SUNYUAN SY C-A-P-O series converter is a kind of 2-wire 4-20mA Differential Signal Acquisition Conditioner IC, it contains an internal differential signal acquisition, conditioning and conversion coupled circuits. Standard input equivalent resistance enables the IC collect differential signals from sensor to meet the user's requirements in MCU applications. (± 9 ~ ± 15V) Wide range power supply or single power supply. It can meet the temperature, humidity, vibration and other industrial site in harsh environment. SY C-A-P-O is easy to use, do not take any regulation loop that can achieve the required accuracy, to achieve the two-wire 4-20mA signal transmission and transmitter functions.
