這SCXI 1331(零件號:777687-31)接線盒安裝到的前面SCXI-1127或者SCXI-1128多路復用器/矩陣開關模塊，提供64個螺絲端子用于連接。這SCXI-1331是利用時的最佳選擇SCXI-1127或者SCXI-1128掃描電壓信號的熱電偶，或者當用戶需要8列x 4行之外的矩陣配置時。這SCXI 1331可以配置SCXI-1127/112864 x 1，1線矩陣、32 x 1，2線矩陣或16 x 1，4線矩陣形式的開關模塊。這通用接線板設計用于信號調理和冷結補償。這鎳SCXI-1331建議用于多路復用器或定制矩陣應用。

上的64個螺絲端子NI SCXI 1331接線板使用戶能夠訪問矩陣。這接線盒另外還有外部觸發(fā)信號端子。當用戶準備好將信號連接到SCXI-1331他們必須首先通過剝去絕緣層(離線端不超過7 mm)來準備信號線。然后，取下頂蓋螺絲，取下頂蓋。然后，用戶可以松開應力消除條上的兩個應力消除螺釘，并將信號線穿過應力消除開口。接下來，將電線的剝皮端完全放入端子中，并通過擰緊端子的螺釘來固定電線。然后，用戶可以將安全接地連接到安全接地片，并擰緊應力消除組件上的兩個螺釘，以確保電纜安全。最后，重新安裝頂蓋，并裝回頂蓋螺絲。

The SCXI 1331 (Part Number: 777687-31) Terminal Block mounts to the front of an SCXI-1127 or SCXI-1128 Multiplexer/Matrix Switch Module, providing 64 screw terminals for connections. The SCXI-1331 is the best choice when utilizing the SCXI-1127 or SCXI-1128 to scan thermocouple of voltage signals or when the user requires a matrix configuration besides 8 columns x 4 rows. The SCXI 1331 can configure the SCXI-1127/1128 Switch Module as a 64 x 1, 1-wire matrix, a 32 x 1, 2-wire matrix, or a 16 x 1, 4-wire matrix. This General-Purpose Terminal Block is designed for signal conditioning and cold-junction compensation. The NI SCXI-1331 is suggested for multiplexer or customized matrix applications.

The 64 screw terminals on the NI SCXI 1331 Terminal Block enable the user to access the matrices. The Terminal Block additionally has terminals for external trigger signals. When the user is ready to connect signals to the SCXI-1331, they must first prepare the signal wire by stripping the insulation (no more than 7 mm from the end of the wire). Then, take the top cover screw off and take off the top cover. The user can then loosen the two strain-relief screws on the strain-relief bar and run the signal wires through the strain-relief opening. Next, put the stripped end of the wire completely into the terminal and secure the wire by tightening the screw of the terminal. The user can then link the safety earth ground to the safety ground lug and tighten the two screws on the strain-relief assembly to make sure the cables are secure. Lastly, reinstall the top cover and put the top cover screw back.
