Product Description

The NI cDAQ-9181 is a single-slot, network-enabled chassis that forms the core of a modular data acquisition (DAQ) system. It is designed to host one NI C Series I/O module, transforming it into a high-performance, compact, and portable measurement device.

It communicates with a host computer (PC, laptop, or controller) over standard Gigabit Ethernet, making it ideal for distributed and remote monitoring applications where the measurement device needs to be located far from the host controller. It handles the timing, synchronization, and communication between the host and the installed C Series module.

Product Parameters

Product Advantages

• Network Capability: Uses standard Ethernet for communication, allowing for distributed, remote measurements over long distances without signal degradation.

• Modularity: Compatible with over 100 different NI C Series I/O Modules (analog input, analog output, digital I/O, counter/timer) to customize the system for specific sensor and measurement requirements.

• Simplified Synchronization: Supports IEEE 1588 Precision Time Protocol (PTP) for tight synchronization (sub-microsecond) between multiple cDAQ chassis over the network.

• Rugged and Portable: Features a robust industrial design and a compact form factor, making it suitable for field testing and harsh industrial environments.

• Ease of Use: Seamless integration with NI software like LabVIEW and the NI-DAQmx driver, simplifying configuration and programming.

Precautions

• NI-DAQmx Driver: The cDAQ-9181 requires the NI-DAQmx driver software to be installed on the host computer for configuration and operation.

• Network Configuration: Proper network setup is crucial. Ensure correct IP addressing and firewall settings to allow communication between the chassis and the host.

• Power Supply: Use a compliant 9 VDC to 30 VDC power supply capable of providing sufficient current for the chassis and the installed C Series module.

• Environmental Limits: While rugged, always operate the chassis within its specified temperature and humidity range to ensure reliability.

Product Applications

The cDAQ-9181 is ideal for applications requiring high-performance, small-channel-count, and distributed data acquisition.

• Field Testing and Validation: Performing measurements on-site in automotive, aerospace, or heavy machinery industries.

• Small Channel Count Monitoring: Permanent monitoring of specific parameters (e.g., temperature, strain, or voltage) in critical industrial assets.

• Remote DAQ: Deploying measurement nodes in locations that are physically distant or electrically noisy from the host control system.

• Research and Education: Providing a flexible, high-accuracy platform for laboratory experiments and academic research.
