16-Channel Temperature Input Module for SCXI—The SCXI-1503 is a RTD input module with one cold-junction sensor channel. It is ideally suited for measuring resistive transducers such as RTDs or thermistors. The SCXI-1503 can programmatically connect each input to ground, which greatly improves its accuracy by enabling a self-calibration of each input to reduce offset drift errors. You can multiplex several SCXI-1503 modules and other SCXI modules into a single channel on a connected, compatible data acquisition device, which greatly increases the number of analog input signals that you can digitize.
