可测量和处理来自 2 线、3 线和 4 线电阻式温度检测器的温度信号输入，并输出与来自 RTD 输入的所处理的温度相对应的 4 至 20 mA 电流回路信号，并进行系统级的校准以提高 ADC 和 DAC 精度。(It can measure and process the temperature signal input from the 2-wire, 3-wire and 4-wire resistive temperature detector, and output the 4-20 mA current loop signal corresponding to the temperature processed from the RTD input, and carry out system-level calibration to improve the accuracy of ADC and DAC.)
