Product Description

The NI cDAQ-9181 is a single-slot, USB-based chassis from National Instruments. It is a key component of the CompactDAQ platform, which is a modular data acquisition system. The cDAQ-9181 acts as the communication bridge and backplane for a single C Series I/O module. Its primary function is to connect a C Series module, such as a voltage or temperature input module, to a computer via a USB cable, allowing for the easy and portable collection of data.

Product Parameters

• Model Name: cDAQ-9181
• Product Type: Single-slot, USB-based chassis
• Module Slots: 1 C Series module slot
• Connectivity: High-speed USB 2.0
• Data Transfer Rate: Up to 1.28 MS/s aggregate for multiple analog input channels
• Power Supply: External power supply (included)
• Operating Temperature: -20 °C to 55 °C (-4 °F to 131 °F)
• Built-in Features: Timing engine, synchronization capabilities for multiple modules, and built-in hot-swapping.
• Compatibility: Compatible with all NI C Series modules.
• Software Support: NI-DAQmx, LabVIEW, LabWindows/CVI, and other software platforms.

Product Advantages

• Portability and Ease of Use: The cDAQ-9181’s small, single-slot design and USB connectivity make it extremely portable and easy to set up. It’s perfect for quick, on-site measurements and benchtop data acquisition.
• Modular and Flexible: It supports a wide range of C Series modules, so you can easily swap modules to measure different types of signals—from voltage and temperature to current and strain—without needing to purchase a new chassis.
• High-Speed Performance: Despite its small size, the cDAQ-9181 provides a high-speed data transfer rate, making it suitable for a variety of applications that require fast and accurate measurements.
• Rugged Design: The chassis is built to withstand industrial environments with a wide operating temperature range and robust construction.
• Synchronized Timing: The chassis’s built-in timing engine allows for the synchronization of multiple modules when used with other cDAQ chassis, which is essential for complex measurements.

Precautions

• Single-Slot Limitation: The cDAQ-9181 only supports one C Series module. If your application requires more than one module, you would need to use a multi-slot chassis (e.g., cDAQ-917x series) or multiple single-slot chassis.
• Proper Power Supply: Ensure you use the provided external power supply. While some C Series modules can be powered over USB, others require the external supply for proper operation.
• Software Installation: The correct NI-DAQmx drivers must be installed on your computer before you can use the chassis and C Series modules.
• ESD Protection: Always follow proper electrostatic discharge (ESD) precautions when handling the chassis and modules to prevent damage to the electronics.

Product Applications

The NI cDAQ-9181 is an ideal solution for a variety of portable and benchtop data acquisition applications. Its uses include:

• Field Testing: On-site data collection for troubleshooting, system validation, or environmental monitoring.
• Academic and Laboratory Research: Quick, flexible measurements in a lab environment for scientific experiments.
• Automated Test and Measurement: As a single-channel component in automated test benches for a variety of products.
• Process Monitoring: Collecting data from sensors in a small-scale industrial process for analysis and control.
