Description
Product Overview
Model：IS420ESWBH3A
Brand：General Electric (GE Vernova)
Official Name：ESWB Industrial IONet Ethernet Switch
Applicable Platform：GE Speedtronic Mark VIe / Mark VIeS Turbine Control System
IS420ESWBH3A is an industrial unmanaged full-duplex Ethernet switch dedicated to the GE Mark VIe control system’s IONet network. It serves as the communication backbone to realize deterministic real-time data exchange between Mark VIe controllers, UCPA I/O packs, HMIs and other network devices.
This switch adopts store-and-forward switching architecture with built-in flow control, eliminating transmission collision risks for critical turbo-machinery scan cycles. It supports redundant power input to avoid single-point power failure and features ruggedized design suitable for turbine cabinet harsh environments. The hardware has reached OEM end-of-life and is available as new surplus or refurbished spare parts for legacy power plant gas turbine, steam turbine and generator control cabinet maintenance.
Key Features
