The NI SCXI-1102 and SCXI-1112 are designed for high-accuracy thermocouple measurements. They share a common architecture where each input channel includes an instrumentation amplifier and a 2 Hz lowpass filter. With this architecture, you can scan the NI SCXI-1102 or SCXI-1112 analog input channels along with the input channels of other modules at rates up to 333 kS/s (3 µs per channel). In addition, you can scan the cold-junction compensation sensor along with other input channels. The SCXI-1102 can also acquire millivolt, volt, 0 to 20 mA, and 4 to 20 mA current input signals. Each module can multiplex its channels into a single channel of the DAQ device, and you can add modules to increase channel count.
An SCXI chassis is required to house the SCXI modules. The NI SCXI-1000 chassis can hold up to four modules while the NI SCXI-1001 can hold up to 12. You can choose NI X Series, M Series, E Series, or S Series DAQ modules for controlling the chassis.

Extended Warranties
National Instruments designs and manufactures all products to minimize failures, however unexpected failures can still occur. Extended warranties provide a fixed economical price at the time of system purchase, covering any repair costs for up to three years. In addition, they offer the following benefits:
Significant cost savings compared to individual repair incidents
Fault location, diagnostics, and repair by NI any time the system product fails
All parts and labor costs covered as well as any adjustments needed to restore the hardware to manufacturing specifications
NI recognizes the need to maintain properly calibrated devices for high-accuracy measurements. NI provides manual calibration procedures, services to recalibrate your products, and automated calibration software to calibrate many NI measurement products.
Return your registered product under warranty at no additional labor and parts cost. NI offers fault location, diagnostics, and repair any time the system fails as well as any adjustments needed to restore the hardware to manufacturing specifications.
