Use SCXI Advisor to configure an SCXI data acquisition system based on this module.
National Instruments SCXI-1121 and SCXI-1122 are designed for a wide variety of sensor and signal inputs requiring isolation. The SCXI-1121 offers independently configurable isolation amplifiers, filters, and excitation sources for each channel. Both modules offer 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. Both modules can multiplex their channels into a single channel of the DAQ device, and you can add modules to increase channel count. The SCXI-1121 also offers parallel-mode operation.
