This is particularly beneficial in multi – channel high – voltage applications, such as in a high – voltage testing laboratory where multiple signals need to be connected and monitored simultaneously. The numerous connection points simplify the wiring process and reduce the likelihood of connection errors, enhancing the overall efficiency of the system.

Shielded Design

The shielded design of the SCXI – 1326 is a significant advantage. It helps in reducing electromagnetic interference, which is crucial in high – voltage environments where electrical noise can affect the accuracy of signal transmission. By minimizing interference, the SCXI – 1326 ensures that the high – voltage signals are transmitted clearly and accurately. This makes it suitable for applications where precise signal detection and control are required, such as in high – voltage power grid monitoring systems.

Typical Application Scenarios

In industrial power distribution systems, the SCXI – 1326 is used to manage high – voltage circuits. For instance, in a large – scale manufacturing facility, high – voltage electricity powers heavy – duty machinery. The SCXI – 1326 can be connected to the SCXI – 1162 or SCXI – 1162 HV modules to switch these high – voltage circuits on and off, protecting the equipment and ensuring the smooth operation of the manufacturing process. It can also be used to monitor high – voltage signals, providing real – time data on the power distribution system’s performance.

In high – voltage research laboratories, the SCXI – 1326 is essential for conducting experiments. When studying the behavior of high – voltage electrical components or materials, accurate control and routing of high – voltage signals are necessary. The SCXI – 1326 allows researchers to connect various high – voltage sensors and instruments to the SCXI system, enabling precise measurement and analysis of experimental data. This contributes to advancements in fields such as electrical engineering and materials science.

For power grid monitoring and control, the SCXI – 1326 plays a key role. High – voltage signals in the power grid need to be monitored and controlled to maintain grid stability. The SCXI – 1326 can be used to connect sensors that measure parameters like voltage, current, and power quality. By routing these high – voltage signals to the appropriate SCXI modules, the data can be processed and analyzed, allowing operators to detect and address any issues in the power grid promptly.

Related Model Recommendations

SCXI – 1324: Another high – voltage terminal block in the NI product line. While the SCXI – 1326 is designed for use with specific modules like the SCXI – 1162 series, the SCXI – 1324 is tailored for use with the SCXI – 1160 relay module. The SCXI – 1324 has 24 screw terminals compared to the SCXI – 1326‘s 48, and it may be more suitable for applications with fewer high – voltage connection requirements. However, both are used for high – voltage signal handling within the SCXI system.

SCXI – 1162: A module that the SCXI – 1326 is designed to work with. The SCXI – 1162 is a digital input module, and the SCXI – 1326 provides the connection interface for external high – voltage signals to this module. They are closely related in high – voltage digital input applications within the SCXI system. For example, in an industrial control system where high – voltage digital signals need to be input for equipment operation control, the SCXI – 1326 connects the signals to the SCXI – 1162 for further processing.

SCXI – 1162 HV: A high – voltage version of the SCXI – 1162 module. The SCXI – 1326 is also compatible with this module, and together they are used in applications that require handling even higher – voltage digital signals.
