National Instruments SCXI-1120D Voltage Input Module

The NI SCXI-1120D (Part Number: 776572-20D) 8-Channel Voltage Input Module is created for economical signal conditioning of thermocouple, current, volt, and millivolt sources that need a 20 kHz bandwidth and where high common-mode voltages occur. Every channel has a configurable lowpass filter of 4.5 kHz or 22.5 kHz. This Voltage Input Module can be utilized with complete functionality with the MIO, 1200 Series, and Lab PC+ devices by National Instruments. The SCXI 1120D can additionally be used with the Lab-NB, Lab-LC, Lab-PC, and PC-LPM-16/PnP devices. However, none of these devices can scan the module when it is configured in the multiplexed-output mode. If the SCXI-1120D is used with a shielded terminal block, then the screw terminals added ensure simple signal attachment to the module.

Another useful way to utilize the NI SCXI-1120D is as a swift scanning signal conditioner for applications such as production testing, laboratory testing, and industrial process monitoring. Every input channel on the SCXI-1120D has two gain stages that are user-configurable. The first gain stage delivers gains of 1, 5, 10, 50, and 100. On the other hand, the second gain stage delivers gains of 1, 2, 5, 10, and 20. Also, the NI SCXI-1120D has a fixed pre-stage gain of 0.5.

A few options are available when programming the National Instruments SCXI 1120D Voltage Input Module. The user can utilize VirtualBench, ComponentWorks, LabWindows/CVI, Measure, NI-DAQ, or register-level programming. The use of VirtualBench, ComponentWorks, LabWindows/CVI, or LabVIEW will significantly decrease the time the user spends developing their data acquisition and control application.

SCXI-1120D Obsolete Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves.
