The Allen-Bradley 1756-EN4TR provides two 1 Gigabit Ethernet ports as a ControlLogix EtherNet/IP interface module. It connects ControlLogix controllers to industrial networks for high-speed data exchange, supporting dual-port topologies that enable media redundancy or separate network segments on the same chassis. The module handles CIP messaging and integrates with controllers, I/O, and HMI devices in automation systems where 1 Gbps throughput is required.
