SCXI-1600

• “SCXI”: NI’s legacy identifier for “Signal Conditioning eXtensions for Instrumentation,” retained for compatibility with cDAQ systems (originally from NI’s SCXI chassis product line).
• “1600”: Specifies core functionality—”1″ denotes analog input, “6” indicates high-precision (16-bit resolution), and “00” marks the base configuration (no built-in signal conditioning for general-purpose use).

2. Product Description

e engineered by National Instruments for high-accuracy sensor signal acquisition in cDAQ-based measurement systems (e.g., laboratory R&D, manufacturing quality control, environmental monitoring). As a plug-in module for NI’s CompactDAQ chassis (e.g., cDAQ-9178, cDAQ-9179), its primary function is to convert analog signals from sensors (e.g., pressure transmitters, thermocouples, strain gauges) into digital data, which is then transmitted to a host PC or embedded controller via USB/Ethernet for analysis.

1. High-Resolution Acquisition: Features 16-bit ADC resolution and 100 kS/s (kilo-samples per second) aggregate sampling rate, enabling accurate capture of low-level sensor signals (e.g., 1mV strain gauge outputs) with minimal noise—critical for applications like material stress testing.
2. Versatile Signal Compatibility: Supports multiple analog input types, including differential voltage (±10V), single-ended voltage (0–10V), and current (4–20mA via external shunts), eliminating the need for dedicated modules for mixed sensor fleets.
