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
• (main input, auxiliary input or RTC),
• real time clock (RTC) with independent battery supply,
• recording the input signals in programmed time periods in the inter-
nal memory and on an SD/SDHC card (option),
• internal archive memory with 534336 record capacity,
• automatic decimal point setting,

• preview of preset parameters,
• password protected parameter change,
• RS-485 interface support with the MODBUS protocol in RTU mode,
• programmable averaging time,
• SD/SDHC memory cards support – compatible with FAT and FAT32
fi le system (option),
• 10/100 BASE-T Ethernet interface (option)
- protocol: Modbus TCP/IP, HTTP, FTP,
- services: WWW server, FTP server, DHCP client.

• plug-able screw terminal blocks 4 pcs.
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.
