DDZY2397 single-phase IoT Bluetooth parent-child electric energy meter consists of one parent meter and multiple child meters. It adopts digital signal processing chip, permanent storage of information, standard LoRaWAN,Cat. 1, Bluetooth and RS485 communication interface, LCD and other technologies. The advanced SMT surface mounting process is adopted for the electric energy meter. The shell is made of high-strength, flame retardant and environment-friendly materials, which is novel, beautiful and applicable. It has high insulation strength and corrosion resistance. The meter integrates many functions, including electric energy metering, information storage and processing, information interaction, etc.
Example: the platform issues instructions that are sent to the corresponding parent meter through the communication interface of LoRaWAN/NB-IoT/Cat.1/WiFi (optional). The parent meter then transmits the instructions to the child meters via Bluetooth. Upon receiving the data, the child meters within multiple ranges will perform corresponding operations based on the child meter information in the data. When the child meters upload data through Bluetooth, the data also contains the entered parent meter information, and the corresponding parent meter sends back the data to the platform after receiving it.
1.Communication modes: Built-in Bluetooth/LoRaWAN/NB-IoT/Cat.1/WiFi communication modules and SIM cards, suitable for 4G/5G operator networks.
2.Electric energy metering: the function of measuring positive active and negative active electric energy. It can measure, store and display the voltage, current, power, power factor, frequency and other operating parameters and status of the current watt hour meter.
3.Remote on-off: send power off command through Bluetooth/LoRaWAN/NB-IoT/Cat.1/WiFi communication modes to cut off the user's load circuit. Or send the power transmission command to connect the user load circuit.
4.Data communication: active upload/two-way transparent transmission function. Actively transmit data to the corresponding platform through Bluetooth/LoRaWAN/NB-IoT/Cat.1/WiFi (optional) wireless network. The default interval is 4 hours (settable).
5.Power Limitation: optional maximum power limitation and intelligent anti-theft electricity. It has overload protection function.

INSTALLTION
Live installation of wiring is strictly prohibited!
The electricity meter shall be installed indoors as far as possible. Special instrument box protection shall be used for outdoor installation. The installation bottom plate shall be fixed on the wall with strong fire resistance and not easy to vibration. There must be no corrosive gases in the surrounding air where the meter is installed. Avoid dust, salt spray, etc.
When using the electricity meter, the wiring must be conducted strictly according to the wiring diagram in the tail cover of the meter. It is recommended to use copper wire for the lead connected to the terminal seat. The screws of the fixed lead in the terminal seat should be tightened to avoid burning the electricity meter due to bad contact and heating.
TRANSPORTATION AND STORAGE
Ammeters must be transported and stored under the original packaging conditions. Products shall not be severely impacted during transportation and unpacking, and shall be transported and stored according to GB / T 25480-2010 Basic Environmental Conditions for Instrument Transportation and Storage and Test Methods as stipulated in 2010. The products should be stored in the warehouse and placed on the platform frame. The stacking height shall not exceed five layers. No corrosive gases shall be present in the stored environment.
