Use SCXI Advisor to configure an SCXI data acquisition system based on this module.

The National Instruments SCXI-1122 is designed for a wide variety of sensor and signal inputs requiring isolation. It offers a single isolation amplifier, filter, and excitation source for all channels. The NI SCXI-1122 offers 250 Vrms working isolation and can acquire strain, RTD, thermocouple, millivolt, volt, 250 V, 0 to 20 mA, and 4 to 20 mA current input signals. It can also multiplex its channels into a single channel of the DAQ device, and you can add modules to increase channel count.

The SCXI-1600 USB data acquisition module can be used in conjunction with this module to create a completely plug-and-play USB data acquisition system. An SCXI chassis is required to house the SCXI-1600 and assorted SCXI modules for a particular system. The SCXI-1000 chassis is capable of holding up to four modules while the SCXI-1001 can hold up to 12.
