1. APPLICATION
The programmable transducer P30o type has been desig-
ned to convert the number of pulses, frequency, period, running time
and encoder position into a standard direct current or direct voltage.
The transducer has also been fi tted with a signal setting function.
The output signal is galvanically isolated from the input signal and power
supply. The transducer is fi tted with a 2x8 LCD screen.
Features of the P30o transducer:
• 2 independent, universal measurement inputs separated galvanically,
• binary inputs controlling the operation of the main input separated
galvanically from inputs,
• controlling the main counter operation via transducer keypad,
• auto counter resetting at preset value,
• fi ltering input signal used in conjunction with mechanical setters,
• converting measured values into any output signal based on an in-
dividual linear characteristic,
• calculating measured values using one of fi ve implemented mathe-
matical functions,
• calculating measured values based on a 21-point individual charac-
teristics,
• one or two NO (normaly open) relay alarms operating in 6 modes,
• auxiliary power supply 24V DC 30mA switched on/off by software
(options),
• indication of exceeding the alarm values set,
• programming alarm and analog outputs with a reaction to selected
input value

nal memory and on an SD/SDHC card (option),

3. BASIC REQUIREMENTS, OPERATIONAL
SAFETY
The transducer meets the requirements of EN 61010-1 standard
in terms of operational safety.
Safety precautions:
• The assembly and installation of electrical connections must be car-
ried out by a person authorized to install electrical equipment.
• Before switching the transducer on, one must check the correctness
of connections.
• The device is destined to be installed and used in industrial electro-
magnetic environment conditions.
• The building installation should be equipped with a switch
or an automatic circuit breaker located near the device, which should
be easy accessible by the operator and properly marked
• Removal of the transducer housing during the warranty period may
cause its invalidation.

4. INSTALLATION
4.1. Mounting method
P30 transducers should be mounted on a 35 mm rail bracket
according to EN 60715. Dimensions and method of mounting hare
shown in fi gure 2.

4.2. External connections diagrams
Fig. 3. External connections diagram of the P30o transducer
Shielded cables should be used for connecting input signals
in environments with high level of perturbations. Physical measure-
ment inputs have been marked with INP1 and INP2 symbols, these are
the physical transducer inputs corresponding, respectively, to the main
input and the auxiliary input defi ned for the purposes of transducer
confi guration. The main input and the auxiliary input have been divided
into types depending on the measured physical value. An exception
to that are types of inputs from the main input group that physically use
two external input signals: Counter IN1-IN2 and Encoder.
The method of using physical measurement inputs depending
on the selected type of the main input or the auxiliary input has
been shown in table 1. Detailed information on types and functions
of measurement inputs have been discussed in section 5.5.1.

4.3. Connection examples
An example connection between P30o transducer and
inductive sensor with NPN or PNP output type is shown on fi g.
4. The method of connecting the transducer with contactron/re-
lay type outputs is shown on fi g. 5. Examples show the connection
of both main auxiliary inputs for measuring the same signal. Volt-
ages controlling the inputs should be within 5...24 V DC range.

Note: The memory card (option) should be inserted to the transducer
slot with contacts facing down.
LED indicator description:
RX – green diode – Date reception on RS-485 indicator
TX – yellow diode – Date transmission on RS-485 indicator

M – red diode – full internal memory indicator or writing fi le
to SD/SDHC memory indicator, when the internal memory
usage exceeds 95%, the diode is constantly on, if the trans-
ducer operates with an installed memory card, then the LED
fl ashes when Date is being written on the card.
A1 – red diode – indicator of switching on the fi rst alarm
A2 – red diode – indicator of switching on the second alarm
or 24V d.c. power supply
Power indicator – green diode.
5.2. Messages after switching on the power
After connecting external signals and switch the power supply
on which is signalled with a green LED (power indicator), the transdu-
cer displays the type, current firmware version and the serial number.
If the transducer is equipped with Ethernet interface (P30o-X2XXXXXX)
IP address is displayed after serial number (stored in memory
or received from the DHCP server).

- accept key
• enters programming mode (hold for about 3 seconds).
• navigates the menu – level select,
• enters parameter value change mode,
• accepts the changed parameter value,
• changes the content displayed in the lower line of the display
• switching the transducer power supply on while holding this key
enters the software update mode through the RS-485 interface,
connection parameters: rate 9600 kb/s, mode 8N2.
- increase value key
• displays the maximum value of the main input
• enters the parameters group level,
• navigates the selected level
• changes the value of a selected parameter – increase value,
After about fi ve seconds, the transducer automatically
switches to operating mode; it makes a measurement and converts
it into an analog output signal. It displays the measured value
in the top row of the display and auxiliary information in the bottom row
of the display (section 5.5.4). The LED indicator signals the transmis-
sion status on the RS-485 interface, status of the internal memory use
and alarm states. If transducer is equipped with an Ethernet interface,
Ethernet services start-up: WWW server, FTP server, TCP/IP Modbus.
