Use the SCXI Advisor to configure an SCXI data acquisition (DAQ)system based on this module.

The National Instruments 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). You can also scan the cold-junction compensation sensor along with other input channels. The SCXI-1102 also can acquire millivolt, volt, 0 to 20 mA, and 4 to 20 mA current input signals. Each module can multiplex its channels into a single DAQ device channel, and you can add modules to increase channel count.

You can use the SCXI-1600USB DAQ device with this module to create a completely plug-and-play USB DAQ system. An SCXI chassis is required to house the SCXI-1600 and assorted SCXI modules for a particular system. The SCXI-1000 chassis holds up to four modules while the SCXI-1001 holds up to 12.

You can use the SCXI-1102 with the SCXI-1581 for RTD measurements.
