Use the "Configure System" link above to configure an SCXI data acquisition (DAQ) system based on this module.
The NI SCXI-1581 provides 32 channels of 100 µA current excitation. The high accuracy and stability of these current sources make them especially well-suited for measuring resistance with a high degree of accuracy. This module is ideal in any application that requires 100 µA fixed-current excitation, such as resistive temperature devices (RTDs). You can use the SCXI-1581 with the NI SCXI-1102 thermocouple/voltage input module to create a high-channel-count RTD measurement system.
The NI SCXI-1600 USB DAQ module can be used 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 NI SCXI-1000 chassis is capable of holding up to four modules while the NI SCXI-1001 can hold up to 12. The SCXI-1600 module can be used only with 32-bit OSs. For 64-bit systems, you can use NI X Series, M Series, E Series, or S Series DAQ modules for control.
