這SCXI-1315(零件號:777687-15)是一個前置安裝接線盒為配合使用而創(chuàng)建SCXI-1540 LVDT模塊。這種組合可以通過螺釘端子簡單連接到線性可變差動變壓器(LVDTs)、旋轉(zhuǎn)可變差動變壓器(RVDTs)和旋變器。這SCXI 1315具有26 10 14 AWG最大現(xiàn)場線規(guī)。這NI SCXI-1315接線板有48個螺絲端子，分為八組，每組六個。每組端子對應(yīng)于上總共八個通道中的一個通道SCXI-1540。

這個8頻道接線盒每個LVDT通道有六個端子，如下所示:CH+、CH-、EX+、EX-、SYNC和GND。首先，CH+(N)是來自LVDT次級的輸入信號，是正端。其次，CH-(n)是負(fù)端，是來自LVDT次級的輸入信號。EX+(n)指LVDT初級線圈的激勵信號；這是一個正極端子。接下來，EX-(n)指的是LVDT初級線圈的激勵信號，但它是一個負(fù)端。SYNC(n)是輸入同步信號。最后，GND提到地面。

當(dāng)用戶設(shè)置他們的國家儀器公司SCXI-1315 LVDT接線板中，有幾項要求使設(shè)置盡可能簡單。用戶將需要安裝指南、SCXI機箱SCXI-1540 LVDT模塊和用戶手冊，一個電線絕緣剝線鉗，一個鋼絲鉗，尖嘴鉗，一個1/8英寸。平頭螺絲刀，1號和2號十字螺絲刀。

The SCXI-1315 (Part Number: 777687-15) is a Front-Mounting Terminal Block created for utilization with the SCXI-1540 LVDT module. This combination enables simple connection to linear variable differential transformers (LVDTs), rotary variable differential transformers (RVDTs), and resolvers via screw terminals. The SCXI 1315 has 26 10 14 AWG maximum field wire gauge. The NI SCXI-1315 Terminal Block has 48 screw terminals, which are organized in eight groups of six. Every group of terminals corresponds to a single channel of the eight total channels on the SCXI-1540.

This 8-Channel Terminal Block has six terminals for every LVDT channel, which are as follows: CH+, CH-, EX+, EX-, SYNC, and GND. First, CH+(N) is the input signal from the LVDT secondary and is a positive terminal. Secondly, CH-(n) is a negative terminal and is an input signal from the LVDT secondary. EX+(n) refers to the excitation signal to the LVDT primary; it is a positive terminal.  Next, EX-(n) refers to the excitation signal to the LVDT primary but is a negative terminal. SYNC(n) is an input synchronization signal. Lastly, GND refers to ground.

When the user is setting up their National Instruments SCXI-1315 LVDT Terminal Block, there are a few items required to make the setup as simple as possible. The user will need the Installation Guide, an SCXI chassis, the SCXI-1540 LVDT Module and User Manual, a wire insulation stripper, a wire cutter, long-nose pliers, a 1/8 in. flathead screwdriver, and Number 1 and 2 Philips-head screwdrivers.
