這SCXI-1102B(零件號:776572-02B)具有截止頻率為200 Hz的三極低通濾波器、32個差分通道和DC輸入耦合。該模塊還有一個用于溫度測量的冷結補償傳感器。該模塊的輸入可以多路復用為一個輸出，進而驅動一個DAQ器件通道。

這SCXI 1102B當增益為1時，差分輸入信號范圍為10V；當增益為100時，差分輸入信號范圍為0.1 V。差分輸入范圍是正負通道輸入之間的最大可測量電壓差異。的共模輸入信號范圍NI SCXI-1102B電壓輸入模塊正或負通道輸入的共模輸入范圍是實現(xiàn)精確測量的最大輸入電壓。上的每個頻道SCXI-1102B模塊配有輸入保護電路，可承受無意施加的42 VAC峰值或60 VDC最大值的電壓。用戶應記住，超過差分或共模輸入通道范圍將導致信號測量不準確。它還會導致連接的E/M系列DAQ儀器的建立時間增加。

上的輸入信號NI SCXI-1102B電壓輸入模塊可以以地為基準或浮動。在連接熱電偶或其它信號之前，用戶必須確認它是以地為參考還是懸空。浮動信號必須以地為參考，通過偏置電阻將負通道輸入連接到機箱地。第二種選擇是利用某些端子板附帶的偏置電阻，如SCXI-1303。

The SCXI-1102B (Part Number: 776572-02B) has a three-pole lowpass filter with a 200 Hz cutoff frequency, 32 differential channels, and DC input coupling. This module also has a cold-junction compensation sensor for temperature measurements. The inputs on this module can be multiplexed to one output, which in turn drives one DAQ device channel.

The SCXI 1102B has a differential input signal range of ±10 V when utilizing a gain of 1 or ±0.1 V when utilizing a gain of 100. The differential input range is the greatest measurable voltage variance between the positive and negative channel inputs. The common-mode input signal range of the NI SCXI-1102B Voltage Input Module is ±10 V. The common-mode input range for positive or negative channel input is the greatest input voltage that leads to an accurate measurement. Every channel on the SCXI-1102B module comes with input protection circuitry to endure the unintentional application of voltages to ±42 VAC peak or 60 VDC maximum. The user should keep in mind that going above the differential or common-mode input channel ranges will lead to an inaccurate signal measurement. It can also result in an increased settling time prerequisite of the linked E/M Series DAQ instrument.

The input signals on the NI SCXI-1102B Voltage Input Module 

The input signals on the NI SCXI-1102B Voltage Input Module can be ground-referenced or floating. Prior to linking the thermocouple or another signal, the user must confirm if it is ground-referenced or floating. Floating signals must be ground-referenced by linking the negative channel input to chassis ground via a bias resistor. The second option is to utilize the bias resistors included with certain terminal blocks, such as the SCXI-1303.
