1715-TADIF16 | Allen Bradley Redundant Analog Input Termination Assembly

Product Overview

The Allen Bradley 1715-TADIF16 acts as a high-integrity Duplex Analog Input Termination Assembly designed for the 1715 Redundant I/O system. This assembly facilitates the connection between field sensors and redundant I/O modules, providing 16 channels of high-availability signal processing. It ensures continuous operation in critical environments where system downtime poses significant risks. We supply this component as 100% Brand New, ensuring original factory reliability for your fault-tolerant architecture.

Technical Specifications

Engineering Advantages

• Fault-Tolerant Redundancy: The 1715-TADIF16 supports duplex configurations, allowing two I/O modules to process the same field signals simultaneously. This architecture eliminates single points of failure within the I/O layer.

• Granular Channel Protection: Each of the 16 channels features an individual 50 mA, 125V Type T fuse. This design isolates field-side faults to a single loop, preventing a surge in one sensor from compromising the entire termination assembly.

• High-Precision Conversion: The assembly provides a resolution of 0.0039 mA per count. This 12-bit precision over the standard 4–20 mA range enables the control system to detect minute process fluctuations, which is essential for sensitive chemical or power generation applications.

• Simplified Installation and Maintenance: The compact 8.4 cm width optimizes DIN rail space. Use a 0.4 x 2.0 mm flathead screwdriver to secure field wiring to the 0.5 N•m torque specifications, ensuring vibration-resistant connections in high-motion industrial environments.

FAQs

• Is this 1715-TADIF16 unit brand new or refurbished?

  We offer this product as 100% Brand New in its original factory packaging. This ensures the unit meets all current Rockwell Automation technical standards and has no previous service history.

• What is the primary difference between the 1715-TASIF16 and the 1715-TADIF16?

  The "S" in TASIF16 stands for Simplex, while the "D" in TADIF16 stands for Duplex. Use the 1715-TADIF16 when your application requires redundant I/O modules for increased system availability.

• Can I replace individual fuses on this termination assembly?

  Yes. Each channel utilizes a 50 mA, 125V Type T fuse. You should always verify the field loop current before replacement to ensure no underlying short circuit exists in the field wiring.

• Why does the specification require shielded wire?

  Shielded wiring prevents electromagnetic interference (EMI) from distorting the 4–20 mA analog signals. This is particularly critical for the 1715-TADIF16 due to its high 12-bit resolution, where even minor noise can impact data accuracy.
