1756-EN2TR — Allen-Bradley ControlLogix EtherNet/IP Communication Module | Original Spare Parts

As a procurement manager sourcing critical automation components, you need absolute confidence in both product authenticity and technical fit. The Allen-Bradley 1756-EN2TR is a dual-port EtherNet/IP communication module purpose-built for ControlLogix PLC systems, delivering deterministic 10/100 Mbps connectivity across complex industrial networks. This unit is 100% Brand New and Factory Sealed, sourced directly from authorized supply chains — never refurbished, never gray-market.

In demanding environments where network downtime translates directly to production loss, the 1756-EN2TR stands apart through its embedded Device Level Ring (DLR) support, enabling self-healing ring topologies without external managed switches. Designed for Oil & Gas, Power Generation, Automotive, and Chemical Processing industries, this module integrates seamlessly into existing ControlLogix PLC System architectures, reducing both infrastructure cost and single-point-of-failure risk. It is a genuine Original New spare part, not a substitute or compatible replacement.

Whether you are expanding a live Control Module network or replacing an end-of-life unit under tight shutdown windows, this module ships fast with full documentation. Contact us today for pricing and lead time.

Typical Application Scenarios

  • Oil & Gas Upstream/Downstream: Reliable EtherNet/IP backbone for distributed wellhead and refinery control nodes, where network resilience is non-negotiable.
  • Power Plants & Utilities: Integrates with SCADA and DCS systems for real-time supervisory control, supporting high-availability ring topologies critical to grid stability.
  • Automotive Assembly Lines: Coordinates multi-zone motion and I/O control across ControlLogix chassis in high-throughput body-in-white and powertrain lines.
  • Chemical & Petrochemical Processing: Conformal-coated design withstands corrosive atmospheres, moisture, and chemical vapor exposure in SIS and DCS-adjacent control loops.
  • Water & Wastewater Treatment: Supports remote I/O and HMI communication across geographically distributed pump stations and treatment facilities.

Core Features & Technical Advantages

  1. Dual RJ45 Ports with Embedded Switch: Eliminates the need for external network switches in linear or ring topologies — reducing hardware cost and cabinet footprint.
  2. Device Level Ring (DLR) Protocol Support: Achieves sub-millisecond fault recovery, maintaining Industrial Automation continuity even during cable or node failures.
  3. 10/100 Mbps Auto-Negotiation: Precision-tuned for real-time EtherNet/IP traffic, supporting up to 256 simultaneous CIP connections for high-density distributed architectures.
  4. Robust Conformal Coating: Factory-applied coating protects PCB and components against humidity, dust, and corrosive gases — rated for heavy-duty industrial deployment.
  5. Backplane Power Efficiency: Draws only 800 mA @ 5V DC and 5 mA @ 24V DC, minimizing chassis power budget impact in high-density slot configurations.
  6. Field-Upgradable Firmware: Update via ControlFLASH or RSLinx without chassis removal, reducing planned maintenance downtime.

FAQ — Frequently Asked Questions

Q: What is the price of the 1756-EN2TR and do you offer volume discounts?
A: Pricing for the 1756-EN2TR is competitive and reflects genuine Original New stock with full traceability. Volume discounts are available for orders of 3 units or more. Contact sale@ninermas.com with your quantity and project timeline for a formal quotation within 24 hours.

Q: What is the lead time for the 1756-EN2TR?
A: In-stock units ship within 1-2 business days. For larger quantities or specific firmware revisions, lead time is typically 3-7 business days. Emergency same-day dispatch is available for critical plant shutdowns — contact us directly.

Q: Can you provide a Datasheet or Certificate of Origin for the 1756-EN2TR?
A: Yes. The official Allen-Bradley 1756-EN2TR datasheet, Certificate of Conformity, and country-of-origin documentation are available upon request. These documents support customs clearance, engineering review, and procurement compliance requirements.

Q: Is this module compatible with all ControlLogix 1756 chassis?
A: The 1756-EN2TR is compatible with all standard 1756-series ControlLogix chassis. Verify your Studio 5000 / RSLogix 5000 software version supports the module’s firmware revision for full feature compatibility.

Q: What is the difference between 1756-EN2T and 1756-EN2TR?
A: The “R” suffix denotes conformal coating applied to the PCB assembly, providing enhanced protection against humidity, dust, and corrosive industrial atmospheres. For standard office or clean-room environments, the 1756-EN2T is sufficient; for harsh industrial sites, the 1756-EN2TR is the recommended Industrial Automation Control Module.

Q: How do I verify the authenticity of the 1756-EN2TR I receive?
A: Every unit we supply is 100% Original and Brand New, traceable to authorized distribution channels. Serial numbers can be verified through Rockwell Automation’s product authentication portal. We provide full documentation to support your incoming inspection process.
