1. APPLICATION The P30U programmable transducer is designed to convert temperature, resistance, direct voltage and direct current signals into a standard DC voltage or DC current signal. The output signal is galva- nically isolated from the input signal and power supply. The transducer is fi tted with a 2x8 LCD screen.

• RS-485 interface Monitor mode – ability to monitor transmission on RS-485 interface and react to the value of the selected register. • 10/100 BASE-T Ethernet interface (option) • protocol: Modbus TCP/IP, HTTP, FTP, • services: WWW server, FTP server, DHCP client...
4. INSTALLATION 4.1. Mounting method P30 transducers should be mounted on a 35 mm rail bracket according to PN-EN 60715. Dimensions and method of mounting are shown in fi gure 2. Lock Fig.2. Overall dimensions and method of mounting the transducer.
4.2. External connections diagrams Fig.3. External connections diagram of the P30U transducer For the connection of input signals in environments with a high noise level, shielded wires should be used.

LED (power indicator), the transdu- cer displays the type, current firmware version and the serial number. If the transducer is equipped with Ethernet interface (P30U-X2XXXXXX) IP address is displayed after serial number (stored in memory or recei- ved from the DHCP server).
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 dis- play (section 5.5.4).

5.4. Programming transducer parameters Press and hold for about 3 seconds to enter the programming matrix. If access is password protected, transducer will ask for password. If the entered password is incorrect, Err.Code message will be displayed. Correct password enables access to the programming matrix.
