Overview
The NetBurner SB72EX-100CR is a serial-to-Ethernet gateway engineered for Allen-Bradley ControlLogix and SLC 5/05 platforms. This industrial-grade device enables secure remote access and monitoring by converting dual serial ports to Ethernet connectivity with SSL and SSH encryption. The SB72EX-100CR is often referenced as the RTA Automation 435NBS ASCII ControlLogix variant, making it a critical component in legacy and modern automation networks requiring serial protocol bridging.
