National Instruments SCXI-1102 Voltage Input Module

The NI SCXI-1102 (Part Number: 776572-02, 183087H-01) is a 32-Channel Voltage Input Module that can complete hardware scanning of cold-junction sensors. This module has 2 Hz lowpass filtering for each channel. This module has overvoltage protection to ±42 V, 2 Hz bandwidth, and 333 kS/s maximum sampling rate. Since this module has a 2 Hz bandwidth, after altering the gains, the user must wait about 3 seconds to obtain a precise measurement. The SCXI-1102 Voltage Input Module is ideal for high-accuracy thermocouple measurements. This module can obtain millivolt, volt, 0 to 20 mA, and 4 to 0 mA current input signals. The NI SCXI-1102 module can obtain signals from RTDs as well when the SCXI-1581 delivers excitation.

The SCXI 1102 can be used with the SCXI-1300, SCXI-1303, SCXI-1308, SCXI-1310, TC-2095, TBX-1303, or TBX-96 terminal block. An isothermal terminal block such as the SCXI-1303 is suggested for precise thermocouple measurements. Other items required to operate the NI SCIXI 1102 Voltage Input Module include: an SCXI chassis or PXI/SCXI combination chassis, the SCXI-1600 or E/M Series DAQ Device, a computer (if using an SCXI chassis), cabling, cable adapter, and sensors as needed for the user’s application. Applications can be developed on the device using the NI-DAQmx driver software and other application development environments (ADEs) like LabVIEW, LabWindows/CVI, or Measurement Studio.

The back signal connector on the cabled module is the interface between the DAQ device and the modules in the SCXI chassis. CH 0 is employed to differentially multiplex the 32 channels, the CJ sensor, and analog signals from the modules to the linked DAQ device. If the SCXI-1102 module has a DAQ device linked to it, then the digital lines are not available for general-purpose digital I/O. The NI device is equipped with a 96-pin male DIN C front connector and a 50-pin male ribbon cable rear connector. The DC coupled device weighs 24.6 oz., and measures 1.2 x 6.8 x 8.0 in. in physical dimensions. It has a recommended operating temperature range of 0 to 50 °C.

SCXI-1102 Obsolete Status has been announced by National Instruments, but the module will still be available for purchase and repairs by Apex Waves. 

The SCXI-1102 is available to be calibrated. While the recommended calibration period for individual parts varies, most parts should be calibrated either annually or every two years to ensure accuracy. If you need the SCXI-1102 calibrated, Apex Waves provides options. We offer high-quality NIST accredited calibrations through a 3rd party, with an average turnaround time of 1 to 2 weeks. When you order the SCXI-1102 with us, you can request basic (unaccredited) in-house calibration that will calibrate the part to the manufacturer specifications prior to being shipped.
