Product Details
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.

Tech & Buying Guide
Redundant Automation Systems: Ensuring Continuous Uptime in Critical Control Infrastructure
System reliability directly determines operational profitability across high stakes process industries. Modern industrial automation platforms must eliminate single points of failure to prevent catastrophic shutdowns. Deploying fault tolerant architecture safeguards complex facilities against unexpected hardware glitches, network disruptions, and maintenance outages.
Understanding Types of Noise in Electronic Circuits and Control Systems
Signal integrity directly determines measurement accuracy and loop stability across industrial automation environments. Electronic noise introduces unwanted stochastic interference into analog loops, sensor feedback lines, and digital fieldbus networks. Understanding how intrinsic electronic noise and external electromagnetic interference manifest allows control engineers to optimize signal conditioning and shield sensitive instrumentation effectively.
Why 24V DC Power Supplies Standardize Modern Industrial Automation
Industrial control cabinets worldwide rely on 24V DC as the universal power standard for field instrumentation, sensors, and controllers. Walk into any manufacturing plant, and you will find PLCs, human-machine interfaces (HMIs), and smart actuators running on extra-low voltage DC. Standardizing on 24V DC enhances operational safety, lowers cabinet footprint, and maintains steady control performance across factory networks.
