Information About 1756-EN3TR
The 1756-EN3TR belongs to the Allen-Bradley ControlLogix communication family and provides high-performance EtherNet/IP networking for local or remote chassis installations. With embedded switch technology, the dual Ethernet ports support linear, star, and Device Level Ring (DLR) topologies, ensuring network flexibility and resilience. This module supports up to 128 CIP motion axes, 128 TCP/IP connections, and 256 Logix connections, making it suitable for large-scale control systems. It draws 1 A at 5.1V DC and 3 mA at 24V DC from the backplane, with a power dissipation of approximately 5.1 W. Designed for reliability, it operates within a temperature range of 32–140 °F (0–60 °C) and provides continuous 30V insulation voltage protection. Compact and versatile, the 1756-EN3TR allows seamless integration of EtherNet/IP networks with advanced motion, I/O, and information exchange.
Key Features:
- Ethernet Connectivity: Two RJ45 ports supporting 10/100 Mbps with embedded switch technology for flexible topologies.
- USB Interface: One USB 2.0 port (12 Mbps) for configuration, programming, and diagnostics.
- Supported Topologies: Linear, star, and Device Level Ring (DLR) for network redundancy and uptime.
- Motion Support: Handles up to 128 CIP motion axes and up to 255 total axes for advanced motion applications.
- Connection Capacity: Supports 128 TCP/IP and 256 Logix connections for large-scale system integration.
- Power Requirements: Consumes 1 A @ 5.1V DC and 3 mA @ 24V DC with 5.1 W maximum power dissipation.
- Environmental Ratings: Operates from 0–60 °C (32–140 °F) with 30V continuous insulation voltage.
- Application Use: Suitable for real-time I/O messaging, controller communication, and enterprise-level integration.
The 1756-EN3TR delivers robust EtherNet/IP connectivity, high connection capacity, and reliable motion support for modern ControlLogix automation systems.
