This module specifically utilizes a Fiber Optic interface to facilitate high-speed data exchange across the factory floor while providing total immunity to electrical noise. It handles complex industrial tasks, including high-speed I/O control, messaging, and integrated motion. We guarantee this unit is 100% Brand New, original factory stock, ensuring maximum lifecycle performance for your critical control architecture.

Technical Specifications

The 1756-EN2F delivers superior throughput compared to standard copper-based modules:

Engineering Advantages

The 1756-EN2F provides specific technical solutions for demanding industrial environments:

• EMI/RFI Immunity: By utilizing fiber optic media instead of copper, this module eliminates electromagnetic interference issues commonly found near high-voltage VFDs, motors, and welders. It prevents ground loops and ensures data integrity over longer distances.

• Integrated Motion over EtherNet/IP: This module coordinates up to 8 axes of motion. It synchronizes drive commands with nanosecond precision, reducing the need for dedicated motion hardware and simplifying cabinet layouts.

• High Connection Density: With support for 128 TCP/IP and 256 CIP connections, a single 1756-EN2F manages vast arrays of distributed I/O, HMI terminals, and third-party gateways without bottlenecking the network.

• Rapid Fault Diagnostics: Integrated status indicators and the scrolling display provide real-time IP address information and port status. This accelerates the commissioning process and reduces downtime during network troubleshooting.

FAQs

How does the 1756-EN2F differ from the 1756-EN2T?

The 1756-EN2F features a fiber optic port, whereas the 1756-EN2T uses a standard RJ45 copper port. You should choose the 1756-EN2F for environments with extreme electrical noise or when the distance between chassis exceeds the 100-meter copper limit.

Does this module support "Hot Swapping"?

Yes. The 1756-EN2F supports Removal and Insertion Under Power (RIUP). You can replace the module without shutting down the entire system or affecting other modules in the 1756 chassis, provided you follow standard industrial safety protocols.

What fiber optic cable type does this module require?

The 1756-EN2F typically requires 62.5/125 micron multi-mode fiber. Always verify your transceiver specifications to ensure matching wavelength and connector types for your specific network backbone.

Is this a refurbished unit?

Absolutely not. We supply the 1756-EN2F as 100% Brand New in original factory packaging. It has never been installed or utilized in a production environment, ensuring the full manufacturer-specified MTBF (Mean Time Between Failures).
