Allen-Bradley 1783-BMS20CA Industrial Ethernet Switch

The Allen-Bradley 1783-BMS20CA Stratix 5700 is a 20-port industrial Ethernet switch designed to anchor scalable, managed networks in rugged automation environments. It provides 16 x 10/100BASE-T copper ports for standard Ethernet devices and two FE Combo uplink ports that can operate as either RJ-45 copper or SFP connections, plus two dedicated 100BASE-FX SFP ports for fiber links. As part of the ArmorStratix 5700 family, this switch is built to endure harsh industrial conditions while delivering centralized management for networks that connect PLCs, HMIs, sensors, and actuators across factory floors. The 1783-BMS20CA enables flexible topologies by mixing copper and fiber segments and supports expanded Ethernet/IP networks within Rockwell Automation ecosystems. In addition, ArmorStratix 5700 switches, including the 1783-BMS20CA, emphasize rugged electrical immunity features such as damped oscillatory wave immunity per IEC 61000-4-18, helping maintain reliable operation in challenging environments.
