The National Instruments cDAQ-9171 (Part Number: 781425-01) is a compact, powered DAQ chassis designed to support small, portable sensor measurement systems. This instrument provides easy connectivity via USB (plug-and-play) for electrical and sensor measurements.

• Controls planning, synchronization, and data exchange between C Series I/O modules and external systems
• Combination of chassis and C Series I/O modules supports various analog I/O, digital I/O, and counter/timer measurements
• Includes four 32-bit general-purpose counters/timers accessible through application software
• Supports quadrature encoder, pulse width measurement, event counting, pulse train generation, and period/frequency measurement
• Three-component architecture: C Series modules, STC3, and cDAQ module interface
• Performs signal digitization, D/A conversion for analog output signals, and digital I/O signal measurement/control
• USB 2.0 high-speed bus connection with 12.5 ns timing resolution

• Supports over 60 sensor-specific I/O modules with integrated signal conditioning
• Allows simultaneous operation of up to six hardware-timed analog I/O, digital I/O, or counter/timer operations
• Channel count, sampling rate, and other specifications depend on the C Series modules used with the chassis
• Supports panel, wall, or DIN rail mounting (rack mount kit available separately)
• Chassis should not be stacked during installation
• Compatible with NI-DAQmx driver software and LabVIEW, LabWindows/CVI, or Measurement Studio packages
