Product Introduction
TD-DTU-PLUS is a device designed for data acquisition and remote transmission.It features a built-in high-capacity battery, eliminating the need for external power supply, and addresses the challenge of data acquisition and transmission in scenarios where power supply is unavailable on-site.Equipped with a 4G Cat-1 wireless communication module, it supports 2G+4G networks and GNSS positioning.The built-in wireless communication module adopts a modular design based on the Mini-PCIE standard interface, offering a variety of modules with different frequency bands to adapt to wireless networks in various countries and regions worldwide, enabling remote data acquisition and transmission.
Strong Compatibility
Supports multiple photoelectric ports and adapts to various communication interfaces of on-site meters.
Available Range
Supports multiple protocol configurations for plug-and-play use (no development required). It also enables the expansion of on-site applications, including remote control and environmental data collection.
Multi-Mode All Network Connectivity
As different countries use various communication cards, users can freely choose 2G/3G/4G and different data packets. Tespro's communication cards are suitable for global use.
Supported Protocols And Methods
Leave the protocol problem to us, so you can just go and use it with ease. What's more, it supports local storage: data is read first, saved first, and then uploaded once the network is available.
