The AV-1I module is designed to measure voltage and convert the measured quantity to a unified analog output current signal in the range of 4-20 mA. Transducer The transducer continuously measures the value of the input voltage (AC or DC voltage circuit). The measured voltage value is proportionally converted to the output DC signal Iout in the range of 4-20 mA, which is equivalent to the measuring range of 0-400V. The transducer allows you to measure the true RMS value of DC and AC voltage with an amplitude not exceeding 400V (which corresponds to approx. 285V RMS value of undisturbed sinusoidal voltage). The transducer measures the rms value of the True RMS voltage, which guarantees high measurement accuracy also with distorted waveforms. The signal output of the module is protected by an anti-interference filter that eliminates network interference affecting the accuracy of the transmitted signal. This allows the use of signal cables up to 300m long.
