1 , Voltage Measuring Transducer for AC Voltage MCR-VAC-UI-0-DC. Description -way electrical isolation TRMS measurement Adjustable voltage ranges / adjustment ±0% Voltage transducers measure AC voltages in several signal ranges from 0 V AC to 0 0 V AC and convert them into standardized analog signals. The input voltage ranges of input terminals can be adjusted by ±0% using an adjustment potentiometer. The input, output, and supply are electrically isolated from one another. Upon delivery, the voltage transducer is set to 0 V AC input and 0 0 V DC output and is ready for operation. If you set the device to other input/output values you must carry out a / adjustment using the potentiometer on the front plate.. Method of Operation The input circuit divides the AC voltage at terminals. The resultant signal is transmitted electrically isolated to the output circuit. This forms the r.m.s. value and provides a standardized analog signal at the output.. Area of Application 99, When using the voltage transducer, ensure that the potential difference between terminal and ground potential PE, and terminal and ground potential PE does not exceed U rms = V (prerequisite for ungrounded circuits). In AC voltage networks, this potential difference should not exceed U rms = 0 V (prerequisite for grounded circuits). If all of these conditions are met, safe isolation is provided between the input, output, and supply. Headquarters: Phoenix Contact GmbH & Co.
