GE IS420ESWBH2A Industrial IONet Ethernet Switch – Product Description

Overview

The GE IS420ESWBH2A is an industrial Ethernet switch designed for real-time communication inside Mark VIe control systems. It links controllers, I/O packs, operator interfaces, and networked turbine devices using a deterministic IONet structure optimized for protection and automation tasks. Moreover, its hardware design ensures stable operation in hazardous and high-temperature environments, making it suitable for demanding turbine and process applications.

The switch provides consistent performance in gas turbines, steam turbines, refineries, and chemical plants where robust networking is essential. In addition, its unmanaged architecture eliminates configuration complexity while still meeting the strict timing requirements of GE’s control networks.
