Genuine Allen-Bradley 1756-EN2F ControlLogix EtherNet/IP Fiber Optic Communication Module | 1756 Series – Verified Source
The Allen-Bradley 1756-EN2F is a mission-critical EtherNet/IP communication bridge module within Rockwell Automation’s ControlLogix 1756 platform — one of the most widely deployed industrial control architectures in process manufacturing, oil & gas, automotive, and utilities worldwide. Its fiber optic interface enables noise-immune, long-distance network connectivity in electrically harsh environments where copper-based alternatives fail. Due to its high demand and premium price point, the 1756-EN2F is among the most frequently counterfeited and misrepresented PLC modules on the secondary market. Buyers sourcing from unverified distributors risk receiving refurbished units sold as new, cloned hardware with degraded firmware, or modules with falsified date codes — all of which pose serious risks to production uptime and system integrity.
At Konmask, every 1756-EN2F unit we supply is sourced through verified, traceable supply channels and subjected to our in-house 4-step quality verification process before shipment. We provide full documentation including Certificate of Conformance (COC), test reports, original packaging photos, packing list, and Country of Origin (COO) declaration upon request. Our commitment is simple: you receive a genuine, authentic, verified Allen-Bradley 1756-EN2F — or we make it right. Konmask serves industrial buyers, MRO procurement teams, and systems integrators who cannot afford the risk of counterfeit automation hardware.

Our 4-Step Quality Verification Process
- Step 1 — Visual & Cosmetic Inspection: Each unit is examined under controlled lighting for label authenticity (holographic Rockwell seals, correct date codes, revision markings), housing integrity, connector condition, and absence of re-work or solder rework indicators. Units with any signs of tampering are immediately quarantined.
- Step 2 — Firmware & Serial Number Verification: We verify the module’s embedded firmware version and cross-reference the serial number against known authentic production batches. Cloned or flashed units are identified and rejected at this stage.
- Step 3 — Functional Power-On & Communication Test: The 1756-EN2F is installed in a live 1756 chassis and tested for successful backplane communication, EtherNet/IP node registration, and fiber link establishment. Network diagnostics are logged and available as a test report upon request.
- Step 4 — Documentation Package Preparation: Upon passing all three prior steps, we prepare the full documentation set: Certificate of Conformance (COC), functional test report, original packaging photos, packing list, and COO Declaration. All documents are available to buyers before or after shipment.
Key Features & Benefits
- Fiber Optic Immunity: SC multi-mode fiber interface eliminates electromagnetic interference (EMI) susceptibility — compliant with IEC 61000-4 immunity standards for industrial environments.
- Extended Reach Networking: Supports EtherNet/IP segments up to 2 km, enabling plant-wide or campus-scale ControlLogix network architectures without signal repeaters.
- Dual-Port Backplane Integration: Seamlessly integrates into the 1756 ControlLogix backplane, supporting both controller-class and adapter-class operation for flexible topology design.
- High-Speed Deterministic Communication: 100 Mbps full-duplex fiber link ensures low-latency, deterministic I/O data exchange — critical for time-sensitive process control loops per IEC 61784-2.
- ControlFLASH Firmware Upgradeable: Field firmware updates via Rockwell’s ControlFLASH utility ensure long-term compatibility with evolving Studio 5000 / RSLogix 5000 environments.
- ATEX Zone 2 Rated: Suitable for deployment in potentially explosive atmospheres (gas group IIC, temperature class T4), meeting ATEX Directive 2014/34/EU requirements for hazardous area installations.
Typical Applications
- Oil & Gas: Upstream wellhead control and downstream refinery DCS-to-PLC integration over long-distance fiber backbones in electrically noisy environments.
- Automotive Manufacturing: High-speed body shop and paint line automation where copper Ethernet is susceptible to weld-cell EMI interference.
- Water & Wastewater Treatment: SCADA-to-ControlLogix communication across geographically distributed pump stations and treatment facilities.
- Power Generation & Utilities: Substation automation and turbine control networks requiring galvanic isolation and long-distance fiber runs between control rooms and field equipment.
- Pharmaceutical & Life Sciences: FDA-regulated batch process control systems requiring validated, traceable hardware with full documentation for 21 CFR Part 11 compliance support.
- Mining & Metals: Conveyor, crusher, and smelter control systems operating in high-vibration, high-EMI environments where fiber optic links provide superior reliability over copper.
