數據更新周期數據更新周期是模塊顯示新數據所用的時間每個通道。對于四個輸入電路，此周期不超過2.4ms；對于一個8輸入電路配置，該周期不超過3.0ms。自動校準

在適當的時間執(zhí)行內部自動校準過程（如有必要）以補償前端漂移的信號處理。自動校準功能采用反饋機制調整參考電壓，以抵消模數轉換器。校準在后臺持續(xù)監(jiān)控并在必要時進行調整。下圖顯示了自動校準所有五個輸入范圍的點數。自動校準點由上的粗點表示坡度線。

自動校準過程使用10 V參考電壓校準模塊。這個參考電壓出廠時預設為10伏（歸零至四位）。它應每年在該領域進行一次調整。

輸入數據轉換輸入模塊對輸入模擬信號進行模數轉換12位分辨率（即4096中的1部分）。這意味著輸出代碼對應于略大于滿量程的0.024%。下圖是用于繪制模擬輸入的粗粒度轉換圖以原始二進制格式輸出到PC的等效數值。這個所示示例顯示了1.25 V（5 V FSR的25%）的輸入電壓和通過455斜線投影的1024個數字（4200的25%）。

使用以下比例方程計算精確值：其中，FSR是模擬輸入（包括雙極）的滿標度范圍，FCR是滿標度原始二進制格式的計數范圍（4200）

Data Update Period The data update period is the time taken by the module to present fresh data for each channel. With four input circuits, this period is no more than 2.4 ms; for an eight input circuit configuration, this period is no more than 3.0 ms. Autocalibration An internal autocalibration process is executed at appropriate times (if necessary) to compensate signal processing for front end drift. The autocalibration function employs feedback mechanisms to adjust the reference voltage to offset gain in the analog to digital converter. Calibration is monitored continuously in the background and adjusted if and when necessary. The following figure shows autocalibration points for all five input ranges. Autocalibration points are indicated by heavy dots on slope line. The autocalibration process uses the 10 V reference to calibrate the module. The reference voltage is factory preset to exactly 10 volts (zeroed to four places). It should be readjusted in the field once per year. Input Data Conversion The input module performs an analog-to-digital conversion of an input analog signal with 12 bit resolution (i.e., 1 part in 4096). This implies that the least significant bit of the output code corresponds to slightly more than 0.024% of full scale. The following illustration is a coarse grain conversion chart for plotting analog input against the equivalent numerical value output to the PC in raw binary format. The example illustrated shows an input voltage of 1.25 V (25% of 5 V FSR) and a numerical count of 1024 (25% of 4200) as projected through the 455 slope line. Calculate exact values using the following proportional equation: Where FSR is full scale range for analog input (including bipolar) and FCR is full count range (4200) in a raw binary format
