1 Voltage Transducer for DC Voltages TERFACE Data Sheet 000_en_0 PHOENIX CONTACT - /00 Description The MCR voltage transducer measures DC voltages in several signal ranges from 0... ±0 V DC to 0... ±0 V DC and converts them to standardized analog signals. DC voltages can be processed with both positive and negative polarity. The input voltage ranges listed at input terminal blocks to can be varied by ±0% using a calibration potentiometer. The voltage transducer is calibrated by default to 0... ± V input and 0... ±0 V output and is ready for operation when delivered. To use the device with other input or output variables, carry out a ZERO/SPAN adjustment using the potentiometer on the front.. Features -way electrical isolation True r.m.s. value measurement Adjustable voltage ranges ZERO/SPAN adjustment ±0%. Method of Operation The input circuit divides the DC voltage at terminal blocks to. The resulting signal is electrically isolated and transmitted to the output circuit and is available at the output as a standardized analog signal.. Field of Application When using the voltage transducer, please ensure that the potential difference between terminal blocks to to ground potential PE or terminal block 8 to ground potential PE U does not exceed ±0 V (this condition applies to circuits that are not grounded). In DC voltage networks, this potential difference must not exceed U = ±00 V (this condition applies to circuits that are grounded). When these conditions are met, safe isolation is ensured between input, output, and supply. Make sure you always use the latest documentation.

The module is calibrated by default to 0... ± V input and 0... ±0 V output. There are two potentiometers on the front of the module for the adjustment: ZERO: Zero point adjustment SPAN: Final value adjustment 9. Zero Point Adjustment (ZERO) Connect a calibration device to the input terminal blocks (U ( - ) and D) and specify a voltage of 0 mv. Set the output signal value using the ZERO potentiometer: Voltage output (0 ±0 V): U = 0 V Current output (0 ±0 ma): I = 0 ma 9. Final Value Adjustment (SPAN) Use the calibration device to specify the maximum voltage used within the input voltage range (see "Selecting the Input Voltage Range" on page ). Set the output signal value (U = 0 V or I = 0 ma) using the SPAN potentiometer. 000_en_0 PHOENIX CONTACT GmbH & Co.
