remotely, upgrade firmware and manage logs, and receive real‑time alerts while visualizing industrial data. Cloud integration enhances operational efficiency, reduces field maintenance costs, and supports proactive industrial IoT management. Key applications include energy plants (real‑time telemetry and remote monitoring for solar, wind, and hydro stations), water and wastewater facilities (pump, valve, and sensor data collection), smart factories (connecting PLCs, sensors, and monitoring devices to cloud platforms), and remote industrial IoT (reliable data transfer for edge devices and AI monitoring systems).
Tespro DTU maintains connectivity even in remote industrial sites with unstable networks, thanks to its dual SIM redundancy. It supports secure remote data transmission via OpenVPN, IPSec, and WireGuard, and is compatible with Modbus TCP/RTU, MQTT, IEC 104, and OPC UA, enabling seamless integration with PLCs, sensors, and IIoT devices. In conclusion, the Tespro l DTU provides real‑time, secure, and reliable data transmission for industrial IoT applications. Its industrial‑grade design, dual SIM redundancy, VPN security, and multi‑protocol support make it an ideal solution for smart factories, energy plants, water treatment facilities, and remote IIoT networks. Investing in the Tespro DTU ensures continuous, secure, and efficient industrial data communication, supporting modern IIoT and automation operations.
