Data Sheet

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

The National Instruments SCXI-1521 is a 24-channel 350 Ω strain gage input module that offers all of the features you need for quarter-bridge strain measurements. The NI SCXI-1521 offers a fixed-gain amplifier and fixed 2-pole Butterworth filter on each channel to ensure accurate measurements. Each channel also has an independent 0 to 5 V programmable excitation source with 1023 steps of resolution. In addition, the SCXI-1521 offers an internal 100 kΩ shunt calibration resistor on each channel for gain calibration. The SCXI-1521 module is used in conjunction with the SCXI-1317 terminal block, which offers screw terminal connections.

The SCXI-1600USB 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.
