Product Description

The 1756-EN4TR Module is a redundant Ethernet/IP communication module designed for Rockwell Automation’s ControlLogix EN4TR platform. It supports high-availability applications with dual 10/100 Mbps Ethernet ports for seamless network redundancy, allowing direct integration with up to 4 ControlLogx chassis. Operating within a voltage range of 19.2–30 V DC and an extended temperature range of 0–60°C, it ensures reliability in harsh industrial environments such as manufacturing, energy, and process automation. The Rockwell EN4TR Redundant module offers rapid fault recovery, reducing downtime through synchronized data exchange between redundant pairs. While lacking a built-in screen or battery, its robust design prioritizes network stability and fault tolerance. Key advantages include deterministic performance and seamless redundancy, though it requires precise configuration for optimal operation. Ideal for mission-critical systems demanding uninterrupted connectivity.
