NI SCXI-1349

Description

• The NI SCXI-1349 you inquired about previously is a cable adapter used within National Instruments’ SCXI (Signal Conditioning eXtensions for Instrumentation) platform for data acquisition applications.

  Here’s a summary of its function and key features based on previous searches:

  • Function: The SCXI-1349 acts as an interface between an SCXI system and a National Instruments data acquisition (DAQ) device. It essentially bridges the gap between the SCXI backplane and the DAQ device, allowing for signal routing and power supply connections.

  • Compatibility: It’s important to note that the SCXI-1349 is designed for use with E Series DAQ devices, excluding 61XXE models. This ensures compatibility with the pin configuration and voltage requirements of these specific DAQ modules.

  • Key Features:

  • •  50-pin and 68-pin Connectors: The SCXI-1349 features a 50-pin connector for connection to the SCXI backplane and a 68-pin connector for interfacing with the E Series DAQ device. These connectors provide the necessary pathways for signal routing between the SCXI system and the DAQ module.
    • Power Supply: In addition to signal routing, the cable adapter likely includes pins dedicated to power supply connections, ensuring the E Series DAQ device receives the required voltage for operation.
    • Shielded Design: The cable is likely shielded to minimize electrical noise and ensure reliable signal transmission, especially crucial for accurate data acquisition.

  Applications (within National Instruments SCXI systems):

  • Expanding DAQ Capabilities: The SCXI-1349 enables the use of E Series DAQ devices within an SCXI system. This expands the data acquisition capabilities of the SCXI platform by allowing users to leverage the functionalities of various E Series DAQ modules, such as:

    • Analog input/output modules for voltage, current, or temperature measurements
    • Digital input/output modules for controlling relays, solenoids, or other actuators

  • Modular System Configuration: The SCXI platform offers a modular design, and the SCXI-1349 facilitates this by enabling the seamless integration of E Series DAQ modules into the system. Users can choose the appropriate DAQ modules based on their specific measurement or control requirements.

  Finding More Information:

• A detailed datasheet for the NI SCXI-1349 is essential for understanding the specific pin configurations, voltage ratings, and compatibility details for your application. Here are some resources for locating the datasheet:
