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.
