這國家儀器公司SCXI-1100(零件號:776572-00)是一個32通道SCXI的電壓輸入模塊。該模塊專為毫伏、伏特和電流信號的經(jīng)濟實惠的信號調理而設計。所有通道都是多路復用的，帶有跳線可選的4 Hz低通濾波器，可選擇多個增益范圍。這些通道被多路復用到控制DAQ儀器的一個通道中。結果是DAQ系統(tǒng)有更多的頻道。一個額外的屏蔽接線板有螺絲端子，用于簡單的信號連接SCXI 1100模塊。此外，端子板上還包括一個用于熱電偶冷結補償?shù)臏囟葌鞲衅?。冷結基準電壓源可以與上的32個通道多路復用鎳SCXI-1100。另一種選擇是將冷結基準電壓源跳線連接到數(shù)據(jù)采集板的不同通道。

這鎳SCXI-1100模塊可以與NI MIO板一起使用，包括PC-LPM-16、Lab-LC、Lab-PC+、Lab-PC和Lab-NB。然而，這些板只能完成單通道讀?。凰麄儾荒軖呙枘K。

這SCXI-1100 電壓輸入模塊可用于各種接線盒，包括機架安裝、熱電偶插頭、螺絲端子、BNC連接器、DIN導軌安裝、焊接引腳和前置安裝接線盒。這SCXI 1100可與以下產品一起使用美國國家儀器公司端子板:SCXI-1300、SCXI-1303、SCXI-1308、BNC-2095、TC-2095、TBX-1303、TBX-96和SCXI-1310。其中一些端子板具有額外的功能。例如，SCXI-1310的一個特點是價格合理的連接器和外殼組件。此外，BNC-2095已經(jīng)預連線地面參考。TC-2095具有等溫結構和可切換地面參考。此外，SCXI-1303具有可插拔接地參考。

The National Instruments SCXI-1100 (Part Number: 776572-00) is a 32-Channel Voltage Input Module for SCXI. This module is created for affordable signal conditioning of millivolt, volt, and current signals. All channels are multiplexed with the option of several gain ranges with a jumper-selectable 4 Hz lowpass filter. The channels are multiplexed into one channel of a controlling DAQ instrument. The outcome is a higher number of channels for the DAQ system. An additional shielded terminal block has screw terminals for simple signal attachment to the SCXI 1100 module. Additionally, a temperature sensor for cold-junction compensation of thermocouples is included on the terminal block. The cold-junction reference can be multiplexed with the 32 channels on the NI SCXI-1100. The other option is for the cold-junction reference to be jumper connected to a different channel of the data acquisition board.

The NI SCXI-1100 module can be utilized with the NI MIO boards, including the PC-LPM-16, Lab-LC, Lab-PC+, Lab-PC, and Lab-NB. However, these boards can solely accomplish one-channel reads; they cannot scan the module.

The SCXI-1100 Voltage Input Module can be used with a variety of terminal blocks, including rack-mounted, thermocouple plugs, screw terminals, BNC connectors, DIN-rail mount, solder pins, and front-mounting terminal blocks. The SCXI 1100 can be used with the following National Instruments Terminal Blocks
