  • Page 5: Application

    1. APPLICATION The P20 programmable transducer is designed to convert temperature, resistance, voltage from a shunt and standard signals into a constant- current or constant-voltage standard signal. The output signal is galvanicaly isolated from the input signal and supply. The transducer compensates automatically the resistance of wires in...

  • Page 6: Operational Safety

    3. OPERATIONAL SAFETY In the safety service scope, the transducer meets to requirements of the EN 61010-1 standard. Observations concerning the operational safety All operations concerning transport, installation, and commissioning as well as maintenance, must be carried out by qualified, skilled personnel, and national regulations for the prevention of accidents must be observed.

  • Page 7: Installation

    4. INSTALLATION 4.1. Fitting way P20 transducers are designed to be mounted on a 35 mm rail accor- ding to EN 60715. Housing dimensions are: 22.5 x 120 x 100 mm. On the transducer outside, there are screw or self-locking terminal strips, which make possible the connection of external wires with a 2.5 mm...

  • Page 10: Transducer Configuration By Means Of The Econ Software

    One must connect the PC computer through the PD14 programmer and configure the connection choosing Communication -> Serial port from the menu (for the P20 transducer, we choose the address 1, baud rate 9600 kb/s, the mode RTU 8N2 and the appropriate port COM under which the controller of the PD14 programmer has been installed).

    5.1.1 Configuration of the transducer input type In the parameter group Input configuration there are 3 expandable lists available, by means of which you can select the input type, measuring range and measurement averaging time. The changes must be confirmed by clicking the Save button. Fig.

  • Page 12: Configuration Of The Individual Analog Output Characteristic

    5.1.2. Configuration of the analog output characteristic The P20 transducer enables the conversion of measured values into an output signal on the base of the individual linear characteristic of the analog output. On the base of given by the user coordinates of two points, the transducer determines (from the system of equations) coefficients a and b of the individual characteristic.
