Allen Bradley 1783-NATR Network Address Translation Router

Product Introduction

The Allen-Bradley 1783-NATR Network Address Translation Router is an industrial-grade NAT (Network Address Translation) router designed to provide secure and flexible networking for EtherNet/IP and industrial automation systems. It belongs to the Allen-Bradley Stratix Industrial Networking Portfolio, offering network segmentation, address translation, and support for Device Level Ring (DLR) topologies.

The 1783-NATR router enables 1:1 NAT with up to 32 translation mappings, allowing devices in different subnets to communicate securely without IP conflicts. It supports both linear and DLR network architectures, providing flexible integration into complex industrial automation networks. Configuration can be performed via web interface or EDS/AOP tools, and an SD card is available for configuration storage and firmware updates.

This device is commonly deployed in industrial control cabinets, machine automation systems, and plant-level EtherNet/IP networks, ensuring secure communication between devices while maintaining network resilience and scalability.
