Allen-Bradley | 1783-NATR | Stratix 2000/Stratix NAT

Product Description: Allen-Bradley 1783-NATR

The Allen-Bradley 1783-NATR is a Network Address Translation (NAT) device designed to simplify IP address management in industrial Ethernet networks. It allows multiple machines or skid systems with identical IP addresses to connect to a single control system by translating the internal IP addresses to unique external addresses. With its compact size and DIN rail mounting, it is ideal for use in OEM and machine builder applications requiring plug-and-play connectivity without reconfiguring PLC or HMI IP settings.
