1783-NATR Configurable NAT Router 24V DC | Allen-Bradley

The Original New Allen-Bradley 1783-NATR Configurable NAT Router is a network address translation device designed to simplify industrial network integration. It enables multiple machines on a production line to use identical IP address settings while communicating over a plant-wide Ethernet network without requiring time-consuming IP reconfiguration. The router provides simple 1:1 NAT mapping between a machine subnet and a control network, supports up to 32 translation mappings, and is configurable via a web page or Electronic Data Sheet Add-on Profile.

Core Engineering Highlights:
1:1 Network Address Translation (NAT) | Up to 32 translation mappings | 3 x RJ45 Ethernet ports (10/100 Mbps) | Linear and Device Level Ring (DLR) topologies | Web page or EDS AOP configuration | SD card backup/restore | 24V DC (20.4–27.6V) | 150 mA current draw | –40°C to +60°C operating | DIN rail or panel mount
