Two make the 4-20mA electric current link isolation wiring diagram

Origin: Input time: 07-06-04 00:33:36English version

>ISO 1,003 4-20mA electric current link isolation recuperating is the monolithic two systems isolation connection chip, this chip interior contains has an electric current signal tone circuit, the photoelectricity coupling isolation transfer network and the demodulation electric circuit. This chip has 4-20mA the power line voltage scope width (16.5V-36V), the input equivalent resistance is small, linear higher characteristic. This chip may provide 5V/3.5mA the isolation voltage output, the 2.5V datum power source. The input signal voltage is 0-0.8V, corresponds 输入�?in the electric current ring circuit the electric current change. The input and the output side width crawls the electricity to be away from and the internal special insulation isolation measure causes this chip to be possible to achieve the 2500VAC insulation voltage.
