這SCXI-1320(零件號:777687-20)高壓接線板用螺絲端子屏蔽，可以連接到幾個模塊的輸入連接器SCXI-1121,SCXI-1120D,SCXI-1126,SCXI-1120，或者SCXI-1125。這SCXI 1320有18個螺絲終端輕松連接。一對螺絲端子可以連接到SCXI模塊底盤接地。當這個接線盒與SCXI-1120/D,SCXI-1125，或者SCXI-1126，則其他八對螺絲端子用于信號連接到八個模塊輸入。然而，當鎳SCXI-1320與SCXI-1121，則四對螺釘端子用于四個模塊輸入，而另外四對用于模塊激勵輸出。

這接線盒還配有片上溫度傳感器，利用熱電偶進行冷結(jié)補償。它由推薦鎳使SCXI機箱遠離極端溫差，以實現(xiàn)精確的冷結(jié)補償。

當準備使用NI SCXI 1320接線板，這些項目是必需的:SCXI機箱、SCXI模塊(SCXI-1120,SCXI-1120D,SCXI-1121,SCXI-1125，或者SCXI-1126)、1號和2號十字螺絲刀、一把鋼絲鉗、一把電線絕緣剝離劑、一把尖嘴鉗和一把1/8英寸。平頭螺絲刀。要附加SCXI 1320要連接SCXI模塊的前連接器，首先將前連接器連接到上的相應連接器SCXI-1320。然后，確保擰緊背面的頂部和底部指旋螺釘接線盒所以它被鎖定在適當?shù)奈恢谩?/font>

The SCXI-1320 (Part Number: 777687-20) High-Voltage Terminal Block is shielded with screw terminals that can connect to several module’s input connector: the SCXI-1121, SCXI-1120D, SCXI-1126, SCXI-1120, or SCXI-1125. The SCXI 1320 has 18 screw terminals for effortless attachment. A pair of screw terminals can attach to the SCXI module chassis ground. When this Terminal Block is used with the SCXI-1120/D, SCXI-1125, or SCXI-1126, then the other eight pairs of screw terminals are used for signal attachment to the eight module inputs. However, when the NI SCXI-1320 is used with the SCXI-1121, then four pairs of screw terminals are meant for the four module inputs, while another four pairs are meant for the module excitation outputs.

This Terminal Block is also equipped with an onboard temperature sensor for cold-junction compensation utilizing thermocouples. It is recommended by NI to keep the SCXI chassis away from an extreme temperature differential for precise cold-junction compensation.

When preparing to use the NI SCXI 1320 Terminal Block, these items are required: an SCXI chassis, an SCXI module (SCXI-1120, SCXI-1120D, SCXI-1121, SCXI-1125, or SCXI-1126), Number 1 and 2 Philips-head screwdrivers, a wire cutter, a wire insulation stripper, long-nose pliers, and a 1/8 in. flathead screwdriver. To attach the SCXI 1320 to the SCXI module’s front connector, first link the front connector to the appropriate connector on the SCXI-1320. Then, make sure to tighten the top and bottom thumbscrews on the back of the Terminal Block so it is locked in place.
