Use the "Configure System" link above to configure an SCXI DAQ system based on this module.
The NI SCXI-1121 and SCXI-1122 modules 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 provide 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. In addition, they 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.
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.
