Principle of Operation:
The chassis operates as a USB-based data acquisition front-end, hosting up to four C Series I/O modules. It manages the timing and synchronization of measurements across multiple modules, with multiple timing engines enabling four hardware-timed operations simultaneously at three independent rates for analog input.

Advantages and Strengths:

• Plug-and-play USB connectivity simplifies system setup

• Supports mixed measurement types (analog I/O, digital I/O, counter/timer) through C Series module combinations

• Portable and compact form factor ideal for field measurements

Applicable Industries:
Sensor measurement systems, portable test and measurement, data logging, industrial monitoring.

Model Series: CompactDAQ

Installation Requirements:
Panel mounting required to meet specifications. Use an NI locking USB cable and affix ferrules to the ends of terminal lines.

Usage Precautions:
Specifications are typical at 25 °C unless otherwise noted. C Series I/O module specifications are detailed in the documentation for each specific module.
