Allen-Bradley 1719-AENTR Ex I/O EtherNet/IP Communication Adapter

Product Overview

The Allen-Bradley 1719-AENTR acts as the primary communication gateway for the 1719 Ex I/O chassis. This high-performance EtherNet/IP adapter enables seamless data exchange between intrinsically safe field devices and a standard ControlLogix or CompactLogix controller. It facilitates the mounting of I/O modules directly in hazardous locations, reducing the need for expensive explosion-proof enclosures or extensive long-distance cabling. We supply this module as 100% Brand New and Original, ensuring your hazardous area network meets stringent regulatory and safety standards.

Engineering Advantages

• Direct Hazardous Area Mounting: The 1719-AENTR carries certifications for Zone 2 and Class 1, Division 2 environments. This eliminates the requirement for traditional purging systems or heavy cast-iron enclosures, significantly lowering the total cost of installation.

• Network Resiliency via DLR: The dual-port design supports Device Level Ring (DLR) topology. This architecture provides hardware-level redundancy; if a cable break occurs, the adapter automatically reroutes traffic in milliseconds, preventing process downtime in critical chemical or oil and gas applications.

• Intrinsically Safe Integration: The module manages the power and data distribution to the 1719 Ex I/O backplane. It ensures that electrical energy remains below the ignition threshold, providing a native "Ex i" interface for sensors and actuators located in Zone 0 or Zone 1.

• Simplified System Architecture: By utilizing EtherNet/IP, this adapter allows engineers to treat hazardous area I/O exactly like standard I/O within the Studio 5000 environment. This unified software approach accelerates commissioning and simplifies long-term maintenance.

FAQs

• Does the 1719-AENTR support high-availability configurations?

  Yes. The adapter supports Device Level Ring (DLR) and can operate within redundant controller architectures. It ensures that the I/O remains accessible even if one network path fails.

• Can I install this adapter in a Zone 1 area?

  No. The 1719-AENTR itself must reside in a Zone 2 or Class 1, Division 2 area. However, the I/O modules it controls can interface with field devices located in Zone 1 or Zone 0 through the intrinsically safe backplane.

• What power supply is required for the 1719-AENTR?

  The module requires a 12V DC input. It typically draws power from the 1719-PSDC power supply module mounted within the same 1719 chassis, which regulates the power for the entire I/O assembly.

• Is this a brand new unit?

  We guarantee that this 1719-AENTR is 100% Brand New and Original. It ships in factory packaging with all original certifications and documentation intact.
