In modern industrial operations, connecting multiple devices, sensors, and controllers securely and efficiently is crucial. Tespro Industrial Gateway with VPN provides robust, secure, and high-performance connectivity for IIoT systems, smart factories, and energy monitoring applications.
Equipped with dual SIM failover, VPN support, and compatibility with major industrial protocols, the gateway ensures reliable communication for PLCs, SCADA systems, sensors, and edge computing devices.

Tespro Industrial Gateway is built to withstand extreme industrial conditions:
· Operating temperature: -40°C to 75°C
· Vibration and shock resistance for factory floors and outdoor installations
· IP30/IP40 protection against dust and moisture
This rugged design guarantees continuous and reliable connectivity, even in remote or harsh industrial environments such as solar farms, oil and gas sites, and water treatment plants.

Reliable network connectivity is critical for industrial IoT systems. Tespro Industrial Gateway features dual SIM failover to maintain continuous connectivity:
Advantages:
· Automatic switch to backup SIM if the primary network fails
· Network uptime maximized for PLCs, sensors, and SCADA systems
· Failover response within 5 seconds ensures zero downtime
· This ensures industrial operations remain uninterrupted even when network conditions are unstable.

Tespro Industrial Gateway provides secure remote access with VPN
· OpenVPN, IPSec, and WireGuard protocols supported
· Encrypted communication for PLCs, SCADA, and IoT devices
· Secure remote troubleshooting and management
VPN ensures sensitive industrial data is protected while allowing engineers to monitor and maintain systems remotely.

The gateway supports essential industrial protocols:
· Modbus TCP/RTU for PLC communication
· MQTT for IoT messaging
· IEC 104 for SCADA integration
· OPC UA for secure industrial data exchange
This allows seamless integration of smart factory devices, energy monitoring systems, edge computing units, and sensors.

With cloud platform integration, operators can:
· Monitor gateway and device status remotely
· Upgrade firmware and manage system logs
· Receive real-time alerts and visualize industrial data
This improves operational efficiency, reduces field maintenance, and enables proactive industrial IoT management.
