Telemetry Terminal (RTU)
YRD-I4AL
Ultra-Low-Power Integrated RTU (pipeline network)
Product Overview
The YRD-I4AL integrates RTU, DTU, lithium battery and charge controller in one unit with built-in 4G/NB-IoT module. It embeds 500+ sensor protocols and dozens of center protocols, certified for hydrology and water resources. With <0.02 mA standby current, SOLAR charging input and IP68 protection, it is ideal for manholes and drainage networks without mains power.
