Overview of M single-phase cost-controlled intelligent electric energy meter (module-remote-switch internal and external)
DDZY88-M single-phase cost-controlled intelligent electric energy meter (module-remote-switch internal/external), adopts advanced solid-state integrated circuit technology and SMT technology, is suitable for measuring AC single-phase active energy with a frequency of 50Hz, and its performance is in line with GB /T 17215.321-2008 technical requirements. This product has a two-way metering function, which can accurately measure the active energy in the positive and negative directions, and can set the combined active energy according to this, with the time-sharing measurement function; the active energy is divided into peaks, peaks, flats, valleys, etc. Time period electric energy and total electric energy are respectively accumulated and stored. It has LCD display function (with button wake-up LCD display function when power failure), RS485, power line carrier (or wireless) and infrared communication function, and the realization method of cost control function is remote mode.

The main function
1. Support 4 rates, 14 time zones throughout the year, 14 time periods can be set every day, two sets of rate timetable switching, and special timetable settings for holidays.
2. Supports the function of tiered electricity, does not support tiered electricity price, and requires background settlement.
3. Support the reset function under the condition of the key and programming permission, the bottom value of the electric energy meter can only be reset to zero, and setting is prohibited.
4. Support data storage function, which can store two-way total electric energy and electric energy data of various tariffs for the last 12 settlement days.
5. Support freezing function, with time freezing, instantaneous freezing, daily freezing, agreed freezing, and whole point freezing.
6. Support event recording function, can record the total number of power failures, the total number of programming, the total number of time calibration, the total number of open meter cover, pull and close events; can permanently record the time of the electric meter reset event and the time of reset The electrical energy data.
7. Support cost control function, which can be realized remotely through virtual media such as RS485 and remote power sales system, and through virtual media to set power parameters in the electric energy meter, pull and close commands, and alarm instructions, by the electric energy meter An alarm signal is issued to remind users to pay for electricity.
8. Support alarm function, with light alarm output. The light alarm uses a red constant light indicator, and the alarm automatically ends when the event returns to normal.
9. Support functions such as security authentication. When setting parameters and issuing remote control commands for the electric energy meter through virtual media, strict ESAM module security authentication is required to ensure safe and reliable data transmission.
10. Support the current domestic commonly used narrowband spread spectrum power line carrier schemes such as 76.8kHz, 120kHz, 132kHz, 270kHz, 390kHz, 421kHz, and 470~510M wireless communication frequency points.
11. The load switch is divided into two ways: built-in and external.
