這倪SCXI-1306(零件號(hào):779698-01)是為了與SCXI-1503 RTD模塊。這接線盒被屏蔽以允許快速、簡(jiǎn)單的信號(hào)連接，并且容易安裝到模塊的前面。這SCXI 1306有16對(duì)用于差分輸入信號(hào)的螺絲端子和另外16對(duì)用于電流激勵(lì)信號(hào)的螺絲端子。

這國(guó)家儀器公司SCXI-1306接線板可以對(duì)傳感器進(jìn)行2線、3線和4線電阻測(cè)量，包括RTD和熱敏電阻。每個(gè)通道都可以配置為電壓或電阻測(cè)量。每個(gè)通道有兩個(gè)開關(guān)，可用于選擇測(cè)量類型。此外，16個(gè)差分模擬通道可以用來完成浮空和接地電壓測(cè)量。熱電偶測(cè)量是浮動(dòng)測(cè)量的特征。對(duì)于浮動(dòng)或接地電壓測(cè)量，用戶可以將電壓源連接到模擬輸入螺釘端子。然后，用戶可以根據(jù)測(cè)量的信號(hào)類型修改開關(guān)位置。當(dāng)用戶測(cè)量浮動(dòng)信號(hào)時(shí)，他們可以將負(fù)輸入連接到SCXI-1503 RTD模塊的內(nèi)部接地。

的一個(gè)有益特性是鎳SCXI-1306接線板集成的溫度傳感器。該特性可用于熱電偶冷結(jié)補(bǔ)償。為確保精確的冷結(jié)補(bǔ)償，用戶不得將SCXI機(jī)箱放在任何極端溫差附近。NI還建議對(duì)大量樣本進(jìn)行平均，以獲得精確讀數(shù)。

The NI SCXI-1306 (Part Number: 779698-01) was created to be used with the SCXI-1503 RTD Module. This Terminal Block is shielded to allow swift, simple signal connections and mounts easily to the front of the module. The SCXI 1306 has 16 pairs of screw terminals for differential input signals and 16 additional pairs of screw terminals for current excitation signals.

The National Instruments SCXI-1306 Terminal Block can perform 2-, 3-, and 4-wire resistive measurements of transducers, which includes RTDs and thermistors. Every channel can be configured for voltage or resistive measurements. There are two switches for every channel, which can be utilized to choose the measurement type. In addition, the 16 differential analog channels can be utilized to complete floating and grounded voltage measurements. Thermocouple measurements are characteristic for a floating measurement. For floating or grounded voltage measurements, the user can link the voltage source to the analog input screw terminals. Then, the user can modify the switch positions, based on the type of signal they are measuring. When the user is measuring floating signals, they can link the negative input to the internal ground of the SCXI-1503 RTD Module.

One of the beneficial features of the NI SCXI-1306 Terminal Block is the integrated temperature sensor. This feature can be utilized for thermocouple cold junction compensation. To ensure precise cold-junction compensation, the user must not keep the SCXI chassis near any extreme temperature differential. It is also recommended by NI to average a high quantity of samples for a precise reading.
