Remote Terminal Unit

1、Remote Terminal Unit Product Overview

Remote Terminal Unit provides comprehensive functions such as collection, storage, transmission, display, control, alarm and transmission of hydrological and meteorological data.A Remote Telemetry Unit (RTU), also known as a remote terminal unit, is a microprocessor-controlled electronic device primarily used for remote data monitoring and transmission in fields such as meteorology, hydrology, and geology. It connects to a central monitoring station via a distributed control system or SCADA system, and possesses data acquisition, transmission, storage, and remote control capabilities.

Based on application scenarios, it is categorized into types such as hydrological and water resource type, groundwater type, weather station, and geological monitoring station. It can integrate functions such as water level/rainfall monitoring, meteorological monitoring, and pest/soil moisture monitoring, and is suitable for unattended scenarios such as flash flood warning and reservoir monitoring.

3、Remote Terminal Unit Device Functionality Support

This device features a low-power design, is compatible with solar power supply scenarios, and supports multiple communication methods including RS232/485, GPRS, Bluetooth, 4G, and BeiDou.

It supports IPv4, IPv6, and domain name connections, allowing for simultaneous multi-IP connections for multi-site data transmission.

The hardware integrates an analog signal input module (4-20mA), a switch signal input module, a relay control interface, and multi-sensor connectivity. It features an industrial-grade protection design and wide operating temperature range (-40℃ to +85℃).

*Built-in temperature and humidity module for real-time monitoring of internal temperature and humidity changes.

Multiple protection circuits prevent short-circuit damage to the device in case of abnormal external forces.
