The TP-11 converter is designed for reading data from devices with 4-20 mA interface with subsequent accumulation and transfer of this information to the LoRaWAN™ network. The battery for the converter is an irreplaceable battery, designed for a lifetime of up to 10 years. With battery power, the converter operates as Class A LoRaWAN™ device. The converter can operate from an external power source with a voltage of 10 ... 36 V. In that case, the converter operates as Class C device. In addition, the TP-11 converter has two security inputs that trigger the alarm message to the LoRaWAN™ network and two open-drain outputs for the external devices control.
