11 Application : The signal isolator RISH Ducer TI 86 (Fig. ) Serves to electrically insulate and analogue DC signal in the range...2 ma which depending on version is then converted to a current or voltage signal (..2 ma or... V ). It operates passively and does not require a seperate power supply, but derives the little auxiliary energy it needs from the DC signal. Its narrow casing is designed for mounting on different on different type of standard rails ( Fig. 2 ). A number of signal isolators can be mounted immediately next to each other and where there are many DC signals to be isolated can form a compact isolator block. Function The DC signal isolator serves to electrically isolate the analog DC signal in the range from ( 4 ) - 2 ma which depending on version is then converted to a current signal ( 4 ) - 2 ma or voltage signal ( 2 ) - V. It does not require a seperate power supply, but derives the little auxiliary power it needs from the DC signal. Features / Benefits Electrically isolated analog DC signals - 2 ma - prevents the transfer of interference voltages and currents. Solves grounding problems in meshed signal networks. No separate power supply needed / saves wiring costs & is easy to install in existing plants. Snaps onto a DIN rail or screw onto a wall or panel- easily adaptable to the mounting facility at the place of installation ( TI 86) Small & compact / Makes best use of the available space. Layout and Mode of Operation Layout and mode of operation The DC signal isolator comprises a DC chopper Z, an isolating stage T, a rectifier G and an oscillator O. The chopper converts the DC input signal E to an AC signal which is transformed with electrical insolation, rectified, smoothed and appears at the output as a DC current signal A (Fig. 3, left). Versions with a DC output voltage signal A have a resistive burden through which the current flows ( Fig. 3, right). The chopper is controlled by the oscillator which obtains its power from the DC signal.

22 Programmable Tap position transducer Rishducer TP-25K Data Sheet Transducer for measuring Tap position Resistance Tap position transducer RISH Ducer TP-25K in housing S7 Page of Version : /4/VII/2/ B

23 Application Tap position transducer RISH Ducer TP-25K coverts resistance to 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. Input measuring range is programmable. It is programmed with the aid of PC and corresponding software. Other parameters relating to the analogue output, transmission mode, operating sense and the open-circuit supervision can also be programmed. The transmitter fulfils all the important requirements and regulation 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 ISO9. Features / Benefits Input tap resistance and measuring range programmed using PC / Simplifies project planning and engineering (the final measuring range can be determined during commissioning). Short delivery times and low stocking levels. Analogue output signal also programmed on the PC (impressed current or superimposed voltage for all ranges between 2 and + 2 ma DC resp. 2 and + 5 V DC) / Universally applicable. Short delivery times and low stocking levels. Electric insulation between measured variable, analogue output signal and power supply / Safe isolation acc. to EN 6 Wide power supply tolerance / Only two operating voltage ranges between 2 and a maximum of 264 V DC/AC. Provision for either snapping the programmable Transducer RISH Ducer TP-25K onto top-hat rails or securing it with screws to a wall or panel Housing only 7.5 mm wide (size S7 housing) / Low space Principal of operation (Fig ) A constant reference current facilitates the measurement of resistance. Depending on the type of connection, either one or more of the terminals,2, 6, and the common ground terminal are used. The constant reference current which is needed to convert a variation of resistance to a voltage signal is available at terminal 6. The internal current source (2) automatically sets the reference current to either 2 or 76µA to suit the measuring range. The corresponding signal is applied to terminal and is used for resistance measurement. An extremely important component of the input stage is the EMC filter which protects the transmitter from interference or even destruction due to induced electromagnetic waves. From the input stage, the measured variable and auxiliary signal (the open-circuit sensor supervision) go to the multiplexer (4), which controlled by the micro-controller (6) applies them cyclically to the A/D converter (5). The A/D converter operates according to the dual slope principle with an integration time of 2 ms at 5 Hz and a conversion time of approximately 38 ms per cycle. The internal resolution is 2 Bit regardless of measuring range. The micro-controller relates the measured variable to the auxiliary signal and to the data which were loaded in the microcontroller s FLASH via the programming connector (7) when the transmitter was configured. These settings determine the type of connections, the measuring range, and the operating sense (output signal directly or inversely proportional to the measured variable). The measured signal is then filtered again, but this time digitally to achieve the maximum possible immunity to interference. Finally the value of the measured variable for the output signal is computed. Depending on the measured variable and the input circuit, it can take.4 to. seconds before a valid signal arrives at the optocoupler (8). The different processing times result from the fact that, for example, a resistance measurement with a four-wire connection and open-circuit sensor supervision requires more measuring cycles than the straight forward measurement of with two wire connection. The main purpose of the opto-coupler is to provide electrical insulation between input and output. On the output side of the optocoupler, the D/A converter (9) transforms the digital signal back to an analogue signal which is then amplified in the output stage () and split into 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 A2. By a combination of programming and setting the 8 DIP switches in the output stage, the signals at A and A2 can be configured to be either a DC current or DC voltage (but both must be either one or the other). The signal A is available at terminals 9 and 4 and A2 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 A2 to a constant value. The latter can be programmed to adopt a preset value between and % or to 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 (2) to flash. Via the opto-coupler (8), it also excites the relay driver (3) which depending on configuration switches the relay (4) to 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 to being able to program the relay to be either energised or de-energised, it can also be set to relay disabled. In this case, an opencircuit 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 to monitor the measured variable in relation to a programmable limit. The normal state of the transmitter is signalled when the green LED (2) 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-button S is for automatically calibrating the leads of a two-wire resistance circuit. This is done by temporarily shorting the resistance sensor and pressing the button for at least three seconds. The lead resistance is then automatically measured and taken into account when evaluating the measure variable. The power supply H is connected to 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 to 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 to supply the relay driver and the other components on the output side of the transmitter. Page 2 of Version : /4/VII/2/ B
