Isolated two-wire current loop circuit (XTR101, ISO100)
Source: InternetPublisher:toothache Keywords: isolation Updated: 2024/08/29
As shown in the figure, this circuit combines XTR101 with isolation amplifier ISO100 to convert and amplify 4-20mA current into 1-5v voltage output, while isolating the power supply. This circuit has excellent anti-interference characteristics and can be used for long-distance signal transmission or occasions with large on-site interference.
