Description
The SCXI-1503 is a Temperature Input Module manufactured by National Instruments, bearing the part number 185540G-01 (also known under NI Part Number: 779638-01). This module falls under the SCXI & Legacy category and is designed to offer precise temperature measurement capabilities.
The module features 16 channels, each with a selectable gain of either 1 or 100, allowing for adaptable measurement configurations based on the specific requirements of the application. It incorporates a lowpass filter with a cutoff frequency of 5 Hz, ensuring the mitigation of high-frequency noise in the temperature data.
Each channel on the SCXI-1503 provides a constant current excitation of 100 µA, critical for accurate temperature measurements with resistive sensors. The accuracy of these current sources is maintained within ±0.05% of the nominal value, contributing to the module’s overall precision. Temperature drift is minimized, with a coefficient of ±5 ppm/°C, ensuring reliable performance across varying environmental conditions.
Compatibility with terminal blocks such as the SCXI-1306, SCXI-1310, and TBX-96 is provided, offering flexibility in connecting and configuring the temperature measurement system. Moreover, the module supports NIDAQmx software (version 8.1 or later), facilitating integration with data acquisition and analysis systems.
To maintain its high performance and accuracy, the SCXI-1503 requires calibration, which is recommended annually or every two years, depending on the usage intensity and the precision requirements of specific applications. The module weighs 26.3 oz and has dimensions of 7.4 x 6.8 x 1.2 inches, making it a compact and manageable addition to any data acquisition setup. Lastly, it operates effectively within a temperature range of 0 to
