If you need network isolation on a production line, you’ll likely need address conversion hardware. That’s where the Allen Bradley 1783-NATR comes in. Its NAT routing makes this straightforward. It runs on standard 24V DC power. Two 10/100Mbps Ethernet ports sit on the front to connect your internal and external networks. With older routers, you’d have to redo all your global addressing. This module avoids that. Devices keep their original IPs. You don’t have to reconfigure individual machines just to troubleshoot. Hanyite Automation Technology has verified these units. We work with authorized suppliers, so brand-new stock is available. It’s a reliable choice for securing industrial control network boundaries.

Upstream factory network access downstream port → Allen Bradley 1783-NATR performs source IP address and MAC address mapping conversion → Internal private network data packets strip the original address and allocate a legal public IP → Routing module performs cross-subnet data packet forwarding → Upstream port delivers the reconstructed data frame to the external main network → External response data arrives at the upstream port → Routing module reversely restores the destination address based on the NAT mapping table → Data packets are accurately delivered to the internal private network target device
Isolates the private network of the workshop from the factory main network using NAT technology, preventing local broadcast storms from causing global network paralysis, while retaining the original IP configuration of devices within the micro-network segment, eliminating the debugging costs caused by large-scale address relocation, and Allen Bradley 1783-NATR provides reliable logical isolation and data penetration mechanisms at the industrial control network boundary.
Reduces the debugging cycle for network integration of workshop equipment, avoiding the time-consuming troubleshooting caused by modifying private addresses one by one
Reduces the packet loss rate in cross-subnet communication, ensuring real-time interaction of control instructions and collected data
Reduces the number of core switch routing table entries, improving the overall forwarding performance of the factory main network
Eliminates the impact of external network changes on internal terminals, maintaining the continuous operation of the devices connected to Allen Bradley 1783-NATR
