Main Features and Advantages

Versatile Connectivity: The NI SCXI-1349 eliminates compatibility barriers by connecting 68-pin E-Series DAQ devices to SCXI modules. Its triple-connector design supports flexible wiring setups, allowing users to route signals between DAQ cards, signal conditioning modules, and external equipment with ease.
Reliable Signal Transmission: Engineered with high-voltage protection (up to 60 Vdc), the adapter safeguards both hardware and operators from electrical hazards. Its shielded construction minimizes electromagnetic interference (EMI), ensuring clean signal integrity in noisy environments.
Easy Integration with SCXI Ecosystem: As a dedicated interface for SCXI systems, the SCXI-1349 simplifies integration with NI’s signal conditioning modules, such as amplifiers, filters, and bridges. This enables users to expand measurement capabilities for applications like strain gauging, thermocouple monitoring, or high-precision voltage sensing.
Robust Industrial Design: Built to withstand industrial conditions, the adapter features durable connectors and a rugged casing. Its wide temperature range (0°C to 50°C) and non-condensing humidity tolerance make it suitable for both laboratory setups and harsh factory floors.
Cost-Effective System Expansion: By reusing existing E-Series DAQ hardware, the SCXI-1349 allows users to upgrade systems with signal conditioning capabilities without replacing core components. This makes it a cost-efficient solution for scaling measurement setups.

Application Field

The NI SCXI-1349 is widely used in industrial automation and research laboratories where precise signal conditioning is essential. In manufacturing, it supports quality control by enabling DAQ devices to interface with SCXI modules for monitoring machine vibrations, temperature fluctuations, or pressure changes in production lines. For academic research, the adapter facilitates complex experiments in materials science, where it connects strain gauges or load cells to DAQ systems via SCXI signal conditioners, allowing students and researchers to collect high-fidelity data.

In the energy sector, the SCXI-1349 plays a role in renewable energy monitoring, such as connecting solar panel voltage sensors or wind turbine vibration sensors to DAQ devices through SCXI modules. It is also utilized in automotive testing for engine performance analysis, where it bridges DAQ systems with SCXI-based charge amplifiers for piezoelectric sensor data. Additionally, the adapter supports biomedical research by enabling DAQ devices to interface with SCXI modules for amplifying and filtering physiological signals like ECG or EMG readings.
