Supports 4G full network connectivity, seamlessly compatible with all 4G network standards of the three major operators, including TD-LTE, FDD-LTE, etc. Adopting industrial grade design, wide voltage power supply, built-in watchdog function, working temperature range of -25 ° C~75 ° C.

The RS485 hub can realize the expansion of 1-way RS485/RS232 to 4-way RS485, and connect multiple RS485 devices (such as sensors, controllers, displays, etc.) to the same bus system through the hub. It can expand the scope of the communication system, support more equipment interconnection, reduce signal interference and signal attenuation, improve communication stability and transmission efficiency. This series of products are designed according to industrial standards, with power isolation, signal isolation, lightning protection and anti-static design, stable and reliable.

Modbus RTU / TCP converter is a key device in industrial communication. It realizes two-way conversion of two Modbus protocols through serial port and Ethernet interface, supports parameter configuration and data mapping, solves protocol compatibility problems, and improves system integration flexibility.

The RT-T electric meter series is a remote acquisition terminal for electrical parameters that supports multiple communication modes. The open current transformer sampling method is adopted to support the sampling of voltage, current, electric energy and power.
