這倪SCXI 1328(零件號:777687-28)有18個螺絲端子連接到SCXI-1120,SCXI-1120D,SCXI-1121,SCXI-1125，以及SCXI-1126模塊。在18個螺絲端子中，只有一對連接到SCXI底盤接地。為了SCXI-1120/D,SCXI-1125，以及SCXI-1126其他八對螺絲端子用于信號連接到八個模塊輸入。但是，對于SCXI-1121四對螺絲端子用于四個模塊輸入，四對用于模塊激勵通道。這SCXI-1328最大現(xiàn)場線規(guī)為26至14 AWG。這鎳SCXI-1328具有DC耦合，在15至35攝氏度時精度為0.5攝氏度，在0至15攝氏度和35至55攝氏度時精度為0.9攝氏度

這SCXI 1328屏蔽接線盒配有用于精確冷結(jié)補(bǔ)償?shù)母呔葻崦綦娮?，以及一個鋁制等溫板，當(dāng)用戶用熱電偶完成測量時，可降低螺釘端子上的溫度梯度。這倪SCXI 1328具有板載溫度傳感器，可測量內(nèi)部的環(huán)境溫度接線盒。如果用戶使用熱電偶測量溫度，則可以從片上溫度傳感器獲取溫度，用于冷結(jié)補(bǔ)償。要將電壓讀數(shù)轉(zhuǎn)換為溫度，用戶可以利用熱敏電阻轉(zhuǎn)換公式。如果用戶運(yùn)行LabVIEW，他們可以使用轉(zhuǎn)換熱敏電阻VI。如果用戶正在運(yùn)行NI-DAQ，他們可以使用熱敏電阻_Convert函數(shù)調(diào)用。

The NI SCXI 1328 (Part Number: 777687-28) has 18 screw terminals to connect to the SCXI-1120, SCXI-1120D, SCXI-1121, SCXI-1125, and SCXI-1126 modules. Of the 18 screw terminals, a single pair attaches to the SCXI chassis ground. For the SCXI-1120/D, SCXI-1125, and SCXI-1126, the other eight pairs of screw terminals are utilized for signal connection to the eight module inputs. However, for the SCXI-1121, four pairs of screw terminals are used for the four module inputs and four pairs are used for the module excitation channels. The SCXI-1328 has a maximum field wire gauge of 26 to 14 AWG. The NI SCXI-1328 has DC coupling, 0.5 °C accuracy at 15 to 35 ?C, and 0.9 °C at 0 to 15 ?C and 35 to 55 ?C.

The SCXI 1328 Shielded Terminal Block comes equipped with a high-precision thermistor for accurate cold-junction compensation, along with an aluminum isothermal plate to reduce the temperature gradients across the screw terminals when the user completes measurements with thermocouples. The NI SCXI 1328 has an onboard temperature sensor, which measures ambient temperature on the interior of the Terminal Block. If the user is measuring temperatures with thermocouples, then they can acquire a temperature from the onboard temperature sensor which can be utilized for cold-junction compensation. To change the voltage reading to a temperature, the user can utilize a thermistor conversion equation. If the user is running LabVIEW, they can use the Convert Thermistor VI. If the user is running NI-DAQ, they can use the Thermistor_Convert function call.
