Description

Brief Product Description

The Allen-Bradley 1783-ETAP2F is a high-performance 3-port EtherNet/IP tap designed to bridge copper and fiber optic networks in demanding industrial environments. This module enables seamless Device Level Ring (DLR) connectivity while providing long-distance data transmission through dual 100Base-FX fiber interfaces.

Advanced Fiber Optic Connectivity and Network Extension

The Allen-Bradley 1783-ETAP2F serves as a critical infrastructure component for expanding EtherNet/IP networks across vast industrial sites. This module features a versatile port configuration, including one 10/100 Mbps RJ45 copper port and two 100Base-FX fiber optic ports. By utilizing fiber optics, the device facilitates secure communication over distances reaching 2 kilometers, effectively overcoming the length limitations of standard copper cabling. The 1310nm optical wavelength and LC-type connectors ensure high-speed data integrity, while the 12.8dB power budget maintains signal strength through multiple connection points in complex topologies.

Industrial-Grade Reliability and Protection

Engineered for the rigors of the factory floor, the 1783-ETAP2F incorporates robust hardware protections to ensure continuous uptime. The module operates reliably within a broad temperature spectrum from -25°C to +60°C and features a rugged enclosure rated for 30G shock and 5G vibration resistance. To safeguard against electrical anomalies, the unit provides 8kV air and 6kV contact electrostatic discharge (ESD) protection. Because industrial environments are often electrically noisy, the fiber optic interfaces provide inherent immunity to electromagnetic interference (EMI), protecting critical control data from corruption.

Simplified Installation and System Integration

Rockwell Automation designed the 1783-ETAP2F with flexible deployment in mind, supporting both horizontal and vertical DIN-rail mounting to fit varied control cabinet layouts. The module consumes a maximum of 6.24W from a standard 24V DC power source, making it an energy-efficient addition to any PLC system. Transitioning between copper and fiber media happens transparently within the hardware, allowing for easy integration into existing Stratix or EtherNet/IP architectures without extensive software reconfiguration. Furthermore, global certifications including CE, Ex, and KC validate this tap for use in diverse international markets and hazardous locations.
