Tespro Launches Next-Generation Industrial Routers for Reliable Smart Infrastructure Connectivity

China, 3rd Jun 2026- IoT for industrial applications has a major issue with communication in some environments where connectivity is very unreliable. Most operators experience legacy systems that dont communicate, costly and time consuming implementations, and system downtimes. These headwinds complicate and delay operational decisions and increase operational costs.

With 20 years experience, Tespro has gained invaluable insights and is proud to unveil its innovative range of Industrial telecommunications devices with the TR-200 and TR-300 series of routers.
Technology Challenges
Communication issues are a reality for almost every field technician. Impediments to effective standard networking equipment are due to extreme distance, environmental conditions, temperature and voltage. Most available solutions operate with no redundancy, resulting in a total loss of data flow. This is compounded by the difficulties of integrating old modern cloud systems where legacy industrial devices use Modbus and other serial protocols. There is a need for connected devices that use 4G and 5G telecommunications without the burden of complex or costly development.

Another common problem is power instability. Industrial sites rarely have clean, stable power sources. Standard routers fail under voltage sags or surges. Finally, many devices do not fit on standard Industrial Gateway DIN Rail. This complicates installation in crowded electrical cabinets.
Tespros Solution
Tespro solves these problems with its new series of Industrial Router Modbus TCP-ready devices. These routers facilitate communication between serial sensors and cloud devices. The TR-224 and TR-324 have RS232/RS485 ports. These devices connect directly to legacy meters, PLCs, and RTUs and then convert and transmit data using Modbus TCP over cellular networks.

As an example, a water utility can connect an older flow meter using RS485 to a Tespro TR-225 router. The router communicates the flow data to a cloud-based analytics platform for real-time data. Water utility operators can monitor the flow data from the cloud, and there is no need to change the existing hardware. This allows the water utility to minimize time and save money.
Redundancy for Zero Downtime
Each Tespro Industrial Router 4G LTE has triple backup switching. This means the router will automatically change from a wired connection to WiFi to a 4G/5G connection. The dual SIM standbys will provide network diversity; if one of the networks is not working, the second network will the be functional one. The TR-244 and TR-245 models also have five 1000Mbps Ethernet ports that automatically adjust and adapt. These will allow critical systems to stay functional during the network outages.
Wide-Range Power & Temperature Tolerance
These routers can run from -40?C to 75?C, and can be used in the northern winters and the southern deserts. The dual-path wide-voltage power supply accepts DC 5-30V input. Current consumption is below 400mA, and these features have made the Industrial Gateway Solution for mobile equipment, factory floors, and outdoor cabinets.
4G/5G Gateway for Future-Ready Deployments
Tespro provides 4G/5G Gateway options. The TR-225 and TR-245 provide 5G LTE with 100Mbps, providing either 2 or 4 LAN ports. Meanwhile, The TR-325 and TR-345 provide 5G with gigabit LAN ports. The models provide exciting new capabilities to process video, large data logs, and control commands in real-time. These will be valuable assets for developing smart city systems and intelligent transportation networks.
Full Product Range
The TR-200 series includes:

o TR-224: 4G LTE, 2x 100Mbps LAN, RS485/RS232.

o TR-225: 5G LTE, 2x 100Mbps LAN, RS485/RS232.

o TR-244: 4G LTE, 4x 100Mbps LAN, RS485/RS232.

o TR-245: 5G LTE, 4x 100Mbps LAN, RS485/RS232.

The TR-300 series adds gigabit performance:

o TR-324: 4G LTE, 2x 1000Mbps LAN, dual RS485, RS232.

o TR-325: 5G LTE, 2x 1000Mbps LAN, dual RS485, RS232.

o TR-344: 4G LTE, 4x 1000Mbps LAN, dual RS485, RS232.

o TR-345: 5G LTE, 4x 1000Mbps LAN, dual RS485, RS232.

All models feature industrial-grade protection. They support public LTE networks and VPDN proprietary networks. The devices are universal, with standardized interfaces. They show resilience in trying circumstances.
Seamless AMI/AMR Integration for Utilities
Tespro routers work with AMI/AMR systems to safeguard and allow continuous communication of cloud and meter entities. They run on technology that saves energy and supports battery backup. The latency in data communication is eliminated. Utility companies will spend less on maintenance and will be able to respond to outages in a timelier manner.
