Description
The NI SCXI-1121 Universal Input Module, with part number 776572-21, is a versatile 4-channel module designed to handle a variety of input signal types, including strain, RTD, thermocouple, millivolt, volt, and current signals. It offers an output range of ±5 V and features two distinct output modes: Parallel-Output Mode and Multiplexed-Output Mode, to accommodate different data acquisition strategies.
Compatibility is broad, encompassing NI MIO-16 Boards and several others, such as Lab-PC+, albeit with certain limitations. This module facilitates manual calibration through offset potentiometers, which is recommended to be performed annually to maintain accuracy.
Powered by NIDAQmx driver software, the SCXI-1121 can be programmed using renowned application development environments like LabVIEW and LabWindows/CVI. Its physical footprint measures 1.2 x 6.8 x 7.4 inches and it weighs 23.5 oz. Despite its obsolete status announced by National Instruments, the module remains available for purchase and service through Apex Waves.
