Description

The Allen-Bradley 1756-EN2TRK is a high-performance EtherNet/IP communication bridge module designed for the ControlLogix platform. This specific variant features factory-applied conformal coating, providing enhanced protection for internal circuitry against harsh environmental factors such as humidity, corrosive gases, and airborne contaminants. It serves as a robust network interface for real-time I/O control, safety messaging, and controller-to-controller communication, making it suitable for demanding industrial sectors including mining, water treatment, and chemical processing.

Features

  • Conformal Coating: Specialized protection for internal electronic assemblies against chemical exposure and condensation.
  • Dual-Port Architecture: Two RJ45 Ethernet ports supporting linear, star, and Device Level Ring (DLR) network topologies.
  • Network Resilience: Supports DLR to maintain network integrity and prevent communication loss during cable failures.
  • High-Speed Communication: 10/100 Mbps Ethernet with automatic negotiation for seamless integration into existing plant networks.
  • Diagnostic Support: Includes a dedicated USB port for local configuration and troubleshooting.

Applications

This module is intended for use in ControlLogix chassis-based systems where network reliability is critical. It is frequently deployed in applications requiring redundant network paths, high-speed data exchange between controllers, and operation in environments where standard electronic components might be susceptible to atmospheric degradation.

Installation Guidelines

  • Ensure the ControlLogix chassis is powered down before inserting or removing the module.
  • The module occupies one standard slot in the chassis; it can be placed in any available slot.
  • Use shielded Ethernet cabling to minimize EMI interference in high-noise industrial environments.
  • Verify that the module is properly seated and the locking mechanism is engaged to ensure a secure backplane connection.
  • Maintain proper ventilation within the cabinet to stay within the 0 to 60 deg C operating temperature range.

FAQ

Q: Does this module require a managed switch?
A: No, the 1756-EN2TRK features built-in dual-port architecture that supports DLR and linear topologies, eliminating the need for external managed switches in many configurations.

Q: Can this module be used in standard ControlLogix chassis?
A: Yes, it is fully compatible with standard ControlLogix chassis and occupies a single slot.
