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.

specifications for smart energy meters.
10. The external dimensions conform to: Q GDW 355-2013 single-phase
intelligent electric energy meter type specification.
11. The technical parameters comply with: Q GDW 364-2013 technical
specifications for single-phase smart energy meters.
12. Safety certification complies with: Q GDW 365-2013 Smart Energy

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.
