Allen-Bradley 1715-AENTR EtherNet/IP Adapter

Description

The Allen-Bradley 1715-AENTR EtherNet/IP Adapter is a dedicated communication module designed exclusively for the 1715 redundant I/O system, enabling reliable EtherNet/IP network connectivity for industrial control setups. Key technical specifications include support for up to 24 I/O modules per adapter pair, a maximum power draw of 8 watts, and a weight of 420 grams. It features an auto-sensing 10/100BASE-TX Ethernet port, uses a 45 AWG shielded RJ12 connector, and operates in environments with temperatures ranging from -20 degrees Celsius to 70 degrees Celsius, and humidity from 5% to 95% non-condensing.

This adapter supports both Device Level Ring (DLR) and star topologies, and its dual Ethernet ports enable redundant network construction, ensuring seamless failover between primary and backup links to prevent communication interruptions during single-point failures. Core functions include real-time data transmission and system collaboration by connecting controllers to EtherNet/IP-compatible devices such as HMIs and sensors. It also offers high-availability features like hot-swappable capability for maintenance without system downtime, and built-in diagnostic tools that monitor for anomalies such as open or short circuits and trigger alerts. Installation is flexible with support for DIN rail or panel mounting, and it eliminates the need for cross-wiring I/O by using the 1715 backplane’s intelligent sensing for module switching, simplifying system configuration without requiring additional programming code.
