cDAQ-9174

The cDAQ‑9174 is a CompactDAQ USB chassis designed for small, portable sensor measurement systems. The chassis provides the plug‑and‑play simplicity of USB to sensor and electrical measurements. It also controls the timing, synchronization, and data transfer between C Series I/O modules and an external host. You can use this chassis with a combination of C Series I/O modules to create a mix of analog I/O, digital I/O, and counter/timer measurements. Additionally, the cDAQ‑9174 features four 32‑bit general-purpose counters/timers. With multiple timing engines, you can run four hardware-timed operations simultaneously, with three independent rates for analog input.

Applications and Use Cases of cDAQ-9174

The cDAQ-9174 USB CompactDAQ Chassis is a 4-slot USB CompactDAQ chassis designed for portable, benchtop, and modular measurement systems. It serves as the core platform for NI C Series modules and manages timing, synchronization, and data transfer between the installed modules and the host PC. It also includes four 32-bit general-purpose counters/timers, making it suitable for a wide range of sensor, electrical, and control applications.

1. Portable and Benchtop Data Acquisition
cDAQ-9174 is widely used in compact test and measurement systems where engineers need a small, USB-based platform for connecting sensors and collecting data in laboratories, workshops, and engineering environments.

2. Sensor Measurement and Monitoring
When combined with compatible C Series modules, it can be used to measure temperature, voltage, current, strain, vibration, pressure, and many other sensor signals, making it suitable for both industrial and research applications.

3. Industrial Monitoring and Machine Diagnostics
cDAQ-9174 is commonly used for equipment monitoring, condition monitoring, and machine diagnostics, especially in applications that require a reliable modular DAQ platform with USB connectivity.

4. Mixed-Signal Test Systems
Because it supports a mix of analog input, analog output, digital I/O, and counter/timer modules, cDAQ-9174 is ideal for mixed-signal test setups used in product validation, functional testing, and system verification.

5. Counter/Timer and Encoder Applications
With its built-in four 32-bit counters/timers, the chassis can support encoder measurement, pulse generation, event counting, and frequency/period measurement when used with the appropriate modules.

6. Education, Research, and Engineering Development
cDAQ-9174 is widely adopted in universities, R&D labs, and engineering departments for prototype development, experiment validation, and modular measurement system design.

7. Small Automation and Control Projects
Its compact size and USB plug-and-play design make it a practical solution for small automation systems, embedded monitoring projects, and low-to-medium channel count control applications.
