Siemens 6GK5124-0BA00-2AA3 Industrial Ethernet Switch

Siemens 6GK5124-0BA00-2AA3 is a SCALANCE X124 unmanaged Industrial Ethernet switch from the SIMATIC NET family. It provides 24x 10/100 Mbps RJ-45 ports for straightforward device-to-device networking in small to mid-size automation networks, enabling star and line topologies without configuration. The device is housed in an IP20 enclosure and supports DIN-rail (35 mm) mounting as well as wall mounting with compatible brackets. Front-panel LED diagnostics give quick status visibility, and a fault signaling contact with a pushbutton facilitates local fault indication and reset. It supports a redundant power supply supplied from 24 V AC or 24 V DC input, helping ensure network availability in factory environments. Because it is unmanaged, the switch operates without software configuration and integrates with Siemens controllers and devices via SIMATIC Net, making it suitable for connecting PLCs, operator interfaces, sensors, and actuators in compact industrial networks.
