1. General Information
PMAC735 is a multi-functional power meter, integrating data acquisition and control int o a whole.
It can take the place of numerous meters, relays, transducers, and other components. Besides, it
can be used in electric power systems of various voltage classes.
PMAC735 provides one RS485 communication port, so it can be integrated into any electric
power monitoring system. The management software or other configuration software with which
it is equipped enables the setting to be carried out easily. Furthermore, it provides an optional
PROFIBUS communicati on port, whose 1.5 M co mmunication speed can fully meet the de mand
for obtaining real-time data on the site.
PMAC735 is really a measuring meter based on true effective values, able to carry out accurate
measurement of highly non-linear loads. The complicated sampling technology enables it to
measure true effect iv e val ues up to th e 3 1st harmonic. The us er can re ad r e mot ely s o me do zen s o f
measured values and minimum/maximum va lues on a display screen or via software.
PMAC735 provides multiple extension modules and advanced software functions to meet the
demands of differe nt sites. Its flexible DI/DO configuration facilitates the desig n of the user.
PMAC735 adopts connection realized by terminals that can be pulled out and inserted, thus
facilitating on-site wiring and maintenance. Especially for the parts to which current is inputted,
PMAC735 uses lockable fixation connections to prevent dangers that may be caused by
accidental coming off of connections.

5. Input/output Characteristics (optional)
5.1 Status input
PMAC735A-/B-/E- provides 4 or 8 status input channels, which are used to detect state
information such as breaker position signal s and isolator position signals.
The DC voltage which product provides is not below 30V. On the site, dry nodes or passive
auxiliary nodes can be connected directly. When external nodes are closed, the corresponding
status input channels will be closed.
4 status input signals 8 status input signals
【Attention】
Since there is a power supply available for detection inside the meter, the external nodes cannot
be further conn ected to any another voltage system. Otherwi se, the status inpu t channels will be
burnt down.
53
5.2 Relay output
PMAC735A-/B- provides two relay operation modes. They are remote control and local control.
The action of relay is different in these two modes. So, users should distinguish the relay is in
remote control mode or in local control mode at first.
The default cont rol mode of this product is r emote control. Users can chang e the mode through
communication.
◆ Remote control (external) - The relay is controlled by a PC or PLC by using commands
through communica tion.
◆ Local control (internal) - The relay is controlled by one of the electrical parameters inside
the meter, which serves as the response to the control alarm conditions of a set point.
Once the relay has been in the remote control mode, even though the local control conditions
have been set, the relay will not ope rate. The relay mode must be set at local control mode.
The two relay operation modes are as follows:
◆ Normal:
- Remote control: By receiving a command from a PC or PLC, the relay closes. The relay’s
status will be kept until the PC or PLC gives a release command or the meter is
de-energized.
- Local control: When an alarm signal activating the relay is generated, the relay operates.
The relay will not be released until all the alarm conditions activating the relay disappear or
the meter is de-energized. If the power supply for the meter is resumed and the alarm
conditions still exist, the relay will opera te again.
54
◆ Tim e delay reset
- Remote control: By recei v i n g a co mmand from a PC or PLC, t h e r el ay operates. The rel ay’s
operating status will be kept until a special timer overflows or the meter is de-energized. If,
before the timer overflows, there is a new command that makes the relay operates, the timer
will restart.
- Local control: When an alarm signal activating the relay is generated, the relay operates.
The relay’s operating status will be kept within the period of time for timing. When the
timer overflows, the relay will be released and kept released.
5.3 Pulse outputs
PMAC735E provides two pulse output outlets, one for active energy pulse output and the other
for reactive en ergy pu lse o utp ut . The u ser can sel f- def in e the t ype o f en ergy, and the default t ypes
are active energy input and reactive energy input. The user can also forbid pulse outputs.
A typical wiring mode of external acquisiti on equipment is shown as follows:
55
【Attention】
a. Different pulse acquisition devices have different operating modes. The pulse output
port circuit provided by PMAC735E is adopting the collecting electrode open-circuit mode,
isolated by optically coupled.

.
The pulse outputs of PMAC735E correspond to the signal energy values inputted into the meter,
and they can also be called secondary side energy values. When the user calculates the actual
energy, the pulse outputs should be multiplied by the CT and PT factors. Each pulse does not
represent one kilowatt-hour or kilovar-hour, so the user needs to set a reasonable pulse constant.
The maximum setting range is between 1000 and 40000. The maximum pulse speed does not
exceed 200 ms, which means that, when the accumulated energy of the meter is 1 kwh, the
number of pulse outputs is N. Please note that the energy values here are all secondary side data.
Therefore, when t h er e ar e PTs and CTs, the pri mary side energy corr esp on ding to N puls es sh ould
be 1 kwh×PT×CT .
The maximum settable scope of 220V/5A range is 1000 to 5000, those of 220V/1A and 100V/5A
ranges are both 100 0 to 20000, and that of 100V/1A range is 1000 to 40000.
The step lengths are a ll 100.
56
5.4 Analog output
PMAC735 can provide one optional 4-20 mA analog output, supporting the access of the DCS
system. The user can, through the communication interface, set the parameter value
corresponding to the analog output. The maximum load resistance of the interface should not
exceed 500 Ohms.
On some sites, d ue to different trans missi on cabl es or load ing co nditi ons, th e analo g ou tput at t he
high end appears to be non-linear. PMAC735 provides a settable magnification factor. By
modifying the magnification factor, the user can adjust the proportion fact or of the output curve.
The figure below shows the analog output characteristic curve, and the magnification factor is λ:

6. Alarm System (optional)
PMAC735A-/B- provides multiple relay alarm outputs, any of which can work independently and
support the user’s programming.
Any of the relay output that has been set at local control mode corresponds to alarm about voltage
or current. Each alarm needs 5 parameters programmed, as shown in the table below:
Operation-object
0 – Prohibit
1 - Maximum value of three-phase voltage
2 - Minimum value of three-phase voltage
3 - Maximum value of three-phase line voltage
4 - Minimum value of three-phase line voltage
5 - Maximum value of three-phase current
6 - Minimum value of three-phase current
Operation upper

0% - 120% of rated value
Operation time
delay
0 – 1200s; 0 means that the relay operates immediately.
Return time 0 – 1200s; 0 means no retu rn.
For example, th e user needs to monitor wheth er there is under-voltage in th ree phases. I f there is
under-voltage in any phase, alarm will be given immediately until normal voltage is resumed.
Then, programming can be carried out according to the following settings:
Operation-object: Minimum value of three-phase volta ge
60
Operation upper limit value: 120
Operation lower limit value: 80 (it is assumed here that under-voltage refers to a voltage lower
than 80% of the rated voltage)
Operation time: 0 s
Return time: 0 s
Other values can be set according to the above procedure, and descriptions will not be given one
by one.
61
7. SOE /Event Log (optional)
PMAC735 provides optional function of recording up to 50 SOE events, and the records can be
kept for more than 10 years.
The SOE recording function can record the displacements of switch contacts. When an event
occurs, the meter will automatically record the type of the event such as closing of status 1. At the
same time, the year, month, day, hour, minute, second, millisecond when the event occurs will be
recorded precisely, and the resolution is 2 ms.
Users can read all the SOE records through communication. For details, refer to “SOE” (event
log).
A standard structure of SOE event data is as follows:
No. of the relative byte Definition Description

The basis reference of the UNIX clock is 00:00:00 January 1, 1970 (Greenwich Mean Time). For
time conversion, please pay attention to the time difference of your time zone. For example, there
is an 8-hour time difference between the time of Beijing time zone and the standard UN IX.

8. Communication Protocol
8.1 Overview
PMAC735 main unit provides the MODBUS-RTU communication protocol, 8 data bits, 1 stop bit,
without check bi t. Each frame d ata packag e contain s the addres s field, fun ctional cod e field, d ata
field, and check field. The maximum length of each data package is 95 bytes.
The length of the ad dress fiel d is 1 byte, and the conten t is slave st ation addr ess. The range o f an
effective slave station address is 1 to 247. If the slave station receives a package in which the
address field information conforms to its own address, it should execute the commands contained
in the package. In the package to which the slave station responds, the field is its own address.
The length of the functional code field is 1 byte, used to tell the slave station to execute what
operations. The functional codes supported by PMAC735 are listed in the table below:
Functional code Meaning Function
0x03 Read register
Obtaining one or more than one current register
values inside the current PMAC735.
0x10 Setting register
Writing the designated values into one or more than
one registers inside PMAC735.
0x05 Relay control Controlling a relay inside the current PMAC735.
The length of the data field is not fixed, and it will be defined according to the specific function.
The data in the data field adopts the BIG INDIAN mode, with the high bytes in front and the low
bytes at the back.
The check field adopts 16-bit CRC check codes. The transmitting device should make CRC
calculation for each of the data inside the package, and the final results will be stored in the check
63
field. The receiving device should also make CRC calculation for each of the data (except the
check field) inside the package and compare the results with the check field. Only the same
package will be accepted.
8.2 Abnormal response
If the main station sends an illegal package or asks for an invalid data register, an abnormal data
response will be generated. This abnormal data response is composed of the slave station address,
functional code, trouble code, and check field. When the highest bit of the functional code field
is 1, it means that the data frame is an abnormal response at this time. The table below describes
the meanings of abnormal functional codes:
Trouble code Description
01H Illegal operation functional code received.
02H Illegal register oper ation or over-long data received.
64
8.3 Relay control
The functional code is 05H .
In this mode, only individual relay can be controlled. The status of a relay can be obtained by
reading the relay status register. The relay address starts from 0 in the register. The address of
relay 1 is 0, and the rest may be deduced by analogy. Sending sexadecimal FF 00 closes a relay
and sending sexadec imal 00 00 releases a relay. All the other values will be invalid.

INT16 Signed 16-digit integer
LUINT32 Unsigned 32-digit integer
LINT32 Signed 32-digit integer
WORD16
Bit denotation word, applicable to on-off and relay status.
D0 refers to the first on-off or relay channel.
D1 refers to the second on-off or relay channel.
The rest bits may be deduced by analogy.
Bit 0 refers to “off”, and bit 1 refers to “on”.
8.7 Calculation factors
Due to the restriction of the value ranges, many of the data registers of PMAC735 use calculation
factors. This means that, if the user wants to obtain the actual values, the corresponding
calculation factors must be multiplied.
For example, th e calculati on factor o f the power f actor regis ter is 0.00 1. When the v alue read by
the user at this time is 892, the current power fa ctor will be: 892 × 0.001 = 0.892.
68
8.8 Communication values and actual values
To ensure that the meter keeps adequate accuracy bits when transmitting data, some of the
real-time data registers of PMAC735 adopt some special processing methods, as shown in the
table below:
No. Content Communication value Actual value
