SCXI-1581

National Instruments NI SCXI-1581 32-Channel Current Excitation Module
Features

• 32 Channels of 100 µA Current Excitation Sources
• Use with SCXI-1102 Module for High-Channel-Count RTD Measurements
• NI-DAQmx Measurement Services Software to Simplify Configuration and Measurements
• 5 ppm/°C Maximum Temperature Drift
• ±0.05% Accuracy for Each Current Source

The National Instruments 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. The module is ideal in any application that requires a 100 µA fixed current excitation, such as resistive temperature devices (RTDs). You can use the SCXI-1581 with the SCXI-1102 to create a high-channel-count RTD measurement system.

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.
