RTA Automation SB72EX-100CR Industrial Ethernet Gateway

The SB72EX-100CR is a two-port serial-to-Ethernet gateway built on NetBurner hardware, designed to bridge legacy Allen-Bradley ControlLogix and SLC 5/05 PLCs to Ethernet networks, enabling serial data streams to move onto IP networks for remote access and monitoring. The unit provides two serial interfaces and a 10/100BASE-T Ethernet port, with SSL and SSH encryption to secure remote connections, making it suitable for industrial environments where protecting data-in-transit between field devices and IT networks is essential. In practice, the SB72EX-100CR is often referenced as the NetBurner-based ASCII ControlLogix gateway by distributors, a description that reflects its role as a gateway for bridging ASCII-mode serial traffic to Ethernet and integrating with legacy AB equipment. Common applications include remote device monitoring, data collection from serial sensors, and integration of legacy serial equipment with modern Ethernet networks, where the gateway acts as a bridge between serial protocols and TCP/IP, without requiring changes to existing hardware on the PLC side.
