Overview

The GE IS420ESWBH2A is an industrial-grade Ethernet switch board designed for GE’s Mark VIe / Mark VIeS SPEEDTRONIC turbine control systems. It ensures high-speed, deterministic communication between controllers, I/O modules, protection devices, and other critical subsystems.

Built on N-TRON industrial networking technology, the IS420ESWBH2A provides robust data transfer with advanced synchronization features. It supports IONet, GE’s real-time Ethernet protocol, delivering refresh cycles as fast as ≤5 ms, making it ideal for mission-critical turbine operations requiring precision, redundancy, and maximum uptime.

Technical Data

Application

The GE IS420ESWBH2A is widely used in power generation, oil & gas, and heavy industrial facilities for:

• Gas and steam turbine control networks requiring deterministic, low-latency communication.

• Overspeed protection, trip systems, and interlocking where timing precision is critical.

• Redundant control architectures needing reliable fiber/copper Ethernet switching.

• Industrial automation networks demanding rugged hardware with wide temperature tolerance.

• IO-to-controller real-time data exchange across IONet networks.

Its deterministic performance, PTP timing accuracy, and rugged design make it a trusted component in turbine safety and performance optimization architectures.
