Overview
The Allen-Bradley 1769-AENTR is a network adapter module designed to integrate Ethernet/IP connectivity into CompactLogix automation systems. Part of Rockwell Automation’s Compact I/O family, this adapter allows users to deploy 1769 I/O modules over an EtherNet/IP network, eliminating the need for redundant spare parts inventory and enabling cost-effective platform upgrades. With its compact form factor and dual Ethernet interfaces, the 1769-AENTR simplifies control architecture and provides flexible network topology support.
Key Features
- Dual Ethernet ports supporting 10/100 Mbps communication with RJ45 connectors
- Network topology flexibility: Supports star, linear, and Device Level Ring (DLR) architectures
- 69 I/O points with 96 TCP/IP and 128 logical EtherNet/IP connections
- I/O preservation: Enables reuse of existing 1769 I/O modules when migrating to next-generation CompactLogix controllers
- Compact design: DIN rail and panel mount options for space-efficient cabinet integration
- IP security and motion control support for advanced automation applications
- Rotary switch IP address configuration for simplified setup and commissioning
