开关量输出为继电器输出，可实现“遥控”和报警输出。
开关量输入是采用开关信号输入方式，由外部电源供电。当外部接通或断开时，经过仪
表开关输入模块采集其接通或断开信息并通过仪表本地显示。开关量输入不仅能够采集和显
示本地的开关信息，同时可以通过仪表的 RS485 实现远程传输功能，即“遥信”功能。
Switching output is relay output, can achieve the remote-control and alarm output.
The switch input adapts the method of on-off signal input and powered by outer power supply.
It can be gotten by meter when there is a change of on or off via a switching input module. The
parameter of switching input can not only get and show the state of local switching information
but also achieve the communication via RS485, which called “remote information”function.

7 主要功能特点 Function description
7.1 测量功能 Measurement
能测量全电力参数包括电压 U、电流 I、有功功率 P、无功功率 Q、视在功率 S、功率
因数 PF、频率、31 次分次谐波及总谐波含量。其中电压 U保留 1位小数，频率 F保留 2位
小数，电流 I保留 2位小数，功率 P保留 3位小数。
如：U = 220.1V，f = 49.98Hz, I = 1.99A，P = 0.439kW

7
The meter can measure all electrical parameters such as voltage, current, active power,
reactive power, apparent power, power factor, frequency, 31st harmonic and total harmonic. The
value format of voltage, current, frequency and power are listed as below.

7.3 分时功能 Timing
两套时段表，一年可以分为 4个时区，每套时段表可设 8个日时段，4个费率(F1、F2、
F3、F4 即尖峰平谷) 。分时计费的基本思想就是把电能作为一种商品，利用经济杠杆，用
电高峰期电价高，低谷时电价低，以便削峰填谷，改善用电质量，提高综合经济效益。
The meter has 2 time lists, and can be divided into 4 time zones per year. Each time list can
be divided into 8 time periods and 4 tariff (F1、F2、F3、F4). The main purpose of multi-tariff is
promote the energy efficiency and economic benefits.
7.4 需量功能 Demand
有关需量的相关概念如下：
There are some definitions on demand:
需量
Demand
需量周期内测得的平均功率叫需量
The average power in the demand cycle.
最大需量
Maximum demand
在指定的时间区内需量的最大值叫最大需量
The maximum value of demand in a period of time.
滑差时间
Slip time
从任意时刻起，按小于需量周期的时间递推测量需量的方法，所
测得的需量叫滑差式需量。递推时间叫滑差时间
需量周期
Demand cycle
连续测量平均功率相等的时间间隔, 也叫窗口时间
The time period between two same average value of demand.
缺省需量周期为 15 分钟，滑差时间为 1分钟。
能测量 4种最大需量即正向有功、反向有功、感性无功、容性无功最大需量以及最大
需量发生的时间。
The default demand cycle is 15 minutes, slip time is 1 minute.
The meter can measure 4 kinds of maximum demand: forward active, reversing active,
inductance performance reactive, capacitance performance reactive maximum demand and the
occur time.
7.5 历史数据统计功能 History data statistics
能统计上 48 月的历史电能（各费率电能）和上 90 日的历史电能（各费率电能）。
The meter can record last 48 months or last 90 days history energy in each tariff.
7.6 开关量输入输出功能 Switching input and output
有一路开关量输出，一路开关量输入，开关量输出为继电器输出，可以实现“遥控”和

8
报警输出。开关量输入不仅能够采集和显示本地的开关信息，同时可以通过仪表的 RS485
实现远程传输功能，即“遥信”功能。
The switch input adapts the method of on-off signal input and powered by outer power supply.
It can be gotten by meter when there is a change of on or off via a switching input module. The
parameter of switching input can not only get and show the state of local switching information
but also achieve the communication via RS485, which called “remote information”function.

9 通信说明 Communication description
仪表 RS485 通信接口支持 MODBUS-RTU 通信协议，通信口波特率可在 1200bps、2400
bps、4800 bps、9600bps 和19200 bps 之间设置，校验位为无校验。
仪表的 RS485 通信口要求使用屏蔽双绞线连接，布线时要考虑整个网络的布局：如通
信线缆的长度、走向、上位机的位置、网络末端的匹配电阻、通信转换器、网络可扩展性、
网络覆盖范围、环境的电磁干扰情况等因素，都要综合考虑。
The meter adapts MODBUS-RTU protocol, and the baud rate can be chosen from 1200bps、
2400 bps、4800 bps、9600bps and 19200 bps. The parity is None.

13
The meter needs shielded twisted pair conductors to connect. Customers should consider the
whole network’s parameters such like communication wire’s length, the direction, communication
transformer and network cover range, etc.
注：
在布线工程上要严格按要求施工；
对于暂时不需要通信的仪表都要将他们连接到 RS-485 网络上，以便于诊断和测试；
进行 RS-485 电缆连接时，尽量使用双色双绞线，所有的 485 通信口“A”端接同一种颜色，
“B”端接另一种颜色。
RS-485 总线(从上位机通信口开始到任一被连接的仪表终端通信口)长不超过 1200 米。
Note:
Wiring should follow the wiring requirements;
Connect all the meter in the RS485 net work even some do not need to communication, which is
benefit for error checking and testing;
Use two color wires in connecting wires and all the A port use the same color.
No longer than 1200 meters of RS485 bus line.
9.1 地址表 Address table
仪表支持 MODBUS-RTU 协议中的 03H 命令与 10H 命令，03H 为读多个寄存器，10H
