P30U-09A/1
USERS MANUAL
1. Application
The P30U programmable transducer is designed to convert temperature,
resistance, voltage, standard voltage and current signals into a standard
DC voltage or DC current signal. The output signal is galvanically isolated
from the input signal and the power supply.
The transducer display is a 2x8 LCD.
Features of the P30U transducer:
conversion of the measured value into any output signal on the basis
of the individual liner characteristics,
conversion of the measured value by means of one of five
implemented mathematical functions,
conversion of the measured value on the basis of 21-point individual
characteristics,
one or two relay alarms with a closing contact working in 6 modes,
additional 24V DC 30mA power supply switched on/off by a program
(option)
indication of exceeding the alarm values set,
programming the alarm and analog outputs with a reaction to the
selected input value (main input or RTC clock),
real time clock with a clock power supply backup function in case of a
transducer power supply loss,
recording the signal input in programmed time periods in the internal
memory and on an SD/SDHC card (option),
archive internal memory with the capacity of 534336 records,
automatic decimal point setting,
view of parameters set,
locking entered parameters by a password,
supporting RS-485 interface with the MODBUS protocol in RTU
mode,
programming the measurement averaging time,
supporting SD/SDHC cards – FAT and FAT32 file system is
supported,
RS-485 Master mode – an option to poll a single device,
RS-485 Monitor mode – an option to monitor transmission on RS-485
interface and react to the value of the selected register.
