The output signal is galvanically isolated from the input signal and the power supply.
P30U has programmable measurement and auxiliary functions. Parameters programming can be realized using buttons or RS-485 interface and LPConfig software.
Features of P30U parameters and functions:
- input: programmable
- thermocouples, resistance thermometers,
- 0...4/20 mA, +/- 20mA
- -5...20mV, +/- 75mV; +/-200mV
- 400, 2000, 5500 ohm
- RS485 Master or Slave
- output: programmable
- analog (current or voltage)
- 1 or 2 x relays
- digital RS-485
- display: LCD 2 x 8 characters with backilit,
- supply: 85..253 V a.c./d.c. or 20...40 V a.c./20...60 V d.c.
- 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,
- additional 24V DC 30mA power supply switched on/off like an alarm (option)
- indication of exceeding the alarm values,
- programmable alarm and analogue 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 SD/SDHC card (option),
- internal memory with the capacity of 534336 records,
- automatic decimal point setting,
- preview of configured parameters,
- access to parameters locked by a password,
- programming the measurement averaging time.
