NI SCXI-1180

Product Introduction

The National Instruments SCXI – 1180 is a unique and valuable component within the SCXI (Signal Conditioning eXtension for Instrumentation) product family. It is not a traditional module but rather a feed – through panel. Its primary function is to enable the seamless integration of unconditioned signals into a rugged and compact SCXI chassis – based system.

Equipped with a front panel and a 50 – pin ribbon – cable assembly, the SCXI – 1180 serves as a crucial link between the external unconditioned signals and the SCXI system. It allows users to access the unused channels and counters of the data acquisition (DAQ) device that is connected to the SCXI chassis. This means that in complex data acquisition and control systems, the SCXI – 1180 provides an additional layer of flexibility, ensuring that all available resources of the DAQ device can be fully utilized.

Functionally, it occupies only one slot in the SCXI chassis. This space – efficient design enables it to be easily incorporated into existing SCXI setups without taking up excessive space. The 50 – pin ribbon – cable assembly is used to connect various components such as analog sensors, signal generators, and signal conditioning modules. This connection mechanism simplifies the wiring process, reducing the complexity of setting up a data acquisition or control system.

Core Advantages and Technical Highlights

Easy Wiring and Connection

The design of the SCXI – 1180’s feed – through panel significantly simplifies the wiring of analog signals. By providing a clear and organized way to connect different components, it reduces the likelihood of connection errors. In a multi – channel data acquisition system, for example, where numerous sensors and signal sources need to be connected, the SCXI – 1180’s straightforward wiring design ensures that the process is efficient and accurate. This not only saves time during the system setup but also improves the overall signal stability and reliability, as proper connections are essential for minimizing signal interference and distortion.

Versatile Compatibility

The SCXI – 1180 is highly compatible with a wide range of data acquisition boards and software platforms. It can work with PC, AT, and MC boards, using NI – DAQ software for DOS / Windows / Lab Windows. Additionally, it is suitable for NB series data acquisition boards, operating with LabVIEW or NI – DAQ software for Macintosh. This compatibility makes it a versatile choice for different types of users, whether they are using a Windows – based PC for industrial control applications or a Macintosh for research – related data acquisition. It also means that the SCXI – 1180 can be integrated into existing systems with different hardware and software configurations, providing a seamless upgrade or expansion option.

Space – Efficient Design

Occupying only one slot in the SCXI chassis, the SCXI – 1180 is a space – efficient solution. In applications where space within the chassis is limited, such as in portable or compact data acquisition systems, this feature is extremely valuable. It allows users to add the functionality of accessing unconditioned signals without sacrificing too much space that could be used for other modules. This space – saving design also contributes to the overall compactness and portability of the SCXI system, making it easier to deploy in different environments.

Daisy – Chain Extension Capability

When used in conjunction with the SCXI – 1340, SCXI – 1341, or SCXI – 1342 cable assembly, the SCXI – 1180 can act as a daisy – chain extender. This enables access to signals on the cable between a module and a plug – in board. In a large – scale data acquisition network where multiple modules and boards are interconnected, this daisy – chain extension capability provides an additional level of flexibility in signal routing. It allows for the efficient distribution of signals across different components, ensuring that all parts of the system can communicate effectively and that data can be acquired and processed in a coordinated manner.

Typical Application Scenarios

In industrial data acquisition systems, the SCXI – 1180 is often used to connect various sensors to the SCXI system. For example, in a manufacturing plant, there may be numerous analog sensors measuring parameters such as temperature, pressure, and vibration. The SCXI – 1180 can be used to connect these sensors to the SCXI chassis, providing access to the unconditioned signals. These signals can then be conditioned and processed by other SCXI modules, allowing for real – time monitoring and control of the manufacturing process. By using the SCXI – 1180, plant operators can ensure that all available sensor data is being utilized, leading to more accurate process control and potentially improved product quality.

In research laboratories, especially those involved in electrical engineering or physics experiments, the SCXI – 1180 is valuable for connecting experimental setups to the data acquisition system. Researchers may be using custom – built signal generators or unique sensors to conduct experiments. The SCXI – 1180’s ability to integrate unconditioned signals makes it easy for them to connect these components to the SCXI chassis. This allows for precise data acquisition during experiments, enabling researchers to analyze and draw conclusions based on accurate and detailed data. For instance, in an experiment studying the behavior of electrical circuits under different conditions, the SCXI – 1180 can be used to connect the circuit outputs to the data acquisition system, providing a reliable way to measure and record the signals.

For test and measurement applications in the electronics industry, the SCXI – 1180 plays a crucial role. When testing electronic components or devices, it is often necessary to access multiple signals simultaneously. The SCXI – 1180 can be used to connect the test equipment, such as oscilloscopes or signal analyzers, to the SCXI system. This enables the efficient collection and analysis of data from the components under test. In a quality control setting, for example, where multiple electronic components are being tested for performance, the SCXI – 1180 can help ensure that all relevant signals are captured and processed, allowing for accurate assessment of the components’ quality.

SCXI – 1302: A terminal block that can be used in conjunction with the SCXI – 1180 for signal breakout. While the SCXI – 1180 focuses on integrating unconditioned signals into the SCXI chassis, the SCXI – 1302 provides a convenient way to connect and route these signals. In a data acquisition system where analog signals need to be connected to the SCXI system and then distributed to different modules for processing, the SCXI – 1180 can first bring in the unconditioned signals, and the SCXI – 1302 can be used to break out these signals to the appropriate channels.

PCI – 6221: A data acquisition board that can be used in a system with the SCXI – 1180. When using the SCXI – 1180 to read digital lines on a PCI – 6221, it is important to note that the SCXI – 1180 is not configured as part of the SCXI system in the traditional sense since it does not communicate with the backplane. The slot for the SCXI – 1180 should be labeled as “empty,” and the channel names of the PCI – 6221 are used to access the necessary lines. This combination can be useful in applications where digital signal acquisition from the PCI – 6221 needs to be integrated with the overall SCXI – based data acquisition setup.
