194411C-01

Description

The National Instruments SCXI-1503 Temperature Input Module carries the part number 194411C-01, which is also recognized as 779638-01. This module falls under the SCXI & Legacy category and is identified by the model SCXI-1503. It is designed to accommodate 16 channels, each equipped with an amplifier and a selectable gain of either 1 or 100, making it highly versatile for various temperature sensing applications.

The module features a 5 Hz lowpass filter to ensure clean signal processing. It boasts compatibility with SCXI-1306, SCXI-1310, TBX-96 Terminal Blocks, offering flexibility in system configuration. Each of the 16 channels provides a current excitation of 100 µA, ensuring accurate temperature measurements. The accuracy of these current sources is impressive, at ±0.05% with a temperature drift of just ±5 ppm/°C, guaranteeing reliable readings under varying conditions.

For software interfacing, the SCXI-1503 is supported by NIDAQmx (version 8.1 or later), and is compatible with LabVIEW, LabWindows/CVI, and Measurement Studio, providing a wide range of development environments for application programming. It is recommended that the module undergoes external calibration at least once a year to maintain its accuracy over time.

The physical attributes of the SCXI-1503 include a weight of 26.3 oz and dimensions of 7.4 x 6.8 x 1.2 inches, making it a compact and manageable addition to any setup requiring precise temperature measurements.
