Technical Specifications

Application Fields

This module excels in applications requiring high-speed data acquisition and reliable signal processing. You might notice that industries like automotive manufacturing, food processing, and packaging machinery benefit greatly from its performance. For example, one customer mentioned how the module’s fast response time improved their conveyor system’s efficiency by reducing lag in sensor feedback.

Advantages & Value

One thing I appreciate is the balance between cost and functionality. In many cases, companies struggle to find components that offer both affordability and premium quality. The 140DDI36400 addresses this by providing seamless integration with existing systems, reducing compatibility issues. Additionally, its durability ensures long-term operation even in harsh conditions, translating into fewer replacements and lower maintenance costs over time.

Installation & Maintenance

For optimal performance, ensure the module is installed in a well-ventilated cabinet with proper grounding. Wiring should comply with standard electrical safety practices to avoid short circuits. Routine maintenance includes periodic firmware updates—typically released every six months—and cleaning dust accumulation around the unit using compressed air. Calibration isn’t usually required unless operating under extreme environmental conditions.

Quality & Certifications

Backed by certifications such as CE, UL, and RoHS compliance, the 140DDI36400 guarantees adherence to international safety and environmental standards. The manufacturer also offers a 12-month warranty, covering defects in materials and workmanship. If issues arise, technical support is available to guide you through troubleshooting steps or replacement procedures.
