GE IS420ESWBH3A Mark VIe IONet Industrial Ethernet Switch


The GE IS420ESWBH3A is an industrial IONet Ethernet switch designed exclusively for GE Speedtronic Mark VIe and Mark VIeS turbine control systems. It serves as the core network communication hub to realize real-time data exchange between controllers, I/O modules and local HMI devices in distributed automation architecture.


This unmanaged switch comes with 16-channel 10/100Base-TX RJ45 ports and supports redundant DC power supply. It adopts industrial hardware design with comprehensive status indicators and built-in data buffering, maintaining stable network transmission under strong electromagnetic interference environments. Widely used for turbine control cabinet maintenance, system expansion and spare parts stocking in power and oil & gas industries.
