Method of Operation The analog input signal of the temperature sensor is digitized with a -bit resolution and then supplied to a microcontroller. The microcontroller forms a digital output value in line with the temperature from the input signal. This is supplied via optocouplers to a /A converter after electrical isolation. The corresponding output signals are realized using a subsequent voltage or current level (e. g. 0...0 V, 0...0 ma). The microcontroller has an integrated memory in which the program sequence for the measured value calculation is stored. The user-specific parameters are stored in an EEPROM (electrically erasable programmable read-only memory). The programmed data remains in the memory even after the supply voltage has been disconnected. Connections Thermocouples Simple temperature measurement For temperature measurements with the thermocouples described on page, wire terminals and of MCR-T-UI. Note the polarity of the sensor ( "+" input; " " input). ifferential temperature measurement To measure temperature differentials with only one temperature measurement converter, the MCR-T-UI offers the option of connecting two thermocouple sensors of the same type in series and laying the two remaining branches to terminal points and. The connection ends of the two thermocouples can be fixed to terminal points and (see corresponding circuit diagram on page ). The differential temperature measurement can only be set using the configuration software MCR/PI-CONF-WIN because the internal cold junction compensation must be switched off for this. Resistance Thermometer For temperature measurements with the resistance thermometers described on page, wire the following terminal points depending on the connection method used (see corresponding block diagram on page ): and with -wire technology, and with -wire technology,, and with -wire technology Measurement of mv Voltages Voltages in the range of -0...+00 mv are measured at terminals and where is the "+" input and the " " input. Measurement of Resistance To measure differing resistance between 0 Ω and kω, terminal points and are used. The connection is made using -wire technology. Evaluation of Potentiometer Settings To evaluate potentiometers up to kω, terminals and are connected with the external cables and terminal is connected with the loop cable. Switching Output The PNP transistor switching output switches the supply voltage U B when the programmed switching conditions are met from V on terminal!. The transistor output should only be loaded with a maximum of 00 ma. A suppressor diode protects this output from fast transients.
