In the instrument design and the sensor applications of the industrial automation and control system, 4-20mA current and 1-5V voltage are widely used as signal detection. Paper Introduced a design of high precision 4-20mA, 1-5V standard signal source based on MCU. The system can set the output mode and value, achieve the real-time input and output signal detection and send the result to LCD to display. The system adopts two-wire output, the current and voltage share the same output terminal, and the output mode is set according to different applications. The system has high precision, easy to handle so it can be widely used in industrial automation instrument calibration and so on.
