The IS420ESWAH3A – IONet Ethernet Switch is a compact, robust, and reliable networking component used in GE’s Mark VIe control systems. Engineered for high-performance industrial environments, this switch serves as a critical component in managing Ethernet communication across turbine control applications, distributed control systems, and process automation networks.

Built with 8 ports, the IS420ESWAH3A allows for fast and redundant Ethernet communication between controllers, I/O modules, and human-machine interfaces (HMIs) using the IONet protocol. IONet (Industrial Ethernet) is GE’s dedicated network system used to ensure deterministic and real-time communication, essential for gas turbines, steam turbines, and power plant automation systems.

This switch is DIN-rail mountable and features redundant power inputs, helping reduce the risk of single-point failure. Its rugged industrial housing ensures it can operate reliably in harsh environments — including high-temperature areas, dusty industrial floors, or locations with potential electromagnetic interference.

The IS420ESWAH3A also includes built-in diagnostics and LED indicators, allowing operators to monitor port status and network health easily. These features help minimize downtime and enable quick troubleshooting in case of faults. Whether you are designing a new turbine control system or performing a retrofit on an existing one, this switch fits seamlessly into GE’s Mark VIe ecosystem.

Thanks to plug-and-play support and compliance with IEEE 802.3, installation and integration are fast and reliable. The unit’s low power consumption and energy-efficient operation make it ideal for long-term industrial applications.
