NI SCXI-1327 HIGH-VOLTAGE ATTENUATOR  TERMINAL BLOCK

Product Overview

The NI SCXI-1327 High Voltage Attenuator Terminal Block is a high performance signal conditioning module from National Instruments (NI). It is designed for use in SCXI (Signal Conditioning eXtensions for Instrumentation) systems, capable of attenuating high-voltage signals and converting them to low-voltage signals suitable for data acquisition system processing.

Functional Features

High-voltage attenuation:

SCXI-1327 has a high-voltage attenuation function that can safely and accurately attenuate high-voltage signals to avoid damage to the data acquisition system.

Multi-channel design:

The module usually provides multiple channels, which can handle multiple high-voltage signals at the same time, improving the acquisition efficiency and flexibility of the system.

High Precision:

The SCXI-1327 is manufactured with high-precision components and processes to ensure that the attenuated signal has low error and distortion.

Ease of use:

The design of the wiring terminal block makes connecting and disconnecting signals easy and fast, reducing the difficulty and complexity of operation.

Compatibility:

SCXI-1327 is highly compatible with NI's SCXI systems and other data acquisition systems, and can be seamlessly integrated into existing test and measurement environments.

Technical Parameters

The technical parameters of SCXI-1327 may vary depending on the specific model and manufacturer's updates. Below are some examples of common technical parameters:

Attenuation Level: Adjustable, usually including options such as 1:1 and 100:1.

Input Voltage Range: Depending on the specific model, higher input voltages are usually supported.

Output Voltage Range: Range of output voltage after attenuation, usually lower, suitable for data acquisition system processing.

Number of Channels: Multiple channels, the specific number depends on the model.

Accuracy: the accuracy of the attenuated signal, usually higher, to ensure the accuracy of the measurement results.

NI SCXI-1327 high voltage attenuator terminal block is widely used in various industrial automation and test and measurement fields, including but not limited to:

Power system: used to monitor and control high voltage signals in the power system to ensure the stable operation of the power system.

Industrial automation: in industrial automation control systems, to achieve the monitoring and control of high-voltage equipment.

Aerospace: in the aerospace field, for testing and analysing the performance of equipment in high voltage environments.

Automobile manufacturing: In the process of automobile manufacturing, testing and verification of high voltage components.

Precautions

Installation and Use:

When installing and using the SCXI-1327, be sure to follow the product manual and safety regulations to ensure proper installation and wiring.

Avoid use in humid, high temperature or corrosive environments, which may affect the performance and life of the module.

Maintenance and care:

Regularly inspect and maintain the module to detect and deal with potential problems in a timely manner.

Avoid using incompatible equipment and accessories, so as not to cause damage to the module.

Configuring the High-Voltage Attenuator

Each channel has a 100:1 high-voltage attenuator that you can enable or disable by changing switch settings as shown in Table 1. Each channel requires two switches that you must set in the same position for the attenuator to operate correctly. The switches are behind their corresponding terminals. 

 • Setbothswitches to the 100:1 position to attenuate the appropriate channel. This setting places a precision 100:1 divider in the circuit to divide the voltage by 100 before the voltage enters the module. 

 • Setbothswitches to the 1:1 position to bypass the attenuator of the appropriate channel. This setting removes the 100:1 divider from the input stage.
