The National Instruments SCXI-1120D is an 8-channel voltage input module designed for efficient and economical signal conditioning of thermocouples, currents, voltages, and millivolt sources, specifically where high common-mode voltages are present. This module features a bandwidth of up to 20 kHz and offers configurable low-pass filtering options of either 4.5 kHz or 22.5 kHz. It integrates seamlessly with National Instruments’ MIO, 1200 Series, and Lab PC+ devices, as well as with Lab-NB, Lab-LC, Lab-PC, and PC-LPM-16/PnP devices, although it is important to note that multiplexed-output configuration prevents scanning by these devices. The SCXI-1120D is optimized for rapid signal conditioning applications, including production testing, laboratory experimentation, and industrial process monitoring. Each input channel is equipped with two user-configurable gain stages, providing various gain settings: the first stage supports gains of 1, 5, 10, 50, and 100, while the second stage offers gains of 1, 2, 5, 10, and 20, alongside a fixed pre-stage gain of 0.5. For user convenience, multiple programming options are available, which include VirtualBench, ComponentWorks, LabWindows/CVI, Measure, NI-DAQ, or register-level programming, significantly enhancing development efficiency when creating data acquisition and control applications. Although the SCXI-1120D has reached obsolete status, it remains available for purchase and repair through Apex Waves. For connection, the module is fitted with a 50-pin male ribbon cable back connector and a 32-pin male DIN C front connector, and it is compatible with shielded terminal blocks for simplified signal attachment. The unit dimensions are 12.2 by 6.8 by 8.0 inches, and it is covered by a warranty of 2 to 3 years. Comprehensive user and maintenance manuals are available for download.
