Allen Bradley 1734-AENTR Point I/O Dual Port Ethernet/IP Adapter

Product Introduction

The Allen Bradley 1734-AENTR POINT I/O Dual Port EtherNet/IP Adapter is a high-performance distributed I/O communication adapter designed for the POINT I/O system. Manufactured by Allen-Bradley, it enables seamless integration of modular I/O blocks into EtherNet/IP industrial networks, supporting flexible and scalable automation architectures.

Equipped with dual Ethernet ports, the module supports advanced network topologies such as Device Level Ring (DLR), star, tree, and linear configurations, improving network resilience and communication reliability. It can manage up to 63 POINT I/O modules on a single backplane (POINTBus), making it highly suitable for distributed control systems requiring modular expansion and high connectivity.

With support for both direct and rack-optimized connections, the 1734-AENTR ensures efficient data exchange between PLCs and field devices, reducing network load while maintaining deterministic communication performance.
