Expert Insights for the cDAQ-9171
"The cDAQ-9171 is a portable CompactDAQ chassis that supports a single NI module. It is an excellent choice for low powered, simple sensors. Its plug and play functionality supports timing, synchronization, and data transfers between C Series I/O modules and the host. The all metal design provides an industrial feel, yet it is simple to set up."

National Instruments cDAQ-9171 CompactDAQ Chassis
The cDAQ-9171 (Part Number: 781425-01) is a bus-powered CompactDAQ chassis intended for small and convenient sensor measurement systems. Manufactured by NI (the test and measurement division of Emerson), the instrument gives the simplicity of a high-speed USB connection (plug-and-play) to its electrical and sensor measurements. This CompactDAQ also controls timing, synchronization, and data transfer between the C Series I/O modules and an external power supply. The user can utilize this chassis with a blend of C Series I/O modules to perform different measurements of analog I/O, digital I/O, and counter/clock. The cDAQ-9171 has four 32-bit general purpose clocks/counters that can be reached through an hardware-timed C Series computerized module in applications that utilize quadrature encoders, pulse width estimations, event counting, pulse train generation, and period or frequency measurements. The cDAQ framework is comprised of three parts: C Series module(s), the STC3, and the cDAQ module interface. These parts digitize signals, perform D/A (digital-to-analog) conversions to create analog output signals, measure and control computerized I/O signals, and offer signal conditioning. The device has a USB 2.0 high-speed bus connector and has a timing resolution of 12.5 ns.
The NI cDAQ-9171 USB Chassis supports sensor-specific I/O modules with integrated signal conditioning. This USB chassis allows the user to run as many as six hardware-timed analog I/O, digital I/O, or counter/timer operations at the same time. The number of channels the cDAQ-9171 can support, the sample rate, and several other specifications are based on the C Series module used with the chassis. The device has the capability to be mounted to a panel or a wall. The optional mounting kits can be purchased separately. When mounted, the chassis should not be stacked. This model is run using the NI-DAQmx driver software, which is compatible with software packages like LabVIEW, LabWindows/CVI, or Measurement Studio.
The NI device weighs 12.5 oz and measures 5.17 x 3.49 x 1.31 in. in physical dimensions. It has a power consumption of 500 mA maximum at 5 V, a recommended operating temperature range of -20 °C to 55 °C, and a storage temperature range of -40 °C to 85 °C. Additional specifications for the cDAQ-9171 can be found in the manuals and datasheets under the "Manuals & PDFs" tab.
