The NI cDAQ-9174 is a 4-slot NI CompactDAQ USB chassis designed for small, portable, mixed-measurement test systems. Combine the cDAQ-9174 with up to four NI C Series I/O modules for a custom analog input, analog output, digital I/O, and counter/timer measurement system.

Modules are available for a variety of sensor measurements including thermocouples, RTDs, strain gages, load and pressure transducers, torque cells, accelerometers, flow meters, and microphones. NI CompactDAQ systems combine sensor measurements with voltage, current, and digital signals to create custom, mixed-measurement systems with a single, simple USB cable back to the PC, laptop, or netbook.

The cDAQ-9174 has four 32-bit general-purpose counter/timers built in. You can access these counters through an installed, hardware-timed digital NI C Series module such as the NI 9401 or NI 9402 for applications that involve quadrature encoders, PWM, event counting, pulse train generation, and period or frequency measurement.

The cDAQ-9174 chassis is shipped with the following:
- AC/DC converter that plugs directly into the chassis
- USB cable with a thumbscrew lock for strain relief

Power cord sold separately.

For conditions where EMI could be an issue, you can use the 7.0 mm EMI suppression ferrites to suppress EMI for BNC cabling to the chassis.

NI-DAQmx driver software is shipped with every chassis and includes the following:

- LabVIEW SignalExpress LE for simple data-logging applications
- API for LabVIEW, ANSI C/C++, C#, and Visual Basic .NET
- DAQ Assistant code generation for NI LabVIEW, LabWindows™/CVI, and Measurement Studio
- Example programs for all supported languages
- NI Measurement & Automation Explorer (MAX) for system configuration and test
