As a telemetry terminal with powerful functions and stable performance, Alotcer's mini low-cost telemetry terminal RTUAltRTU600M is widely used in hydrology, water resources, environmental protection, meteorology and other industries. Whether it is in irrigation area management, open channel flow monitoring, or water level observation at water intakes and groundwater, it can exert its powerful functions and provide accurate and reliable data support for various industries.

Application topology

Application advantages

Alotcer mini low-cost telemetry terminal RTU - AltRTU600M supports optional 5G, 4G, cat1, NB, redcap and other networks, and can be equipped with Beidou short message/ultra short wave/NB/lora/vibrating wire/esim/Bluetooth, etc. according to needs .

The equipment supports various water conservancy protocols/protocols, including "Hydrological Monitoring Data Communication Protocol" and "SLT 180-2015 Hydrological Automatic Measuring and Reporting System Equipment Telemetry Terminal", etc.

AltRTU600M supports preset conditions to trigger rainfall collection to ensure accurate monitoring; it is equipped with a network serial port camera to capture pictures. When an early warning is triggered, the device will immediately add data to help users respond quickly. Through remote testing, users can easily obtain real-time data and achieve efficient remote management.

The operating temperature is -35℃~75℃, the power interface has built-in reverse phase protection, overcurrent and overvoltage protection, wide voltage design DC 9~35V, 12V, standby current <1mA/sleep current about 25uA.

Wiring instructions

AltRTU600M has a 100% localization rate of materials and strong interface support capabilities, including RS232 (optional RS485), Ethernet, tipping bucket rain gauge, analog input, digital input (dry and wet contacts) and optional Control power output and other interfaces to meet the diverse needs of different application scenarios. At the same time, it also supports internal Flash to store data to ensure data integrity and security.
