2 Application The universal transmitter RISH Ducer V 64 (Figures and ) converts the input variable a DC current or voltage, or a signal from a thermocouple, resistance thermometer, remote sensor or potentiometer a proportional analogue output signal. The analogue output signal is either an impressed current or superimposed voltage which is processed by other devices for purposes of displaying, recording and/or regulating a constant. A considerable number of measuring ranges including bipolar or spread ranges are available. Input variable and measuring range are programmed with the aid of a PC and the corresponding software. Other parameters relating specific input variable data, the analogue output signal, the transmission mode, the operating sense and the open-circuit sensor supervision can also be programmed. The open-circuit sensor supervision is in operation when the Rish Ducer V 64 is used in conjunction with a thermocouple, resistance thermometer, remote sensor or potentiometer. The transmitter fulfils all the important requirements and regulations concerning electromagnetic compatibility EMC and Safety (IEC resp. EN 6 ). It was developed and is manufactured and tested in strict accordance with the quality assurance standard ISO 9. Production QA is also certified according guideline 94/9/EG. Features Input variable (temperature, variation of resistance, DC signal) and measuring range programmed using PC / Simplifies project planning and engineering (the final measuring range can be determined during commissioning).

The input stage includes potential dividers and shunts for this purpose. A constant ference current facilitates the measurement of resistance. Depending on the type of measurement, either one or more of the terminals,, 6, 7 and and the common ground terminal are used. The constant reference current which is needed convert a variation of resistance such as that of a resistance thermometer, remote sensor or potentiometer a voltage signal is available at termina 6. The internal current source () aumatically sets the reference current either 6 or 38uA suit the measuring range. The corresponding signal is applied terminal and is used for resistance measurement. Terminal is used for active sensors, i.e. thermocouples or other mv generars which inject a voltage between 3 and 3 mv. Small currents from the open-circuit sensor supervision (3) are superimposed on the signals at terminals and in order monir the continuity of the measurement circuit. Terminal is also connected the cold junction compensation element which is a Ni resisr built in the terminal block. Terminals 7 and are also input terminals and are used for measuring currents and for voltages which exceed 3 mv. An extremely important component of the input stage is the EMC filter which protects the transmitter from interference or even destruction due induced electromagnetic waves. From the input stage, the measured variable (e.g. the voltage of a thermocouple) and the two auxiliary signals (cold junction compensation and the open-circuit sensor supervision) go the multiplexer (4), which controlled by the micro-controller (6) applies them cyclically the A/D converter (5). The A/D converter operates according the dual slope principle with an integration time of ms at 5 Hz and a conversion time of approximately 38 ms per cycle. The internal resolution is Bit regardless of measuring range. The micro-controller relates the measured variable the auxiliary signals and the data which were loaded in the microcontroller s EEPROM via the programming connecr (7) when the transmitter was configured. These settings determine the type of measured variable, the measuring range, the transmission mode (e.g. linearised temperature/thermocouple voltage relationship) and the operating sense (output signal directly or inversely proportional the measured variable). The measured signal is then filtered again, but this time digitally achieve the maximum possible immunity interference. Finally the value of the measured variable for the output signal is computed. Apart from normal operation, the programming connecr is also used transfer measured variables on-line from the transmitter the PC or vice versa. This is especially useful during commissioning and maintenance. Depending on the measured variable and the input circuit, it can take.4. seconds before a valid signal arrives at the opcoupler (8). The different processing times result from the fact that, for example, a temperature measurement with a fourwire resistance thermometer and open-circuit sensor supervision requires more measuring cycles than the straight forward measurement of a low voltage. The main purpose of the op-coupler is provide electrical insulation between input and output. On the output side of the opcoupler, the D/A converter (9) transforms the digital signal back an analogue signal which is then amplified in the output stage () and split in two non-electrically isolated output channels. A powerful heavy-duty output is available at A and a less powerful output for a field display unit at A. By a combination of programming and setting the 8 DIP switches in the output stage, the signals at A and A can be configured be either a DC current or (but both must be either one or the other). The signal A is available at terminals 9 and 4 and A at terminals 8 and 3. If the micro-controller (6) detects an open-circuit measurement sensor, it firstly sets the two output signals A and A a Page of 5 Version : /4/VII//B

3 constant value. The latter can be programmed adopt a preset value between and % or maintain the value it had at the instant the open-circuit was detected. In this state, the microcontroller also switches on the red LED () and causes the green LED () flash. Via the op-coupler (8), it also excites the relay driver (3) which depending on configuration switches the relay (4) its energised or de-energised state. The output contact is available at terminals 3, 4 and 5. It is used by safety circuits. In addition being able program the relay be either energised or de-energised, it can also be set relay disabled. In this case, an open circuit sensor is only signalled by the output signal being held constant, the red LED being switched on and the green LED flashing. The relay can also be configured monir the measured variable in relation a programmable limit. The normal state of the transmitter is signalled when the green LED () is continuously lit. As explained above, it flashes should the measurement sensor become open-circuit. It also flashes, however, if the measured variable falls % below the start of the measuring range or rises % above its maximum value and during the first five seconds after the transmitter is switched on. The push-butn S is for aumatically calibrating the leads of a two-wire resistance thermometer circuit. This is done by temporarily shorting the resistance sensor and pressing the butn for at least three seconds. The lead resistance is then aumatically measured and taken in account when evaluating the measure variable. The power supply H is connected terminals 5 and on the input block (5). The polarity is of no consequence, because the input voltage is chopped on the primary side of the power block (6) before being applied a full-wave rectifier. Apart from the terminals, the input block (5) also contains an EMC filter which suppresses any electromagnetic interference superimposed on the power supply. The transformer block (7) provides the electrical insulation between the power supply and the other circuits and also derives two secondary voltages. One of these (5 V) is rectified and stabilised in (8) and then supplies the electronic circuits on the input side of the transmitter. The other AC from block (7) (6 V / 8 V) is rectified in (9) and used supply the relay driver and the other components on the output side of the transmitter.
