📝 Product Description
The M21F-V50 Telemetry Terminal integrates the functions of a traditional hydrological telemetry terminal, wireless long-distance transmission via 2G/3G/4G full-network compatibility and NB-IoT short message, and wireless short-distance transmission via LoRa. It delivers comprehensive capabilities including data collection, storage, transmission, display, control, alarm for hydrology, water resources, geological disaster monitoring, meteorology, and other fields.
Equipped with a high-performance industrial-grade 32-bit communication processor and industrial-grade wireless modules, the terminal is supported by an embedded real-time operating system. It provides a complete set of interfaces including a tipping bucket rain gauge interface, RS232, RS485, SDI, wired Ethernet port, 4~20mA and 0~5V analog input, digital input, relay output, and digital output.
