1. Application
Pro rammable transducer P30H is suited for volta e, current
(volta e measurement from a shunt) and power measurement in d.c.
circuits and for conversion of measured value into a standard d.c. and
a.c. si nal. Output si nal is alvanically insulated from input si nal and
power si nal. Transducer uses 2x8 characters LCD.
Characteristics of P30H Transducer:
●conversion of measured values into an output si nal on the base of
the individual linear characteristic,
●one or two relay alarms with the n/o contact operatin in 6 modes,
●24 VDC 30 mA auxiliary power turned on/off accordin to pro ram
(optional)
●si nalin of the set alarm values trippin ,
●pro rammin of alarm output and analo outputs reactin to the
selected input value,
●real time clock with the clock power support function in case of the
transducer power failure,
●input si nal re istration in the internal memory and SD/SDHC cards
within the pro rammed time intervals (optional),
●internal memory with 534336 record capacity,
●automatic decimal point set,
●set parameters display,
●password protection for the input parameters,

P30H-09B 4 User's manual
●compatibility with RS-485 interface with MODBUS protocol, in RTU
mode,
●measurement avera in time pro rammin ,
●SD/SDHC card use – FAT and FAT32 system compatibility,
●Master RS-485 mode – 1 device query,
●Ethernet interface10/100 BASE-T (optional)
◦protocol: Modbus TCP/IP, HTTP, FTP,
◦services: web server, FTP server, DHCP client
The values measured and calculated by the transducer:
volta e+ rescalin constant
current (as measured volta e at the shunt ± 150 mV) + rescalin
constant
power
volta e difference in time 5 s, 30 s, 1 min, 5 min, 15 min (dU)
current difference in time 5 s, 30 s, 1 m, 5 m, 15 m (dI)
avera ed volta e (e .15 min.)
avera ed current (e .15 min.)
avera ed power (e .15 min.)
time in seconds
time in hours and minutes
char e capacity in Ah
imported ener y
exported ener y
maximum and minimum values.
Transducer allows for the use of volta e and current rescalin
constants, which will be included in the measurement and calculation
of all measurement values. Value up rade time does not exceed 1
second. All values and confi uration parameters are available throu h
RS-485 and Ethernet (Modbus protocol) (option).

3. Basic requirements, operational safety
In the security scope, the transducer meets the requirements of the EN
61010-1 standard.
Comments concerning safety
●Assembly and installation of the electrical connections should
conducted only by people authorised to perform assembly of electric
devices.

P30H-09B 6 User's manual
●Always check the connections before turnin the transducer on.
●The transducer is desi ned to installation and usa e in the industrial
electroma netic environment.
●A switch or a circuit-breaker should be installed in the buildin or
facility. It should be located near the device, easily accessible by the
operator, and suitably marked.
●Removal of the transducer housin durin the warranty period voids
the warranty.

4. Installation
4.1. Mounting
The P30 transducer are desi ned for installation on a 35 mm rail
acc. to EN 60715. Overall dimensions and mountin is shown in Fi ure 2.
Fig.2 Overall dimensions and mounting of the transducer.
The output si nals are alvanically isolated from the input si nals and
power supply.
The meter housin is made of plastic. On the outside two clampin
strips that can accommodate cables up to 2.5 mm2 in diameter.

Note!
If you need to measure voltages higher than 300 d.c., must use an external additional
resistor type D5 / 1 (600 ) or D5 / 2 (1000 )
For the measured voltage range 300...600
P30H set with additional resistor D5 meets the
requirements:
- CAT III,
- basic isolation between input circuits (terminals
1-4) and other circuits ( 60s /3,51k a.c. )
For the measured voltage range
600...1000 P30H set with additional resistor D5
meets the requirements:
- CAT III,
- basic isolation between input circuits (terminals
1-4) and other circuits ( 60s /3,51k a.c. )

5.2. Power-on messages
After connectin the external si nals and turnin the power on
accompanied by turnin the reen LED (power indicator) on, transducer
displays the type, current software version and the serial number. If the
transducer is equipped with Ethernet interface (P30H-XX2XXXXXXX),
then after displayin the serial no., the device displays also the IP
address saved in memory or received from DHCP server.
