Allen-Bradley | 1734-AENTR | POINT I/O

Product Description: Allen-Bradley 1734-AENTR

The Allen-Bradley 1734-AENTR is a dual-port EtherNet/IP communication adapter for the POINT I/O system. It enables POINT I/O modules to operate as part of an EtherNet/IP network, providing high- speed, deterministic control data exchange between the I/O modules and a Logix-based controller. With integrated dual Ethernet ports, it supports Device Level Ring (DLR) topology for network redundancy and reliability.
