注：1.负极电流分流器输入时，需在仪表菜单将
选项设置为on，详见第6节菜单编程界面。
2.当两路电流输入均采用霍尔电流传感器输入
时，第二路霍尔电流传感器的电源不能使用电
表内置电源，需外配电源模块。
3.电流采用分流器输入，四线制接法所测量的电
压值会有额外千分之一左右的误差。
4.电流信号线推荐使用0.75mm2或1mm2屏蔽双
绞
线，且屏蔽层需要接大地。
Note: 1. When current shunt is connected to the
negative, set the option to on in the
meter menu, see section 6 menu programming
interface for details.
2. When the two current inputs are input by the
Hall current sensor, the power supply of the
second Hall current sensor cannot be used
with the built-in power supply of the meter,
and the power module needs to be externally
connected.
3. When the current is input by the shunt, the
voltage value measured by the four-wire
method has an error of about one thousandth.
4. It is recommended to use a 0.75mm2 or
1mm2 shielded twisted pair for the current
signal line, and the shield layer needs to be
connected to the ground.

4.3 注意事项Precautions
4.3.1 电压信号输入Voltage input
输入电压不得高于产品的额定输入电压的
120%，在电压输入端须安装 1A 保险丝。
The input voltage must not exceed 120% of the
rated input voltage of the product. A 1A fuse must be
installed on the voltage input.
4.3.2 电流信号输入Current input
电流输入应使用外部分流器或霍尔电流传感
器。
An external shunt or Hall current sensor should
be used for current input.
4.3.3 通讯接口接线Communication interface wiring
该仪表提供异步半双工 RS485 通讯接口，采用
MODBUS-RTU 协议，各种数据信息均可在通讯线路上
传送。理论上在一条线路上可以同时连接多达 128
个仪表，每个仪表均可设定其通讯地址（Addr）、
通讯速率（baud）也可通过设置选择。
The meter provides asynchronous half-duplex
RS485 communication interface using
MODBUS-RTU protocol, a variety of data
information can be transmitted on the communication
line.Theoretically, up to 128 meters can be connected
simultaneously on a single line. Each meter can be set
with its address (Addr), baud rate, or setting selection.
通讯连接建议使用三芯屏蔽线，每芯截面不小
于 0.5mm2，分别接 A、B，屏蔽层接大地，布线时应
使通讯线远离强电电缆或其他强电场环境。
The communication connection is recommended
to use three-core shielded cable, Cross-sectional area
of each core is not less than 0.5mm2, is connected to
A、B respectively, shielding layer is connected to the
earth. The wiring should be kept away from strong
cables or other strong electric field environment.
建议起始端和最末端仪表的 A、B 之间均加匹
配电阻，阻值范围为 20Ω～10kΩ。
It is recommended to add matching resistors
between A and B of the meters at the beginning and
end. The resistance range is 20Ω to 10kΩ.

6.1 开关量输出设置 Switch output setting
仪表开关量输出采用继电器输出，有两种控制
方式：1、报警方式（“SEL”选择不为零）；2、总线
控制方式（“SEL”选择为“0. do”,此时“dLy”设
置为 0为电平输出方式，设置非零为脉冲方式动作
后延时设置的时间自动断开）
“SEL”中设置 DO 输出类型，“0. do”表示为
通信控制（此时如果 DLY 设置为 0输出为电平方式，
否则为脉冲方式，如果 DLY 设置为 2，吸合后 0.02
秒自动断开），其他为报警控制（见下表）
“dLy”为报警延时（报警用时推荐不设置为
0防止干扰误动。）
“bAnd”为不动作带设置
The switch output of the meter adopts relay
output. There are two control modes: 1. Alarm mode
("SEL" selection is not zero); 2. Bus control mode
("SEL" is selected as "0. do". When “dLy” is set to 0,
it is the level output mode. Setting non-zero as the
pulse mode will automatically disconnect the delay
setting time.
“SEL” sets the DO output type. “0. do” means
communication control. (If DLY is set to 0, the output
is in level mode , otherwise it is in pulse mode. If
DLY is set to 2, automatic shutdown will take 0.02
seconds after pull in. Open), same as alarm control
(see the following table)
"dLy" is the alarm delay time (it is not
recommended to set to 0 during the alarm to prevent
interference error.)
"BAnd" is set for the non action band

第一路继电器输出
First relay output
由通信控制的 DO 输出模式，此时“dLy”为 0则为电平控制。设置其他
值为自动返回模式。DO 动作后延时“dLy”（单位为 0.01 秒）后自动断开
The DO output mode controlled by the communication, when "dLy" is 0, it is
the level control. Set the other value to auto return mode. DO disconnect

时设置范围 1－9999 时，单位：1秒；
Output delay time: If it is DO output mode, when it is set to 0, it is the level control mode; when it is
not 0, it is the pulse control mode, and is disconnected after the setted delay time, the delay setting
range is 1-255, unit: 0.01 seconds; if it is alarm output mode, delay setting range is 1-9999, unit: 1

7.1 概述 Overview
DJSF1352-RN 仪 表 采 用 Modbus-RTU 协议：
“9600，8，n，1”，其中 38400 为默认波特率，可
通过编程修改为 1200、2400、4800、9600 等，；8
表示有 8个数据位；n表示无奇偶校验位；1表示
有1个停止位。
The DJSF1352-RN meter uses the Modbus-RTU
protocol: “9600, 8, n, 1”, where 38400 is the default
baud rate, which can be programmed to change to
1200, 2400, 4800, 9600, etc.; 8 means there are 8 data
bits ;n indicates no parity; 1 indicates 1 stop bit.
错误检测：CRC16（循环冗余校验）
Error detection: CRC16 (Cyclic Redundancy
Check)
DJSF1352-RN 仪表采用 DLT645 协议,支持 07、
97 版本，仪表表号默认为条形码后 12 位，详见菜
单设置。规约支持电压、电流、功率、正反向及组
合电能的读取，复费率电能读取，同时 07 版本规
约还支持编程记录，时间设置的 10 次事件的读

DJSF1352-RN meter adopts DLT645 protocol,
supports 07, 97 version. The meter number defaults to
12 digits after barcode. See menu settings for
details.The protocol supports reading of voltage,
current, power, forward and reverse direction and
combined energy and reading of multi-rate energy. At
the same time, the version 07 protocol also supports
programming records, reading of 10 events of time
setting, and 12 months of multi-rate energy and
demand, 3 times data instantaneous freezing and 12
times frozen data query.
注意：当仪表选配双路直流，第二路直流测量
数据读取时，通讯地址自动在原来地址上加 1。
（modbus 设备地址加 1,645 表号自增 1，合计占 2
个号，相当于 2个表）。
Note: When the meter is equipped with double
DC input channels and the measurement data of
second DC channel is read, the communication
address is automatically added 1 to the original

16
address.(The modbus device address plus 1,645
number is incremented by 1, and it occupies 2
numbers in total, equivalent to 2 meters).
7.2 DLT645 规约 DLT645 protocol
DJSF1352-RN 仪表采用 DLT645 协议,支持 07、
97 版本，仪表表号默认为条形码后 12 位，详见菜
单设置。规约支持电压、电流、功率、正反向及组
合电能的读取，复费率电能读取。
DJSF1352-RN meter adopts DLT645 protocol,
supports 07, 97 version. The meter number defaults to
12 digits after barcode. See menu settings for
details.The protocol supports reading of voltage,
current, power, forward and reverse direction and
combined energy, and multi-rate energy reading.
97 规约只支持基本电参量和电能的读取，97
规约电压最高 9999V，如果额定电流值超过规约的
允许值，随额定电流增大而以 10 倍的规律变小，
额定功率值如果超过规约的允许值，固定变小 1000
倍。
The 97 protocol only supports the reading of
basic electrical parameters and electrical energy. The
voltage of 97 protocol is up to 9999V. If the rated
current exceeds the allowable value of the protocol, it
will become smaller with a factor of 10 with the
increase of the rated current, if the rated power
exceeds the allowable value of the protocol ,it’s fixed
1000 times smaller.
07 规约还支持编程记录，时间设置的 10 次事件
的读取,12 个月的复费率及需量的读取，3次数据瞬
时冻结和 12 次定时冻结的数据查询。
The 07 protocol also supports programming
records, reading of 10 events of time setting, reading of
12-month multi-rates and demand, 3 times
instantaneous frozen data, and 12 times frozen data
queries.

Actual current ratio, 1.2 times rated current within 999A is 1, over 999A is 1000
(02020100 reading value is divided by 1000)

设置的第 1路DO 对应的报警状态，使用第一组报警阈值进行报警，报警信
号源于 DO1 报警源选择，DI 做报警源时双路输入时均可读到，报警状态见
注2
Set the corresponding alarm status of DO1, The first set of alarm thresholds is
used to alarm. The alarm signal originates from the DO1 alarm selection. When
DI is used as the alarm source, it can be read by the double input channels. The
alarm status is shown in Note 2.
