這SCXI-1313(零件號:777687-13)是一個屏蔽接線盒專為SCXI-1125模塊的最佳使用而設(shè)計。上的每個頻道SCXI 1313具有一個精密的100:1電阻分壓器，用戶可以使用SCXI-1125測量最大300 VRMS或300 VDC的電壓。對于低壓測量應(yīng)用，用戶可以單獨旁路分壓器。上有18個螺絲端子NI SCXI-1313接線板這允許簡單信號連接。一對螺絲端子連接到SCXI-1125模塊底盤接地。其他八對螺絲端子將信號連接到八個模擬輸入。

用戶可以在上使能或禁用衰減器倪SCXI 1313通過在Measurement & Automation Explorer中更改端子板的標準配置設(shè)置。另一種選擇是讓用戶改變其應(yīng)用中的輸入限值范圍。如果用戶正在使用虛擬通道，則使用虛擬通道配置器中配置的輸入限值來正確指定衰減電路。

這SCXI-1313接線板具有一個溫度傳感器，可在0至50°c的溫度范圍內(nèi)輸出1.91至0.65 V的電壓，如果用戶使用LabVIEW，他們可以利用轉(zhuǎn)換熱敏電阻讀數(shù)。用戶應(yīng)該利用許多樣本來獲得盡可能精確的讀數(shù)。嘈雜的環(huán)境需要大量的樣本來確保精確度。

The SCXI-1313 (Part Number: 777687-13) is a Shielded Terminal Block designed for optimal use with the SCXI-1125 module. Every channel on the SCXI 1313 has a precision 100:1 resistive voltage divider that the user can utilize to measure voltages to 300 VRMS maximum or ±300 VDC with the use of the SCXI-1125. For low-voltage measurement applications, the user can separately bypass the dividers. There are 18 screw terminals on the NI SCXI-1313 Terminal Block which allow simple signal connection. One pair of screw terminals links to the SCXI-1125 module chassis ground. The other eight pairs of screw terminals link signals to the eight analog inputs.

The user can enable or disable the attenuator on the NI SCXI 1313 by altering the standard configuration settings for the Terminal Block in Measurement & Automation Explorer. The other option is for the user to alter the input limit ranges in their application. If the user is utilizing virtual channels, then the input limits configured in the virtual channel configurator are utilized to designate the attenuation circuitry correctly.

The SCXI-1313 Terminal Block has a temperature sensor that can output 1.91 to 0.65 V in a temperature range of 0 to 50 °C. If the user is utilizing LabVIEW, they can take advantage of the Convert Thermistor Reading. The user should utilize many samples to acquire the most precise reading possible. Loud conditions necessitate a larger number of samples to ensure preciseness.
